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.
There are several factors which can lead to a person developing retrocalcaneal bursitis. In athletes, especially runners, overtraining, sudden excessive increase in running mileage may lead to retrocalcaneal bursitis. Tight or ill-fitting shoes can be another causative factor as they can produce excessive pressure at the back of the heel due to restrictive heel counter. A person with an excessively prominent posterosuperior aspect of the heel bone (Haglund deformity) may also have a higher predisposition to retrocalcaneal bursitis. In such individuals, pain would be reproduced when the ankle goes into dorsiflexion.
Your heel may feel more sensitive to the cold and ache in cold and damp weather due to impaired circulation. These symptoms are often the result of failure to treat the injury properly from the outset and overicing.
Gram stain. A lab test called a Gram stain is used to determine if certain troublesome bacteria are present. Not all bacteria can be identified with a Gram stain, however, so even if the test comes back negative, septic bursitis cannot be completely ruled out. White blood cell count. An elevated number of white blood cells in the bursa’s synovial fluid indicates an infection. Glucose levels test. Glucose levels that are significantly lower than normal may indicate infection.
Non Surgical Treatment
Orthotics may assist heel bursitis by providing stability to the heel, reduce any foot functioning abnormalities and provide extra support for the feet. The orthotic achieves this by maintaining correct foot posture, therefore facilitating normal functioning of the Achilles tendon. Icing the back of the heel post activity for temporary relief. Non-steroidal anti-inflammatory medication such as ibuprofen can reduce inflammation of the bursa. Stretching of the calf muscle may reduce the pulling on the heel by the Achilles tendon. Shoes that have an elevated heel may reduce pulling on the heel from the Achilles tendon. Resting the painful heel may reduce inflammation and pain. Surgical removal of the painful bursa is a last resort treatment when all other treatments have failed.
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.
