A lesser known type of heel pain is a condition called Bursitis of the Heel. A bursa is a fluid-filled sac that cushions the muscles, tendons and bones in our joints. It helps keep them from rubbing against each other and reduces friction in the areas around the joints. Bursitis is Latin for inflammation of the bursa. Repeated movement and pressure on the bursa can cause it to swell and become inflamed. Trauma, infection or crystal deposits can also cause Bursitis. The joints that are usually affected by bursitis are the large joints such as the shoulder, hip and knee but in some cases also the back of the heel.
The causes and risk factors of retrocalcaneal bursitis are listed below. Identifying the underlying reason the bursa is inflamed will help set a course for treatment. Repetitive use of the ankle. Retrocalcaneal bursitis is often caused by frequent "mini-traumas." These mini-traumas are often due to excessive walking, jumping, or running. Running uphill, which causes the foot to flex considerably, can be especially irritating to the retrocalcaneal bursae. People who suddenly intensify their exercise programs without adequate stretching and muscle conditioning may get retrocalcaneal bursitis. In general, it is often associated with over use of the Achilles attachment, the area where the Achilles tendon fibers attach to the heel.
Common signs and symptoms associated with infracalcaneal bursitis include redness under the heel. Pain and swelling under the heel. Pain or ache in the middle part of the underside of the heel. Heel pain or discomfort that increases with prolonged weight-bearing activities.
Your doctor will check for bursitis by asking questions about your past health and recent activities and by examining the area. If your symptoms are severe or get worse even after treatment, you may need other tests. Your doctor may drain fluid from the bursa through a needle (aspiration) and test it for infection. Or you may need X-rays, an MRI, or an ultrasound.
Non Surgical Treatment
Rest, ice, and anti-inflammatory medication will help with pain and swelling. Physical therapy can help stretch the Achilles to relieve any impingement. Also, a switch to properly-fitting shoes will help to prevent the condition from worsening or recurring. You might also find relief with shoe inserts such as heel cups or padding. If you have tried these measures, yet symptoms remain severe and continue to progress, surgical intervention is a possibility. Calcaneal bursitis surgery consists of excision or removal of the inflamed tissues and resection of the boney prominence. Debridement of the affected area near the Achilles may also be performed, as well as repair of the Achilles if the condition has gone so far that the tendon ruptures.
Surgery to remove the damaged bursa may be performed in extreme cases. If the bursitis is caused by an infection, then additional treatment is needed. Septic bursitis is caused by the presence of a pus-forming organism, usually staphylococcus aureus. This is confirmed by examining a sample of the fluid in the bursa and requires treatment with antibiotics taken by mouth, injected into a muscle or into a vein (intravenously). The bursa will also need to be drained by needle two or three times over the first week of treatment. When a patient has such a serious infection, there may be underlying causes. There could be undiscovered diabetes, or an inefficient immune system caused by human immunodeficiency virus infection (HIV).
