Bursitis is defined as inflammation of a bursa. Humans have approximately 160 bursae. These are saclike structures between skin and bone or between tendons, ligaments, and bone. The bursae are lined by synovial tissue, which produces fluid that lubricates and reduces friction between these structures.
A bursa acts as a cushion and lubricant between tendons or muscles sliding over bone. There are bursas around most large joints in the body, including the ankle. The retrocalcaneal bursa is located in the back of the ankle by the heel. It is where the large Achilles tendon connects the calf muscles to the heel bone. Repeated or too much use of the ankle can cause this bursa to become irritated and inflamed. Possible causes are too much walking, running, or jumping. This condition is usually linked to Achilles tendinitis. Sometimes retrocalcaneal bursitis may be mistaken for Achilles tendinitis. Risks for this condition include starting an aggressive workout schedule, or suddenly increasing activity level without the right conditioning.
Medical experts strongly recommend that you consult a doctor if you have any of the symptoms below. Disabling joint pain that prevents you from doing your daily activities. Pain that lasts for more than two weeks. Excessive swelling, redness, bruising or a rash around the painful joint. Sharp or shooting pain, especially when you exercise or do something more strenuous. A fever. Any of the above could be a sign of infection, a condition such as arthritis or a more serious injury such as a tendon tear that may require medical attention.
Bursitis is usually diagnosed after a careful physical examination and a full review of your medical history. If you garden and spend a lot of time on your knees, or if you have rheumatoid arthritis, tell your doctor, this information can be very helpful. During the physical exam, he or she will press on different spots around the joint that hurts. The goal is to locate the specific bursa that is causing the problem. The doctor will also test your range of motion in the affected joint. Other tests usually aren?t required to diagnose bursitis, but your doctor may suggest an MRI, X-ray or ultrasound to rule out other potential causes of pain.
Non Surgical Treatment
Many cases of retrocalcaneal bursitis can be resolved with self-care that is focused on reducing inflammation and eliminating activities or positions that aggravate the bursa. Some cases, however, may become more serious and require more medical interventions. Rarely, surgery is needed. Following the R.I.C.E. formula, or Rest, Ice, Compression, and Elevation, is often sufficient to treat aseptic bursitis. Rest. People with retrocalcaneal bursitis should avoid activities that irritate the bursa, such as jogging or excessive walking. Ice. Applying a cold compress to the back of the ankle for about 20 minutes two or three times a day may help alleviate symptoms and decrease swelling. Compression. An elastic medical bandage (e.g. Ace? bandage) wrapped around the affected heel and ankle can help control swelling. Elevating the affected heel. Sitting down with the leg elevated on a stool or lying down with the foot elevated on a pillow can help reduce blood flow to the area, thereby reducing inflammation.
Surgery is rarely done strictly for treatment of a bursitis. If any underlying cause is the reason, this may be addressed surgically. During surgery for other conditions, a bursa may be seen and removed surgically.
