Bursitis happens when the bursa is inflamed. The burse acts as a cushion between bones, tendons, joints and muscles, bursae are fluid-filled sacs (the plural of bursa is bursae). People with bursitis will feel pain at the site of inflammation. The medical word "bursa" comes from the Latin bursa, meaning a purse, which is what a bursa resembles.
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.
Patients with this condition typically experience pain at the back of the ankle and heel where the Achilles tendon attaches into the heel bone. Pain is typically experienced during activities requiring strong or repetitive calf contractions (often involving end of range ankle movements) such as walking (especially uphill), going up and down stairs, running, jumping or hopping (especially whilst wearing excessively tight shoes). Often pain may be worse with rest after these activities (especially that night or the following morning). The pain associated with this condition may 'warm up' with activity in the initial stages of injury. As the condition progresses, patients may experience symptoms that increase during sport or activity, affecting performance. In severe cases, patients may walk with a limp or be unable to weight bear on the affected leg. Other symptoms may include tenderness on firmly touching the affected bursa and swelling around the Achilles region.
The doctor will discuss your symptoms and visually assess the bones and soft tissue in your foot. If a soft tissue injury is suspected, an MRI will likely be done to view where and how much the damage is in your ankle. An x-ray may be recommended to rule out a bone spur or other foreign body as the cause of your ankle pain. As the subcutaneous bursa is close to the surface of the skin, it is more susceptible to septic, or infectious, bursitis caused by a cut or scrape at the back of the heel. Septic bursitis required antibiotics to get rid of the infection. Your doctor will be able to determine whether there is an infection or not by drawing a small sample of the bursa fluid with a needle.
Non Surgical Treatment
Physical therapy is also used to treat retrocalcaneal bursitis. People with this condition may be instructed to use ice on the heel and ankle several times each day. Ice should be applied for periods of 15 to 20 minutes. Prolonged use of ice is not recommended because it can stop blood flow if left in place for a long period of time. Exercises and stretches for the Achilles tendon can help to relieve some of the pressure on the bursae below the tendons. If physical activity must be limited due to a flare-up of this condition, other exercises can be done to maintain fitness. They include water aerobics and swimming.
Surgery is rarely need to treat most of these conditions. A patient with a soft tissue rheumatic syndrome may need surgery, however, if problems persist and other treatment methods do not help symptoms.
After taking a history and performing a physical examination, your physician may order x-rays to rule out other disorders. Your doctor may administer injections of corticosteroids and a local anesthetic to reduce swelling and ease pain. Also, to reduce swelling, your physician may draw excess fluid from the bursa with a syringe and then tightly wrap and compress the joint with an elastic bandage. In severe, persistent cases surgery to remove the bursa may be necessary. For infectious bursitis, antibiotics will be prescribed.
