Bursitis Feet PadsOverview
Bursitis occurs when a bursa is irritated from frequent pressure and it becomes inflamed. Due to the location close the Achilles tendon, Achilles bursitis is often mistaken for tendinitis. Achilles bursitis is a common overuse injury in runners, ice skaters and other athletes.
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 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.
Your doctor will take a history to find out if you have the symptoms of retrocalcaneal bursitis. By examining your ankle, he or she can generally tell the location of the pain. The physician will look for tenderness and redness in the back of the heel. The pain may be worse when the doctor bends the ankle upward (dorsiflex), as this may tighten the achilles tendon over the inflamed bursa. Alternatively, the pain may be worse with toe rise, as this puts stress on the attachment of the achilles tendon to the heel bone. Imaging studies such as X-ray and MRI are not usually necessary at first. If initial treatment fails to improve the symptoms, these studies may be obtained. MRI may show inflammation.
Non Surgical Treatment
Podiatric Care may include using anti-inflammatory oral medications or an injection of medication and local anesthetic to reduce the swelling in the bursa. An injection may be used for both diagnosis and for treatment. When you go to your doctor, x-rays are usually required to evaluate the structure of your foot and ankle to ensure no other problems exist in this area. They may advise you on different shoewear or prescribe a custom made orthotic to try and control the foot structure especially if you have excessive pronation. Sometimes patients are sent to Physical Therapy for treatment as well. To aid in relief of pressure points, some simple padding techniques can be utilized. Most all patients respond to these conservative measures once the area of irritation is removed.
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.
