Extending from the bottom of the calf muscle and the smaller soleus muscle on the back of the shin bone to the heel bone is the Achilles tendon. Achilles tendonitis, also known as tendinopathy, is a common sports injury and refers to the inflammation of the Achilles tendon.
The Achilles tendon is important for propelling the body forwards when walking or running. Aging and sports that heavily use the calf muscle can raise the risk of injury to this tendon. A sudden increase in intensity or frequency of an exercise can also contribute.
