Signs Your Ankle Sprain Isn’t Healing the Way It Should

Ankle sprains are common injuries. Because they happen so frequently, many people assume they can simply rest for a few days and return to their usual routine.

That may be enough for a mild sprain. However, an ankle that remains painful, swollen, stiff, or unstable may need more than time and home care.

Recovery does not happen at the same pace for everyone. A mild ligament injury may improve within a couple of weeks, while a more severe sprain can take several weeks or longer. [1][2] The important question is not whether your ankle feels completely normal right away — it is whether your symptoms and function are gradually improving.

When an ankle sprain is not healing as expected, an orthopedic evaluation can determine whether the ligament injury is more serious than initially thought or whether another condition is causing your symptoms.

How Long Does an Ankle Sprain Take to Heal?

An ankle sprain occurs when one or more of the ligaments supporting the joint are stretched or torn. Recovery time depends on the severity of the ligament damage, the number of ligaments involved, whether another structure was injured, previous ankle sprains, your age and general health, how quickly appropriate treatment begins, and whether you complete a rehabilitation program. [1][5]

A mild sprain may begin improving within several days and recover within a few weeks. A moderate or severe sprain often requires a longer recovery period. Some swelling or stiffness can linger even while the ligament is healing — that does not automatically mean something is wrong. However, symptoms should generally trend in the right direction: pain should become less intense, walking should become easier, and the ankle should gradually regain motion and stability. In studies following patients after ankle sprains, a significant proportion still report pain or instability months later — most often after more severe injuries or incomplete rehabilitation. [2]

Signs Your Ankle Sprain May Not Be Healing Properly

Your pain is not improving. Pain is expected after a sprain, but it should gradually become less intense. Pain that remains unchanged or worsens may indicate a more significant ligament tear or another injury — and pain in a very specific area of bone raises concern for a fracture. [4] Pain that improves with rest but returns as soon as you begin walking or exercising may mean the ankle is not ready for that level of activity.

Swelling remains significant. Swelling can last longer than many people expect. The concern is not that some swelling remains — it is swelling that is not decreasing, or that repeatedly becomes severe after ordinary activity. Ongoing swelling may reflect continued ligament irritation, joint inflammation, cartilage damage, or returning to activity too quickly.

The ankle keeps giving way. Your ankle should feel more stable as it heals. If it repeatedly rolls, buckles, or feels as though it cannot support you, the injured ligaments may not be providing enough stability — and this can develop into chronic ankle instability, with repeated sprains, difficulty on uneven surfaces, and a constant sense that the ankle cannot be trusted. [3] Learn more about recurrent ankle instability and why repeated sprains should not be ignored.

You still cannot bear weight. Walking is often painful immediately after an injury, but the ability to bear weight should gradually improve. If you still cannot take several steps, or pain becomes severe whenever you put weight on the foot, you should be evaluated — a fracture, severe ligament injury, high ankle sprain, or tendon injury may be present. Inability to bear weight is one of the standard criteria physicians use when deciding whether an X-ray is needed. [4]

Your range of motion is not returning. Stiffness is common after swelling and reduced activity. Over time you should regain the ability to point the foot, bring the toes toward the shin, and move the ankle with less restriction. Limited motion that does not improve can alter your walking pattern and force compensation through the knee, hip, or opposite leg.

You feel catching, locking, or deep joint pain. Pain from a typical lateral sprain is felt around the injured ligaments on the outside of the ankle. Deep pain inside the joint, catching, or locking may suggest injury to the cartilage or underlying bone — an osteochondral lesion of the talus can occur during the original injury, may not be visible on standard X-rays, and sometimes requires MRI. [3]

You have numbness, tingling, or changes in the foot. These are not typical signs of routine healing. They may indicate nerve irritation, severe swelling, or another injury. Changes in skin color, unusual coolness, or loss of sensation require prompt medical evaluation.

Conditions That Can Be Mistaken for an Ankle Sprain

Condition	How it differs from regular sprain	Clues
Ankle Fracture	Both cause pain, bruising, swelling, and difficulty walking. A fracture is more likely with tenderness directly over a bone, inability to bear weight, visible deformity, or severe non-improving pain. X-rays determine whether a bone is broken. [4]	Bone tenderness; cannot take 4 steps
High ankle (syndesmotic) sprain	Injury to the ligaments connecting the tibia and fibula above the ankle joint, often when the foot stays planted while the leg rotates. Heals more slowly than lateral sprains; pain above the ankle, worse with rotation or push-off.	Pain above the joint; rotation pain
Tendon Injury	Peroneal tendon injuries cause pain along the outside of the ankle; Achilles injuries cause pain at the back of the ankle and affect push-off. Both can be strained or torn in the same fall or twist.	Pain along a tendon line; weak push-off
Cartilage or bone injury (osteochondral lesion)	The force that sprains an ankle can damage the joint surface of the talus or bruise the bone beneath it. Persistent swelling, deep pain, catching, or discomfort that returns whenever activity increases; often invisible on X-ray. [3]	Deep joint pain; catching/locking

Why Incomplete Rehabilitation Can Cause Ongoing Problems

An ankle may stop hurting before it has fully regained strength, balance, and stability — which leads people to return to exercise before the joint is ready. A complete recovery involves more than waiting for swelling to disappear. Rehabilitation may need to address ankle range of motion, calf and lower-leg strength, balance and proprioception, walking mechanics, agility and directional control, and sport-specific movements. Skipping these steps leaves the ankle vulnerable to another sprain — and structured exercise-based rehabilitation measurably reduces re-sprain risk. [5]

Once a fracture or other associated injury has been ruled out, a progressive rehabilitation program can restore function. See what that process may involve in our companion article, The Rehab Timeline for Ankle Sprains: Week by Week.

