Ankle Sprain Not Healing? Signs It May Be More Than a Sprain
You rolled your ankle, gave it some rest, and expected the pain and swelling to fade. But days—or even weeks—later, you're still limping. Maybe the ankle feels weak, or every attempt to get back to normal activity brings the pain right back.
An ankle sprain that isn't healing as expected doesn't automatically mean something serious is wrong. Some sprains simply take longer to recover, especially when the ligament injury is more significant than it first appeared.
Still, ongoing pain, swelling, weakness, instability, or trouble getting back to your usual activities shouldn't be ignored. Sometimes the original injury involves more than a routine sprain. A fracture, high ankle sprain, tendon injury, cartilage damage, or chronic ankle instability can all cause symptoms that linger.
So how can you tell whether your ankle just needs more time—or whether it's worth taking another look?
Key Takeaways
Ankle sprains don't all heal on the same schedule. More significant ligament injuries often take longer than mild sprains.
Look for steady improvement in pain, swelling, movement, strength, and function rather than focusing only on how many days or weeks have passed.
Ongoing symptoms can sometimes be caused by a fracture, high ankle sprain, tendon injury, cartilage damage, or a more severe ligament injury.
If your ankle repeatedly gives way, chronic ankle instability may be part of the problem.
Most ankle sprains don't require an MRI or other advanced imaging.
Physical therapy can help rebuild motion, strength, balance, and stability after a sprain.
If your recovery has stalled, your symptoms are getting worse, or you're still struggling to walk or return to normal activities, another evaluation may be worthwhile.
How Long Should an Ankle Sprain Take to Heal?
There's no single recovery timeline for an ankle sprain.
A mild injury may start feeling noticeably better fairly quickly. More significant ligament damage can take weeks or longer. Recovery may also be slower if several structures were injured at once or if you've sprained the same ankle in the past.
That's why the calendar only tells part of the story.
What's more useful is looking at the overall direction of your recovery. Pain should gradually become less noticeable. Swelling should settle. Walking should get easier, and your strength and motion should start coming back.
That doesn't mean every day will be better than the one before it. A long day on your feet or an increase in activity may temporarily leave the ankle feeling more sore. What matters is that, overall, you're continuing to make progress.
Sriya S. Babu, DPM, FACFAS, a board-certified podiatric surgeon at Arthritis & Sports, explains that ankle sprain recovery is better measured by progress than by a fixed timeline: "If an ankle keeps giving way, I don’t want patients to just accept that they have a ‘bad ankle.’ We want to understand why it keeps happening. Is it lingering ligament instability, muscle weakness, impaired balance, or an underlying injury that hasn’t fully healed? Have they tried physical therapy, bracing, or other conservative treatments? Is advanced imaging needed to better understand what’s going on? Once we identify the underlying problem, we can build a treatment plan that addresses the cause and helps restore stability and confidence in the ankle."
What Should Normal Ankle Sprain Recovery Feel Like?
As the ankle heals, you should generally begin to notice:
Less pain with everyday activities
Less swelling
Better range of motion
Improving strength
More confidence when walking
Better balance
Greater tolerance for activity without a major increase in symptoms
It's also normal for the injured ankle to feel stiff, sore, or weaker than the other side for a while.
The bigger concern is when that improvement stops.
When Is an Ankle Sprain Taking Too Long to Heal?
There isn't a specific day or week when an ankle sprain suddenly becomes abnormal.
Instead, pay attention to whether you're still making progress. If the ankle isn't gradually improving, you're unable to walk normally, it repeatedly gives way, or pain returns every time you try to increase your activity, it may be time to have it reassessed.
Sometimes the original sprain was simply more severe than it seemed. Other times, another injury happened along with it.
Why Is My Ankle Sprain Not Healing?
There are several reasons an ankle sprain may seem to be taking too long to heal.
The ligament injury itself may have been more significant than first thought. You may have returned to normal activity before the ankle had regained enough strength and stability. Or another injury—a fracture, tendon problem, high ankle sprain, or cartilage injury—may be contributing to your symptoms.
