Tendons are the strong, cord-like bands of connective tissue that link muscles to bone. If a tendon is made to work too hard, for too long or in the wrong way, damage and tiny tears develop in the tendon. This is accompanied by inflammation which is the tell-tale sign of the condition.
The body’s normal response to an injury is to send extra red blood cells carrying the oxygen and nutrients required for healing and white cells to fight off possible infection. Waste products such as inflammatory chemicals are then carried away. All of this helps speed up healing but should only last for a few days. If an area is repeatedly irritated, the process keeps going resulting in the continued inflammation described as tendonitis.
There are four main causes of foot and ankle tendonitis:
