Bursitis is defined as inflammation of a bursa. Humans have approximately 160 bursae. These are saclike structures between skin and bone or between tendons, ligaments, and bone. The bursae are lined by synovial tissue, which produces fluid that lubricates and reduces friction between these structures.
Repetitive, vigorous movement, strenuous and unaccustomed activities that put pressure on a joint, or a blow or other injury can bring on bursitis. The cause can vary depending on where the bursitis occurs. In the shoulder, for example, it can be brought on by excessive strain, such as from serving in tennis. Kneeling on a hard floor can cause bursitis of the knee, and similarly, repeatedly resting the elbow on a hard surface (such as a desk) can cause bursitis in that joint. Arthritis, gout, and certain infections can also contribute to the problem. Bursitis, in fact, may signal the onset of arthritis. While getting older isn't a cause of bursitis, older people, especially older athletes, are more likely to develop the condition.
The main symptom of heel bursitis is pain. You may experience pain in your heel when you walk or run. There may also be pain if the area is touched or if you stand on your tiptoes. In addition to pain, the area may appear red and warm, which are both signs of inflammation. Even if you have these symptoms, only a doctor can determine if you have bursitis of the heel. Your doctor will use these symptoms along with a general exam to determine if you are suffering from bursitis of the heel.
To begin with, your doctor will gather a medical history about you and your current condition and symptoms. He/she will inquire about the level of your heel pain, the how long you have had the symptoms and the limitations you are experiencing. Details about what and when the pain started, all are very helpful in providing you with a diagnoses of your ankle / heel.
Non Surgical Treatment
Many cases of retrocalcaneal and retroachilles bursitis can be treated effectively at home. One of the most important factors is eliminating shoe gear that presses against the back of the heel. Comfortable, supportive footwear and frequently resting the foot will minimize friction at the heel and give the inflammation a chance to subside. These steps, along with other methods to alleviate swelling, such as non-steroidal anti-inflammatory drugs (NSAIDs, e.g., ibuprofen), icing the heel, and elevating the foot, are usually successful in treating retrocalcaneal bursitis.
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).
Do not run if you have pain. When you begin running again, avoid running fast uphill or downhill until the tendon is fully healed. Start exercising when caregivers say that it is OK. Slowly start exercise such as bicycling when caregivers say it is OK. When doing exercises that put pressure on the ankles, such as running or walking, exercise on flat, even surfaces. Avoid doing these exercises on very hard surfaces such as asphalt or concrete. Stretch before exercising. Always warm up your muscles and stretch gently before exercising. Do cool down exercises when you are finished. This will loosen your muscles and decrease stress on your heel. Wear heel protectors. Use soft foam or felt heel pads (wedges or cups) to help decrease pressure against your heel. Ask your caregiver which heel pads are the best for you. Wear well-fitting shoes. Buy running or exercise shoes that support and fit your feet well. Do not wear low-cut shoes. Talk to your caregiver or go to a special exercise footwear store to get well-fitting athletic shoes. Ask your caregiver if you should wear specially-made shoe inserts called orthotics (or-THOT-iks). Orthotics can line up your feet in your shoes to help you run, walk and exercise correctly.