The important part isn't simply waiting longer. It's understanding why the ankle still hurts or feels unstable and whether additional foot and ankle care may be helpful.
The Ligament Injury May Be More Severe Than It First Seemed
An ankle sprain occurs when one or more ligaments are stretched or torn.
Some sprains involve relatively minor ligament damage. Others involve more extensive tearing, which can lead to greater swelling, weakness, and instability.
Those injuries naturally take longer to recover.
A slower recovery doesn't necessarily mean something was missed during your first evaluation. In some cases, the ankle simply needs more time—and a more structured rehabilitation plan—to fully recover.
You May Have Returned to Activity Before the Ankle Was Ready
One of the tricky things about ankle sprains is that pain can improve before the ankle is actually ready for demanding activity. You might be able to walk around the house without much trouble, for example, while still lacking the strength, balance, and stability you need to run, jump, or change direction.
That makes returning too soon easy.
Rehabilitation after an ankle sprain often includes exercises to restore motion, strength, balance, and proprioception—the body's ability to sense where a joint is in space. If those abilities haven't fully returned, the ankle can remain vulnerable to another sprain.
7 Signs Your Ankle Injury May Be More Than a Simple Sprain
Lingering symptoms don't automatically mean another injury is present. But certain patterns may give your healthcare provider reason to look beyond a routine sprain.
1. Your Pain Isn't Gradually Improving
Pain is expected after an ankle sprain. The key is what happens next.
If the pain remains significant, starts getting worse, or comes right back every time you increase your activity, the ankle may need another evaluation.
Where you feel the pain can also provide useful information. Pain directly over a bone, deep within the ankle, or higher above the joint may point to something different from a typical lateral ankle sprain.
2. You Still Have Trouble Putting Weight on the Ankle
Walking can be uncomfortable after a sprain, particularly in the early stages or after a more significant injury. But if putting weight on the ankle continues to be difficult, it's worth paying attention.
Healthcare providers may look at your ability to bear weight, where the ankle is tender, and other examination findings when deciding whether an X-ray is appropriate.
And one common misconception is worth clearing up: being able to walk does not automatically mean the ankle isn't broken.
3. Your Ankle Keeps Giving Way or Rolling Again
Maybe the ankle feels loose. It might buckle unexpectedly, or you may feel as though it's about to roll when you're walking on uneven ground. That can be a sign of chronic ankle instability.
After a sprain, the ligaments, muscles, and balance systems surrounding the ankle all need time to recover. If stability doesn't fully return, the joint may continue to feel unreliable.
Repeated sprains can add to the problem.
When an ankle continues to feel unstable after a sprain, Dr. Babu says it’s worth looking beyond the idea of simply having a ‘bad ankle’: “If an ankle keeps giving way, I don’t want a patient to simply accept that they have a ‘bad ankle.’ We want to understand whether there is lingering ligament instability, weakness, a balance problem, or another injury contributing to those repeated episodes.”
4. You Have Pain Higher Above the Ankle
Most ankle sprains involve ligaments along the outside of the ankle. A high ankle sprain, also called a syndesmotic injury, is different. It affects the ligaments connecting the tibia and fibula above the ankle joint.
Instead of pain being concentrated around the outer ankle bone, you may feel it higher up. Twisting movements or pushing off the foot may also hurt.
High ankle sprains can take a different course than routine lateral sprains and may need a different approach to treatment.
5. You Have Pain Directly Over a Bone
A twisting injury doesn't always damage just the ligaments. It can also cause a fracture in the ankle or nearby areas of the foot.
At first, the two can look surprisingly similar. Both sprains and fractures may cause swelling, bruising, pain, and difficulty walking. That's one reason symptoms alone aren't always enough to tell them apart.
Pain that remains sharply focused over one area of bone may be one reason your healthcare provider recommends an X-ray.
6. You Feel Catching, Locking, or Deep Pain Inside the Ankle
Sometimes a twisting injury damages the cartilage and bone inside the ankle joint.