When Should You See an Orthopedic Ankle Specialist?

Consider scheduling an evaluation if:

• Pain or swelling is not improving
• You cannot comfortably bear weight
• The ankle repeatedly gives way
• Motion remains significantly limited
• You have returned to activity but symptoms keep coming back
• You have suffered several ankle sprains
• You are unsure whether the injury is a sprain or fracture

Seek prompt medical care for a visible deformity, an open wound, severe worsening pain, loss of sensation, or signs of infection such as increasing redness, warmth, or fever. An ankle specialist can examine the joint, assess ligament stability, and determine whether imaging is needed. X-rays rule out fracture; an MRI or other imaging may be considered when symptoms suggest significant ligament damage, cartilage injury, or tendon involvement. [3][4]

Treatment for an Ankle Sprain That Is Not Healing

Treatment depends on the cause of the ongoing symptoms. Your plan may include temporary activity modification; a brace, walking boot, or other supportive device; medication for pain and inflammation when appropriate; physical therapy; balance and stability training; gradual return-to-activity testing; and surgery in selected cases involving severe damage or persistent instability.

Most ankle sprains can be treated without surgery — the goal is to protect the injured tissue while restoring motion, strength, and confidence in the joint. [5] Learn more about ankle sprain treatment at New York Bone & Joint Specialists.

Do Not Let a Lingering Sprain Become a Long-Term Problem

An ankle sprain may seem minor, but an injury that does not heal correctly can affect the way you walk, exercise, and move through daily life — and increase your risk of repeated sprains and chronic instability. [3] If your ankle is still painful, swollen, weak, or unreliable, do not keep testing it and hoping the problem resolves on its own. The orthopedic team at New York Bone & Joint Specialists can identify why your ankle sprain is not healing and create a treatment plan based on the severity of your injury and your activity goals.

Frequently Asked Questions

How do I know if my ankle sprain isn’t healing properly?

A healing sprain shows steady week-over-week improvement — warning signs include pain or swelling that plateaus or worsens, repeated giving way, inability to bear weight, motion that isn’t returning, catching or deep joint pain, and numbness or tingling. Some lingering swelling and stiffness is normal while the ligament heals. What matters is the trend: an ankle that stops improving deserves an examination to rule out a more severe ligament injury or a different diagnosis. [1][2]

How long should an ankle sprain take to heal?

Mild ankle sprains usually improve within days and recover within a few weeks; moderate and severe sprains often take six weeks or longer, and high ankle sprains typically heal more slowly than standard lateral sprains. Recovery also depends on prior sprains, how quickly treatment began, and whether rehabilitation was completed. Studies show many patients still report symptoms months after a sprain — most often when the injury was severe or rehab stopped early. [1][2]

Could my “ankle sprain” actually be a fracture?

Yes — fractures and sprains can both cause pain, bruising, swelling, and difficulty walking, and a fracture is more likely when there is tenderness directly over a bone or you cannot bear weight for several steps. Those two findings are the core of the validated Ottawa ankle rules physicians use to decide when X-rays are needed. Pain that persists after a “sprain” is a common presentation of a missed fracture, so get an X-ray if these signs are present. [4]

Why does my ankle keep giving way after a sprain?

Repeated giving way usually means the injured ligaments and the surrounding muscles have not regained enough stability and proprioception — the beginning of chronic ankle instability. Each additional sprain damages the ligaments further. Balance and strengthening rehabilitation resolves many cases; ligament repair or reconstruction is reserved for persistent instability despite therapy. Repeated sprains should be evaluated, not accepted. [3][5]

What is a high ankle sprain and why does it take longer?

A high ankle sprain injures the syndesmosis — the ligaments connecting the tibia and fibula above the ankle joint — and typically heals more slowly than a standard lateral sprain. It often occurs when the foot stays planted while the leg rotates. Pain is felt above the ankle and worsens with rotation or push-off. Because it destabilizes the joint differently, it needs specific evaluation and sometimes longer protection.

Do I need an MRI for an ankle sprain that isn’t healing?

Not always — X-rays rule out fracture first, and MRI is added when symptoms suggest significant ligament damage, cartilage injury (osteochondral lesion), or tendon involvement that X-rays cannot show. Deep joint pain, catching, locking, or swelling that rebounds with every increase in activity are the symptoms that most often justify advanced imaging after a stalled recovery. [3]

Can a sprained ankle heal without surgery?

Yes — the large majority of ankle sprains, including severe ones, are treated successfully without surgery using protection, progressive rehabilitation, and balance training. Surgery is reserved for selected cases: persistent instability despite complete rehabilitation, certain associated fractures, tendon tears, or cartilage lesions. Completing rehabilitation is the single most important step in preventing re-sprain. [5]
