How Would You Treat Bursitis Of The Foot?

Overview

A bursa is a closed, fluid-filled sac that functions as a cushion and gliding surface to reduce friction between tissues of the body. The major bursae are located adjacent to the tendons near the large joints, such as in the shoulders, elbows, hips, and knees. When the bursa becomes inflamed, the condition is known as bursitis. Bursitis is usually a temporary condition. It may restrain motion, but generally does not cause deformity.

Causes

For the most part, it is a genetic condition. You develop it by inheriting a foot type that is prone to the mechanical irritation that leads to the problem. If you have this particular foot type and wear shoes that rub and irritate the back of the heel bone (calcaneus) where the Achilles tendon attaches, then you are even more likely to develop this type of bursitis. The contributing factors include a supinated foot type, a heel bone with a prominence (or pointed shape that stick out toward the tendon) at the back, a tight Achilles tendon (referred to as Equinus by doctors), and a high arch. All of these factors simply make it more likely that the back of the heel will press against the shoe and rub. As the tendon gets rubbed the wrong way, the bursa starts to develop and fill with fluid. This response is really your body's way of protecting the tendon from damage, but it backfires. The friction from all that rubbing causes the bursa to become inflamed and swell. This causes the bump to become red, hot and stick out even further. Much like a sore thumb, it then gets irritated by even the softest shoes.

Symptoms

Nagging ache and swelling in or around a joint. Painful and restricted movement in the affected joint. Pain radiating into the neck or arms when bursitis strikes the shoulder (the most common site). Fever, when associated with an infection.

Diagnosis

Your GP or therapist will be able to diagnose you by both listening to your history and examining you. No X-rays or further investigation should be needed to confirm diagnosis but may be requested to check for any underlying health conditions that may have triggered the bursitis.

Non Surgical Treatment

The initial treatment for retrocalcaneal bursitis is to avoid activities that cause pain and take non-steroidal anti-inflammatory medications (for example, ibruprofen). Your doctor may recommend icing the heel several times a day and may prescribe physical therapy to improve flexibility and strength around the ankle. Physical therapy serves two functions, it can help the bursitis improve and it can help prevent future recurrences.

Prevention

Prevention can be accomplished by controlling your foot structure with good supportive shoes or arch supports. Pay attention to early signs of friction like blister formation. This tells you where the areas that are more likely to cause a bursa to form and subsequently a bursitis.