One possible injury is an osteochondral lesion of the talus, which affects the cartilage and underlying bone on the surface of the talus.
Symptoms can include:
Deep ankle pain
Ongoing swelling
Catching
Locking
A feeling that something is sticking or moving inside the joint
Continued instability
Those symptoms aren't typical of every ankle sprain and may be a reason for further evaluation.
7. Pain Runs Along the Outside or Back of Your Ankle
Ligaments aren't the only structures that can be injured when the ankle twists. The peroneal tendons, which run behind and along the outside of the ankle, may also be irritated or damaged.
A tendon injury can cause pain behind or below the outer ankle bone. Some people also notice weakness or pain with certain movements of the foot.
Because tendon and ligament injuries can happen at the same time, persistent pain in this area is worth having checked.
What Else Can Be Mistaken for an Ankle Sprain?
Several injuries can look and feel similar to a routine ankle sprain.
Possible problem | Clues that may raise concern | How it differs |
More severe ligament sprain | Persistent swelling, weakness, instability | More extensive ligament damage |
Ankle or foot fracture | Focal bone tenderness, difficulty bearing weight | Injury to bone rather than only ligament |
High ankle sprain | Pain above the ankle, pain with twisting or push-off | Involves the syndesmotic ligaments |
Peroneal tendon injury | Pain behind or outside the ankle, weakness | Involves a tendon rather than only a ligament |
Osteochondral lesion | Deep pain, swelling, catching or locking | Involves cartilage and underlying bone |
Chronic ankle instability | Repeated rolling or giving way | Ongoing instability after the initial injury |
These are clues, not a checklist for diagnosing yourself. Several ankle problems can cause very similar symptoms, which is why an examination matters when recovery isn't going as expected.
When Should I See a Doctor for an Ankle Sprain That Isn't Healing?
Consider having your ankle evaluated if you're no longer making steady progress, you're still struggling to walk normally, or the joint continues to feel weak or unstable.
Symptoms that are getting worse rather than better are another reason to seek care.
Signs That Need Prompt Medical Attention
Depending on the injury, more urgent evaluation may be appropriate if you have:
Severe or rapidly worsening pain
Significant deformity
An open wound
Inability to bear weight
Significant numbness or loss of sensation
A foot that becomes unusually pale, blue, or cold
Significant tenderness directly over a bone after an injury
If you're not sure how quickly you should be seen, contacting a healthcare professional can help you decide on the appropriate next step.
Signs You Should Schedule a Foot and Ankle Evaluation
You may want to make an appointment if:
Your pain isn't gradually improving
Swelling keeps coming back
You're still limping
The ankle repeatedly gives way
Pain returns every time you exercise
You haven't regained normal motion or strength
You notice catching or locking
You've sprained the same ankle several times
Having the ankle evaluated doesn't mean you're headed for surgery or an MRI. Often, the goal is simply to figure out what's holding back your recovery and what can be done to address it.
If you're unsure who should evaluate persistent ankle symptoms, a foot and ankle specialist can assess whether you're dealing with a lingering sprain or another injury.
How Is a Slow-Healing Ankle Sprain Diagnosed?
The evaluation usually starts with a conversation and physical examination. Your foot and ankle specialist may ask how you injured the ankle, where the pain started, where you feel it now, and whether you've had previous sprains. They'll also want to know what you've tried so far and which activities are still giving you trouble.
During the examination, your provider may look at:
Tenderness
Swelling
Range of motion
Strength
Tendon function
Ankle stability
Foot and ankle alignment
How you walk
From there, they can decide whether imaging or another test would add useful information.
When Is an X-Ray Needed for an Ankle Sprain?
Digital X-rays are primarily used to evaluate bones and may be recommended when a fracture or another bony problem is suspected. They don't show ligaments and tendons in the same detail as other imaging studies, but they can reveal fractures or other bony problems that may explain persistent pain.
That doesn't mean everyone who twists an ankle needs one. Your provider may recommend an X-ray based on how the injury happened, where the ankle is tender, whether you're able to bear weight, and what they find on examination.
Do You Need an MRI for an Ankle Sprain?
