How to Know If Your Ankle Sprain Isn’t Healing

An ankle sprain can happen suddenly, but recovery may take several weeks or longer depending on the severity of the injury. While a mild sprain often improves with proper care and rehabilitation, persistent pain, swelling, stiffness, weakness, or instability may indicate that the ankle is not healing as expected.

The recovery time depends on the severity of the ligament injury. A mild Grade 1 sprain may improve within a few weeks, while a Grade 2 or Grade 3 sprain can take several weeks to months to recover.

Recovery can also be affected by the severity of the injury, activity level, treatment, and rehabilitation. If symptoms are not gradually improving, a professional evaluation may be needed to determine why recovery is taking longer.

1. Persistent or Worsening Pain

Pain is common immediately after an ankle sprain. However, pain that continues longer than expected, becomes worse, or returns whenever you increase your activity may indicate that the injury has not completely healed.

2. Swelling That Keeps Coming Back

Ankle swelling should generally reduce as the injury heals. If swelling remains significant or repeatedly returns after walking, exercising, or standing for long periods, your ankle may need further evaluation.

3. Ongoing Weakness or Ankle Instability

Persistent weakness or instability can occur when the injured ligaments and surrounding muscles have not regained adequate strength and stability. You may notice that the ankle feels unstable while walking or that you repeatedly roll the same ankle during normal activities. Incomplete rehabilitation can also contribute to ongoing ankle instability.

4. Limited Ankle Movement

Difficulty moving your ankle normally or persistent stiffness can indicate that recovery is incomplete. Reduced ankle movement may also affect your walking pattern and place additional stress on other joints and muscles.

5. Difficulty Bearing Weight

If you continue to limp or cannot comfortably put your full weight on the injured foot after the initial recovery period, do not ignore the symptom.

Difficulty bearing weight can occur with a more significant sprain or an associated injury that may need further assessment.

Several factors can delay recovery, including returning to sports or strenuous activities too soon, not allowing enough time for healing, or not completing rehabilitation.

Persistent symptoms may also be related to another injury, such as a fracture, tendon injury, cartilage damage, high ankle sprain, or a more significant ligament injury.

A clinical examination can help identify the underlying cause and determine whether imaging or other treatment may be appropriate.

Medical evaluation is particularly important if you have severe or persistent pain, significant swelling, difficulty bearing weight, numbness, an obvious deformity, or repeated ankle instability.

If your symptoms are not gradually improving, an evaluation by a foot and ankle specialist can help determine whether the sprain is healing properly or whether another injury is contributing to your symptoms.

Dr. Nrutik Patel, Consultant Foot & Ankle Surgeon at Olwen Hospital, Ahmedabad, provides evaluation and treatment for ankle injuries, ligament problems, sports injuries, and other foot and ankle conditions. Treatment depends on the severity and cause of the problem and may include rehabilitation, medication, activity modification, or other non-surgical approaches. Surgery may be considered only in selected cases involving severe or persistent injuries.

For persistent ankle pain, instability, or a sprain that is not improving as expected, consult a foot and ankle specialist.

An ankle sprain that continues to cause pain, swelling, stiffness, weakness, or instability should not be ignored. These symptoms can sometimes indicate incomplete healing or an associated injury.

An appropriate evaluation can help identify the cause of persistent symptoms and determine the right treatment approach.
