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.
Overuse of the ankle joint may cause irritation of the bursa such as excessive walking, running or jumping. Poor biomechanics and foot function may ultimately lead to heel bursitis due to pulling on the back of the heel by the Achilles tendon.
A sudden increase in physical activity without adequate rest may result in heel bursitis. Excessive standing and walking bare foot on hard surfaces.
Pain at the back of the heel, especially with jumping, hopping, tip-toeing, walking or running uphill or on soft surfaces. If tendonitis is also present, the pain can radiate away from the bursa. Direct pressure on the bursa will exacerbate the pain and should be avoided if possible. Tenderness and swelling which might make it difficult to wear certain shoes on the feet. As the bursa becomes more inflamed you will experience swelling and warmth. In severe cases, the bursa will appear as a bump, called a "pump bump", and is usually red, and extremely tender. Swelling can cause difficulties moving as the range of motion in the ankle can be affected. Limping due to the pain may occur. If you press on both sides of the inflamed heel, there may be a firm spongy feeling. Weakness in the tendons and muscles surrounding the bursa can develop as the pain worsens and the inflammation in the area spreads. Possibly a fever if you are suffering from septic bursitis (You will need to see a doctor for medication to get rid of the infection). Pain at the back of the heel makes it difficult to continue wearing shoes, especially high heels with straps or shoes that don't fit properly.
When you are experiencing Achilles pain at the back of your heel, a visit to the doctor is always recommended. Getting a proper diagnosis is important so you can treat your condition correctly. A doctor visit is always recommended.
Non Surgical Treatment
With posterior Achilles tendon bursitis, treatment is aimed at reducing the inflammation and adjusting the foot's position in the shoe to relieve pressure and motion on the back of the heel. Foam rubber or felt heel pads can be placed in the shoe to eliminate pressure by elevating the heel. Placing protective gel padding over the painful bursa or stretching the back part of the shoe and placing padding around the inflamed bursa may help. Sometimes a special shoe, such as a running shoe designed to stabilize the midsole heel, devices placed in the shoe (orthoses), or both can help to control abnormal foot and heel motion contributing to the posterior heel irritation. Other shoes have padding that reduces irritation to the posterior heel and Achilles tendon.
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.
