This is a very common condition that leads to foot pain . Once you understand what it actually is you will wonder why it does not occur more often, particularly in the foot. It is an inflamed bursal sac. A bursal sac is a sac filled with fluid that acts to lubricate and reduce the friction between two surfaces in the body, usually muscles and tendons as they glide over bony prominences, however their purpose in not limited to just muscles and tendons. The body contains literally hundreds of bursal sacs but in the foot there is just one naturally occurring (adventitious) bursal sac. It is located between the Achilles tendon and the heel bone (calcaneaus), otherwise known as an achilles tendon bursal sac.In this instance the Achilles tendon is protected from the pressure of the heel bone pressing against it when we walk.
Bursitis is caused by overuse or excessive pressure on the joint, injury, infection, or an underlying condition, such as osteoarthritis, rheumatoid arthritis, gout, pseudogout, or ankylosing spondylitis. When bursitis is caused by an underlying condition, the condition must be treated along with the bursitis. When bursitis is caused by infection, called septic bursitis, medical treatment and antibiotics are necessary.
Pain when activating the Achilles tendon (running and jumping) and when applying pressure at the point of attachment of the tendon on the heel bone. Contrary to the tenderness occurring with inflammation of the Achilles tendon, the tenderness is localised to the point of attachment to the heel bone.
Diagnosis of heel bursitis can be made by your health practitioner and is based on the following. Assessing the location of the pain by palpating the back of the heel. Assessment of any inflammation at the back of the heel. Assessment of biomechanics and foot function. Ultrasound or MRI can reveal inflammation of the retro calcaneal bursa.
Non Surgical Treatment
Non-operative treatment is the standard approach to treating posterior heel pain. It is highly desirable to treat this condition non-operatively, as operative treatment is often associated with a prolonged recovery. Traditional non-operative treatment includes the following. Heel Lift or the Use of a Shoe with a Moderate Heel. Walking barefoot or in a flat-soled shoe increases the tension on the insertion of the Achilles tendon. Using a heel lift or a shoe with a moderate heel can help reduce the stress on the tendon and decrease the irritation caused by this condition.
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.