Usually, no. Most uncomplicated ankle sprains don't require an MRI.
Advanced imaging becomes more useful when the ankle isn't recovering as expected or when the physical examination raises concern for another problem involving the ligaments, tendons, cartilage, or other structures.
Depending on what your provider suspects, other imaging studies may occasionally be considered as well.
The goal isn't to order more testing simply because an ankle still hurts. Imaging is most helpful when there's a specific question to answer and the result may change the treatment plan.
How Is an Ankle Sprain That Isn't Healing Treated?
The treatment depends on what's actually causing the ongoing pain, weakness, or instability.
For one person, the answer may be a more structured rehabilitation program. Someone else may need to temporarily modify activity or use a brace or boot. If another injury is found, that problem may need its own treatment.
Depending on the diagnosis, treatment may include:
Activity modification
Bracing or support when appropriate
Range-of-motion exercises
Strengthening
Balance and proprioception training
Physical therapy
Treatment for an associated fracture or tendon injury
Treatment for cartilage damage
Surgery in selected cases
The goal is bigger than simply making the pain go away. You want enough motion, strength, and stability for the ankle to work well again.
Dr. Babu emphasizes that persistent ankle symptoms should be treated based on their cause, not just how long they’ve been present: “When an ankle isn’t recovering, the first question isn’t ‘Does this patient need surgery?’ It’s ‘Why are the symptoms still there?’ Once we understand the cause, we can build the treatment plan around it.”
Can Physical Therapy Help a Sprained Ankle Heal?
Yes. Physical therapy can play an important role in ankle sprain recovery.
Early in rehabilitation, the focus may be on getting comfortable motion back and reducing stiffness. As the ankle improves, exercises can gradually become more demanding.
Physical therapy may help restore:
Range of motion
Ankle and lower-leg strength
Balance
Proprioception
Stability
Walking and running mechanics
Confidence using the ankle again
For athletes, later stages of rehabilitation may also include movements such as hopping, jumping, cutting, or changing direction. The goal isn't simply to make the ankle comfortable when you're sitting still. It needs to be ready for the activities you actually want—or need—to do.
Does a Lingering Ankle Sprain Need Surgery?
Most ankle sprains do not need surgery.
Surgery may be considered in selected cases when the ankle remains mechanically unstable or when another injury hasn't improved with appropriate nonsurgical treatment. That could include certain ligament, tendon, cartilage, or fracture problems.
Even when ankle symptoms have been around for quite a while, surgery isn't automatically the next step. The decision depends on the diagnosis, how much the problem is affecting your daily life or activities, and what treatments you've already tried.
When Can I Return to Running or Sports After an Ankle Sprain?
Return to sports shouldn't be decided by the calendar alone. What matters is whether the ankle can handle the demands you're about to place on it.
Before you return to running or sports, your healthcare provider or physical therapist may consider:
Pain
Swelling
Range of motion
Strength
Balance
Ankle stability
Your ability to hop or jump
Your ability to speed up and slow down
Your ability to cut or change direction
Whether activity causes a meaningful increase in symptoms afterward
Being able to walk comfortably is a good milestone. It doesn't always mean you're ready to sprint, jump, or make a sharp cut on the field.
Athletes returning to running, cutting, jumping, or competition may benefit from sports medicine care that considers strength, stability, movement quality, and the demands of their sport.
Can an Ankle Sprain Cause Chronic Ankle Instability?
Yes. Some people continue to have weakness or repeated episodes of the ankle giving way after a sprain. This is called chronic ankle instability.
It may develop when the ligaments remain loose or when strength, balance, and neuromuscular control haven't fully recovered. Repeated sprains can make the problem worse.
If your ankle keeps rolling or feels unreliable, don't assume you simply have to live with a “bad ankle.” Treatment may include rehabilitation, bracing, activity changes, and, for selected patients, surgical stabilization.
What Surgical Options Are Available for Chronic Ankle Instability or Pain After an Ankle Sprain?
