Bursitis means inflammation of a bursa, a sac that lines many joints and allows tendons and muscles to move easily when the joint is moving. In the heel, bursitis may cause pain at the underside or back of the heel. In some cases, heel bursitis is related to structural problems of the foot that cause an abnormal gait (way of walking). In other cases, wearing shoes with poorly cushioned heels can trigger bursitis.
Inflammation of the bursa causes synovial cells to multiply and thereby increases collagen formation and fluid production. A more permeable capillary membrane allows entrance of high protein fluid. The bursal lining may be replaced by granulation tissue followed by fibrous tissue. The bursa becomes filled with fluid, which is often rich in fibrin, and the fluid can become hemorrhagic. One study suggests that this process may be mediated by cytokines, metalloproteases, and cyclooxygenases.
The following are the most common symptoms of bursitis. However, each individual may experience symptoms differently. Bursitis can cause pain, localized tenderness, and limited motion. Swelling and redness may occur if the inflamed bursa is close to the surface (superficial). Chronic bursitis may involve repeated attacks of pain, swelling, and tenderness, which may lead to the deterioration of muscles and a limited range of motion. The symptoms of bursitis may resemble other medical conditions or problems. Always consult your doctor for a diagnosis.
After you have described your foot symptoms, your doctor will want to know more details about your pain, your medical history and lifestyle, including whether your pain is worse at specific times of the day or after specific activities. Any recent injury to the area. Your medical and orthopedic history, especially any history of diabetes, arthritis or injury to your foot or leg. Your age and occupation. Your recreational activities, including sports and exercise programs. The type of shoes you usually wear, how well they fit, and how frequently you buy a new pair.
Non Surgical Treatment
Physiotherapy treatment is vital to hasten the healing process, ensure an optimal outcome and reduce the likelihood of injury recurrence in all patients with retrocalcaneal bursitis. Treatment may comprise soft tissue massage (particularly to the calf muscles), joint mobilization (of the ankle, subtalar joint and foot), dry needling, electrotherapy (e.g. ultrasound), stretches, the use of heel wedges, the use of crutches, ice or heat treatment, arch support taping, the use of a compression bandage, exercises to improve strength, flexibility, balance and core stability, education, anti-inflammatory advice, activity modification advice, biomechanical correction (e.g. the use of orthotics), footwear advice, a gradual return to activity program.
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).
It isn’t always possible to avoid the sudden blow, bump, or fall that may produce bursitis. But you can protect your body with measures similar to those that protect you from other kinds of overuse injuries, such as tendinitis. Keep yourself in good shape. Strengthening and flexibility exercises tone muscles that support joints and help increase joint mobility. Don?t push yourself too hard (or too long). If you?re engaged in physical labor, pace yourself and take frequent breaks. If you?re beginning a new exercise program or a new sport, work up gradually to higher levels of fitness. And anytime you?re in pain, stop. Work on technique. Make sure your technique is correct if you play tennis, golf, or any sport that may strain your shoulder. Watch out for ?elbow-itis.? If you habitually lean on your elbow at your work desk, this may be a sign that your chair is uncomfortable or the wrong height. Try to arrange your work space so that you don?t have to lean on your elbow to read, write, or view your computer screen. Take knee precautions. If you have a task that calls for lots of kneeling (for example, refinishing or waxing a floor), cushion your knees, change position frequently, and take breaks. Wear the right shoes. High-heeled or ill-fitting shoes cause bunions, and tight shoes can also cause bursitis in the heel. Problems in the feet can also affect the hips. In particular, the tendons and bursae in the hips can be put under excessive strain by worn-down heels. Buy shoes that fit and keep them in good repair. Never wear a shoe that?s too short or narrow. Women should save their high heels for special occasions only. Avoid staying in only one position for too long. Get up and walk around for a while or change positions frequently.
