- The Achilles tendon is the largest in the body and connects the calf muscle to the heel bone of the foot. This condition involves the inflammation of this tendon which is often caused by repetitive stress on it through pushing the body beyond its abilities. An example would be trying to run a marathon when the body is only trained for a half-marathon. Symptoms include pain and stiffness along the tendon, thickening of the tendon, swelling and a bone spur is also possible.
Treatment includes stretching out the calf muscle and the tendon as well as strengthen the overall musculature of the foot to provide stability.
