A bursa is a fluid-filled sac. There are hundreds of deep and superficial bursae throughout the human body. They are typically located near major joints. Bursae are situated between bone and soft tissues like tendons, ligaments, muscles, and skin. They serve as a cushioning pad to absorb shock. The fluid within the sac is secreted to assist with friction-free movement as the soft tissues move across a bony area.
Bursitis is commonly caused by overuse and repeated movements. These can include daily activities such as using tools, gardening, cooking, cleaning, and typing at a keyboard. Long periods of pressure on an area. For example, carpet layers, roofers, or gardeners who work on their knees all day can develop bursitis over the kneecap. Aging, which can cause the bursa to break down over time. Sudden injury, such as a blow to the elbow. Bursitis can also be caused by other problems, such as arthritis or infection (septic bursitis).
Your heel may feel more sensitive to the cold and ache in cold and damp weather due to impaired circulation. These symptoms are often the result of failure to treat the injury properly from the outset and overicing.
Like all other forms of bursitis, initially the physician will take down the history of symptoms experienced by the patient, this will be followed by a detailed physical examination which involves checking for inflammation signs like pain, redness, and warmth of the heel area. The physician might examine further by moving the ankle a little to determine the exact location of pain. Further diagnostic tests including x-ray, bone scans, and MRI scan might be suggested if required.
Non Surgical Treatment
There are a variety of treatments for bursitis of the heel. Bursitis on the bottom of your heel (which is called infracalcaneal bursitis) is common in heels with thinning fat pads. Gel heel cushions or custom made orthotics (that have a horse-shoe cut and extra foam in the heel) can be lifesavers in reducing the pain. For bursitis of the posterior heel (retrocalcaneal bursitis), try to avoid going barefoot and to reduce the stress on the Achilles tendon by not over flexing your heel, the tighter your Achilles becomes, the more you compress the bursa sacs of the posterior heel. Heel lifts can help this, or wearing shoes with elevated heels (note that this method is not sanctioning high heels, as high heels can provide little comfort or support and usually are tight in the areas where your bursitis is most inflamed). Products such as AirHeel made by Aircast can help massage the bottom and back of the heel, helping to decrease pain.
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).
Contact your physician if bursitis pain is disabling (when movement of the joint is largely or entirely restricted), if the pain doesn?t subside after a week of self-care, or if the joint is red and swollen. Also call your doctor if you develop a fever, which could signal infectious bursitis-a condition that especially can afflict the elbow. Except for the fever, symptoms resemble other forms of bursitis, but infectious bursitis requires immediate medical attention.
