What Causes Bursitis Of The Foot

Overview
Retrocalcaneal Bursitis. This bursa is located at the back of the heel. Bursitis in this area is often associated with conditions such as ankylosing spondylitis or rheumatoid arthritis. It can occur in healthy individuals who wear improperly fitted shoes. Symptoms include painful swelling that develops at the back of the heel. Calcaneal Bursitis. This bursa is located at the sole or bottom of the heel. Inflammation usually produces pain in the heel when standing. Causes include heel spurs, excess weight, injury, and wearing improperly fitted shoes.

Causes
The swelling is the result of the blockage of blood, tissue fluids and circulation in the heel because their normal movement has been disrupted by the force of the injury. Just like cars back up behind a traffic jam, causing congestion, exhaust and overheating, blood and fluids back up behind the injured heel, causing pain, inflammation, lumps and swelling.

Symptoms
Symptoms of Achilles bursitis are often mistaken for Achilles tendinitis because of the location of the pain at the back of the heel. When you suffer from Achilles bursitis you will experience some or all of the following symptoms which are most noticeable when you begin activity after resting. High heels can add pressure on the retrocalcaneal bursa, subcutaneous calcaneal bursa, and Achilles tendon.

Diagnosis
During the physical examination of a patient with calcaneal bursitis, the physician should keep the following considerations in mind. Swelling and redness of the posterior heel (the pump bump) may be clearly apparent. The inflamed area, which may be slightly warm to the touch, is generally tender to palpation. Careful examination can help the clinician to distinguish whether the inflammation is posterior to the Achilles tendon (within the subcutaneous calcaneal bursa) or anterior to the tendon (within the subtendinous calcaneal bursa). Differentiating Achilles tendinitis/tendinosis from bursitis may be impossible. At times, the 2 conditions co-exist. Isolated subtendinous calcaneal bursitis is characterized by tenderness that is best isolated by palpating just anterior to the medial and lateral edges of the distal Achilles tendon. Conversely, insertional Achilles tendinitis is notable for tenderness that is located slightly more distally, where the Achilles tendon inserts on the posterior calcaneus. A patient with plantar fasciitis has tenderness along the posterior aspect of the sole, but he/she should not have tenderness with palpation of the posterior heel or ankle. A patient with a complete avulsion or rupture of the Achilles tendon demonstrates a palpable defect in the tendon, weakness in plantarflexion, and a positive Thompson test on physical examination. During the Thompson test, the examiner squeezes the calf. The test is negative if this maneuver results in passive plantarflexion of the ankle, which would indicate that the Achilles tendon is at least partially intact.

Non Surgical Treatment
So what can you do to alleviate this type of pain in the foot? If the bursitis pain is occurring on the toes, bunion or back of the heel area the smart money would be on eliminating the shoes that seem to aggravate the condition. Eliminating these shoes may not in itself clear up the problem but you can be sure that if you continue to wear the offending shoes nothing you or your doctor do will permanently ?fix? the problem. A recurring theme that I use throughout this site that if you put an abnormally shaped foot in a dressy shoe it is literally the same as trying to put a square peg in a round hole, it will not fit. OK, so you threw away those dressy shoes and the foot still hurts, now what? Depending on the severity of the pain, over the counter anti-inflammatory medication may do the trick. The key here is to take the medication on an ongoing basis, according to the directions on the package to build up therapeutic blood levels. Assuming you can tolerate this type of medication, along with alternative treatments you can try). take the medication for 10-14 days. Stop if the symptoms have not dramatically improved. Icing the area during this period may also help reduce the symptoms.

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
After taking a history and performing a physical examination, your physician may order x-rays to rule out other disorders. Your doctor may administer injections of corticosteroids and a local anesthetic to reduce swelling and ease pain. Also, to reduce swelling, your physician may draw excess fluid from the bursa with a syringe and then tightly wrap and compress the joint with an elastic bandage. In severe, persistent cases surgery to remove the bursa may be necessary. For infectious bursitis, antibiotics will be prescribed.
