Bursitis Of The Foot

Overview
A properly functioning heel is essential to normal, smooth, and painless gait. The heel is the first area to strike the ground during normal gait, which means it takes the brunt of the stress incurred during walking and running activities. Of course, this also means that the heel is highly prone to injury. One such injury is called heel bursitis.

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
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
Caregivers may give you special shoe inserts with a cutout around the tender area. You may also be told to wear shoes with a reinforced heel counter. This will give better heel control. You may need other shoe inserts (wedges) to raise your heel so it does not press against the back of the shoe. You may also wear shoes that are open in the back, such as sandals that have no strap across the heel. You may use ibuprofen (eye-bu-PROH-fen) and acetaminophen (a-seet-a-MIN-oh-fen) medicine for your pain. These may be bought over-the-counter at drug or grocery stores. Do not take ibuprofen if you are allergic to aspirin. You may be given shots of medicine called steroids (STER-oids) to decrease inflammation. Caregivers may add local anesthesia (an-es-THEE-zah) to the steroids. This medicine helps decrease bursitis pain. Because these shots decrease swelling and pain, you may feel like your ankle is healed and that you can return to heavy exercise. It is important to not exercise until your caregiver says it is OK. You could make the bursitis worse if you exercise too soon. You may need surgery to remove the bursa or part of your ankle bone. Surgery is usually not necessary unless the bursitis is very bad and does not heal with other treatments. Your caregiver may want you to go to physical (FIZ-i-kal) therapy (THER-ah-pee). Physical therapists may use ultrasound to increase blood flow to the injured area. Caregivers may use massage to stretch the tissue and bring heat to the injury to increase blood flow. These and other treatments may help the bursitis heal faster. Exercises to stretch your Achilles tendon and make it stronger will be started after the bursitis has healed. You may gradually increase the amount of weight you put on your foot when caregivers say it is OK. You may be told to stop exercising if you feel any pain.

Prevention
You can help to prevent heel pain and bursitis by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch of the foot and cushion the heel. If you are prone to plantar fasciitis, exercises that stretch the Achilles tendon (heel cord) and plantar fascia may help to prevent the area from being injured again. You also can massage the soles of your feet with ice after stressful athletic activities. Sometimes, the only interventions needed are a brief period of rest and new walking or running shoes.
