Chronic lateral ankle pain
Recurring or persistent (chronic) pain on the outer (lateral) side of the ankle often develops after an injury, such as a sprained ankle. However, several other conditions may also cause chronic ankle pain.
Signs and symptoms
• Pain, usually on the outer side of the ankle—The pain may be so intense that you have difficulty walking or participating in sports. In some cases, the pain is a constant, dull ache.
The most common cause for a persistently painful ankle is incomplete healing after an ankle sprain. When you sprain your ankle, the connecting tissue (ligament) between the bones is stretched or torn. Without thorough and complete rehabilitation, the ligament or surrounding muscles may remain weak, resulting in recurrent instability. As a result, you may experience additional ankle injuries.
Other causes may include:
Evaluation and diagnosis
The first step in identifying the cause of chronic ankle pain is taking a history of the condition. Your doctor may ask you: Have you previously injured the ankle? If so, when? What kind of treatment did you receive? How long have you had the pain? Are there times when the pain worsens or disappears?
Because there are so many potential causes for chronic ankle pain, your doctor may do a number of tests to pinpoint the diagnosis, beginning with a physical examination. Your doctor will feel for tender areas, look for signs of swelling, and assess range of motion and flexibility. Your doctor may also test the sensation of the nerves and may administer a shot of local anesthetic to help pinpoint the source of the symptoms.
Your doctor may order several X-ray views of your ankle joint. You may also need to get X-rays of the other ankle so the doctor can compare the injured and noninjured ankles. In some cases, additional tests such as a bone scan, computed tomography (CT) scan or magnetic resonance image (MRI) may be needed.
Treatment will depend on the final diagnosis and should be personalized to your individual needs. Both conservative (nonoperative) and surgical treatment methods may be used. Conservative treatments include:
If your condition requires it, or if conservative treatment doesn’t bring relief, your doctor may recommend surgery. Many surgical procedures can be done on an outpatient basis. Some procedures use arthroscopic techniques; others require open surgery. Rehabilitation may take 6 to 10 weeks to ensure proper healing. Surgical treatment options include: removing (excising) loose fragments, cleaning (debriding) the joint or joint surface and repairing or reconstructing the ligaments or transferring tendons.
Almost half of all people who sprain their ankle once will experience additional ankle sprains and chronic pain. You can help prevent chronic pain from developing by following these simple steps:
