Bursitis Foot Pad

Overview
Infracalcaneal bursitis can significantly affect your quality of life and your ability to perform your activities of daily living, due to pain and impaired gait. Inflammation of the bursal sac under your heel bone occurs because the bursa is abnormally stressed or strained in some way or bears excessive pressure for prolonged periods. Constant pressure and friction from footwear is a common cause of this health problem, and any treatment plan addressing infracalcaneal bursitis should include recommendations for footwear to avoid or use. Infracalcaneal bursitis may be diagnosed in several ways, including palpation, or light pressure applied to your affected area. If your heel pain has existed for an extended period, X-ray imaging studies may reveal localized calcification in your infracalcaneal bursa, though this is not always the case. MRI images are sometimes used as a diagnostic tool for this health problem, though MRI studies are considered unnecessary for diagnosis in many cases.

Causes
The calcaneal bursa can become inflamed in patients with heel spurs or in patients with poor-fitting shoes (eg, high heels). Inflammation can occur secondarily from Achilles tendinitis, especially in young athletes. Patients exhibit tenderness to palpation of the bursa anterior to the Achilles tendon on both the medial and lateral aspects. They have pain with movement, which is worsened with dorsiflexion.

Symptoms
When the bursa becomes inflamed after an injury, symptoms usually develop suddenly. When the bursa develops without an injury, symptoms may develop gradually. With both posterior and anterior Achilles tendon bursitis, symptoms usually include swelling and warmth at the back of the heel. A minimally red, swollen, tender spot develops on the back of the heel. When the inflamed bursa enlarges, it appears as a red lump under the skin of the heel and causes pain at and above the heel. If posterior Achilles tendon bursitis becomes chronic, the swelling may become hard, fluid-filled, and red or flesh-colored.

Diagnosis
Carrying out a diagnosis for bursitis is fairly straightforward. The doctor will examine the affected area and ask the patient some questions about his/her recent activities. If the patient has a high temperature the physician may take a small sample of fluid from a bursa near the affected body part. The sample will be tested for bacteria, and perhaps also crystals. If the patient does not get better after treatment the doctor may carry out further tests so that he/she can eliminate the possibility that the symptoms might not be due to something else. These may include an x-ray, to make sure no bones are broken or fractured. Blood tests, to check for rheumatoid arthritis. A CT scan or MRI scan to see if there is a torn tendon.

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.

Surgical Treatment
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).

Prevention
Maintain proper form when exercising, as well as good flexibility and strength around the ankle to help prevent this condition. Proper stretching of the Achilles tendon helps prevent injury.