When an ankle sprain doesn't improve with physical therapy, bracing, or other conservative treatments, surgery may be an option—particularly if the ankle continues to feel unstable or advanced imaging reveals chronic ligament damage or other underlying injuries.
The type of surgery depends on what is causing the ongoing symptoms. Dr. Babu offers several surgical options based on the patient's specific injury, including:
Ankle arthroscopy: A minimally invasive procedure using a small camera to evaluate and treat problems inside the ankle joint, such as scar tissue, inflammation, loose bodies, or cartilage injuries.
Ankle ligament repair (Broström procedure): Repairs and tightens damaged ligaments on the outside of the ankle to help restore stability.
Ligament repair with augmentation: Reinforces repaired ligaments with additional support when appropriate, particularly in patients with poor ligament quality or significant instability. Rebuilds chronically damaged or insufficient ligaments, often using a tendon graft when the existing ligaments cannot be adequately repaired.
Peroneal tendon repair: Addresses tendon tears or damage that may contribute to persistent pain, weakness, or instability along the outside of the ankle.
Syndesmotic repair or stabilization: Treats persistent instability of the ligaments connecting the tibia and fibula, sometimes associated with a high ankle sprain.
Osteochondral lesion repair: Treats injuries involving the cartilage and underlying bone of the talus, which can cause persistent ankle pain, swelling, or catching.
Not every patient needs surgery, and not every procedure is necessary. In some cases, multiple problems may need to be addressed during the same surgery. The goal is to identify the source of the ongoing symptoms, restore ankle stability when needed, and help patients return to their normal activities with greater confidence.

Frequently Asked Questions About an Ankle Sprain Not Healing
Why Is My Ankle Sprain Not Healing?
An ankle sprain may take longer to heal if the ligament injury is more severe, the ankle hasn't regained enough strength or stability, or you returned to activity before recovery was complete. Persistent symptoms can also occur when another injury is present, such as a fracture, tendon problem, high ankle sprain, or cartilage injury.
How Long Is Too Long for an Ankle Sprain to Hurt?
There's no single timeline that applies to every ankle sprain. Mild injuries may improve fairly quickly, while more significant sprains can take weeks or longer. The more useful question is whether your pain, swelling, motion, and function are steadily improving. If that progress has stopped—or your symptoms are getting worse—consider having the ankle evaluated.
Why Does My Ankle Still Hurt Weeks After I Sprained It?
Ongoing pain can come from the original ligament injury, lingering stiffness or weakness, incomplete rehabilitation, or ankle instability. In some cases, another injury may also be contributing, including a fracture, tendon injury, high ankle sprain, or cartilage damage.
How Do I Know if My Ankle Sprain Is Actually a Fracture?
Sprains and fractures can both cause pain, swelling, bruising, and difficulty walking, so symptoms alone may not reliably tell them apart. Significant tenderness directly over a bone or difficulty bearing weight may raise concern. A physical examination and, when appropriate, an X-ray can help determine whether a fracture is present.
Can a Fracture Be Missed After an Ankle Sprain?
Yes. Some fractures can initially look like ankle sprains, particularly after a twisting injury. Persistent pain in one specific area, ongoing difficulty bearing weight, or an ankle that isn't recovering as expected may be reasons to have the injury reassessed.
Do I Need an MRI if My Ankle Sprain Isn't Healing?
Not necessarily. Most straightforward ankle sprains don't require an MRI. Advanced imaging may be considered when recovery isn't progressing normally or when the examination suggests another problem involving the ligaments, tendons, cartilage, or joint.
Why Does My Ankle Keep Giving Way After a Sprain?
Repeated giving way may be a sign of chronic ankle instability. The ligaments may remain loose, or the ankle may not have fully regained its strength, balance, and neuromuscular control. Rehabilitation can often help, although persistent mechanical instability may need further evaluation.
Can Physical Therapy Help an Ankle Sprain That Still Hurts?
Yes. Physical therapy can help restore motion, strength, balance, stability, and confidence after an ankle sprain. A therapist can also guide a gradual return to walking, running, work, or sports based on how your ankle is responding.
