A bursa is a fluid-containing sac that is present at many areas of pressure on the body. Its job is to protect these areas of pressure by being a shock absorber. A bursitis is an abnormal inflammation of the bursa sac caused by abnormal excessive pressure, stress and/ or strain over the area it is protecting. On the heel bone, there are two bursa sacs: one on the bottom and the other on the back. Specifically on the bottom of the heel, it is known as an Inferior (bottom) Calcaneal (heel) Bursa. On the back of the heel, it is called the Retro (back) Calcaneal Bursa. When either of these bursas become abnormally stressed, strained, or swollen, the result is bursitis of the heel. It is this bursitis that is the reason for pain in the heel upon arising (Poststatic Dyskinesia) in the morning or after resting for a while. You can either develop these bursitises with or without the presence of heel spur (explanation to follow). As stated before, Morton?s Toe can cause this by causing over pronation in the foot.
Certain medical conditions and medications suppress people’s immune systems and make them more susceptible to septic bursitis. For example, people with cancer, HIV/AIDS, lupus, alcoholism, chronic obstructive pulmonary disease (COPD), and diabetes may be more likely to get septic bursitis. History of inflammation of the bursa. Patients who have had bursitis in the past have an increased chance of getting it again. There may be more than one reason why the retrocalcaneal bursa is inflamed. In these cases, treatment should address all of the causes.
What are the symptoms of heel bursitis? pain, swelling, tenderness, redness, and/or warmth at either the bottom of the heel or top of the heel, depending on the degree of swelling, pain may be a dull ache or substantial enough to cause limping, running, jumping, and walking activities may exacerbate pain, wearing poorly fitting, tight, or high-heeled shoes may exacerbate pain.
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
With posterior Achilles tendon bursitis, treatment is aimed at reducing the inflammation and adjusting the foot’s position in the shoe to relieve pressure and motion on the back of the heel. Foam rubber or felt heel pads can be placed in the shoe to eliminate pressure by elevating the heel. Placing protective gel padding over the painful bursa or stretching the back part of the shoe and placing padding around the inflamed bursa may help. Sometimes a special shoe, such as a running shoe designed to stabilize the midsole heel, devices placed in the shoe (orthoses), or both can help to control abnormal foot and heel motion contributing to the posterior heel irritation. Other shoes have padding that reduces irritation to the posterior heel and Achilles tendon.
Surgery is rarely done strictly for treatment of a bursitis. If any underlying cause is the reason, this may be addressed surgically. During surgery for other conditions, a bursa may be seen and removed surgically.
