The Achilles tendon is the thickened cord or fibrous band that runs down the back of one’s leg and attaches to the heel bone. A prime function of this muscle or tendonous structure is to assist in moving the foot up and down. Athletes at all competitive levels, frequently encounter problems with this tendon. It is subject to injury from a direct impact, can suffer from over use or excessive training, or can just start hurting as a result of shoe pressure. The patient with an Achilles tendonitis will most often have pain and swelling in the lower portion of the tendon just above the heel, will have discomfort when moving the foot upwards thus stretching the tendon, and will probably note that the condition has worsened over time. These patients can have significant discomfort and will frequently take themselves out of physical activities prior to visiting the physician.
