Retrocalcaneal bursitis is sometimes difficult to differentiate from Achilles tendinitis, at least symptomatically. Both are most uncomfortable during the push-off phase of gait, are most severely painful in the morning and with walking after sitting for a period of time, and generally worsen with activity. Most practitioners make the distinction between the two simply on the basis of location of pain and tenderness. Generally, Achilles tendinitis is felt an inch or two higher than this form of bursitis.
Bursitis of the Achilles tendon is caused by the irritation and inflammation of the retrocalcaneal bursa, a small fluid-filled sac located in the back of the ankle that acts as a cushion and lubricant for the ankle joint. Possible causes of Achilles tendon bursitis include aging, Factors related to the aging process, including the onset of rheumatoid arthritis and gout, can deteriorate the bursa. Overuse of ankle. Excessive walking, uphill running, jumping, and other aggressive exercise regimens, especially without proper conditioning, can cause irritation to the bursa. Trauma. Sudden injury to the ankle joint, or trauma caused by rigid or improperly fitted shoes, can increase the chances of developing bursitis.
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.
Your health care provider will take a history to find out if you have symptoms of retrocalcaneal bursitis. Examining your ankle can find the location of the pain. The physician will look for tenderness and redness in the back of the heel. The pain may be worse when the doctor bends the ankle upward (dorsiflex). Or, the pain may be worse when you rise on your toes. You will not usually need imaging studies such as x-ray and MRI at first. If the first treatment does not improve the symptoms, your health care provider may recommend these tests. MRI may show inflammation.
Non Surgical Treatment
In addition to R.I.C.E., there are a number of other treatments to reduce swelling and any associated pain or discomfort due to heel bursitis. Orthotics or change of footwear. Wearing an orthotic device such as a heel insert can encourage better mechanics in the foot and reduce irritation of the retrocalcaneal bursa. Some people do not need special orthotics but simply need to stop wearing shoes with rigid heel and ankle construction and instead wear more supportive, comfortable shoes. Shoes with an "Achilles notch," a groove in the collar at the back of the shoe to protect the Achilles tendon, can be particularly helpful. (Almost all running shoes are designed with an Achilles notch.) Stretching and physical therapy. Stretching the Achilles tendon often helps alleviate pain. Once the pain is resolved it is important for the patient to continue a regular stretching program. Regular stretching reduces the chance of recurrence.
Bursectomy is a surgical procedure used to remove an inflamed or infected bursa, which is a fluid-filled sac that reduces friction between tissues of the body. Because retrocalcaneal bursitis can cause chronic inflammation, pain and discomfort, bursectomy may be used as a treatment for the condition when it is persistent and cannot be relived with other treatments. During this procedure, a surgeon makes small incisions so that a camera may be inserted into the joint. This camera is called an arthroscope. Another small incision is made so that surgical instruments can be inserted to remove the inflamed bursa.
