Overview, Causes, & Risk Factors
There are two large muscles in the calf, the gastrocnemius and soleus. These muscles generate the power for pushing off with the foot or going up on the toes. The large Achilles tendon connects these muscles to the heel.
These are important muscles for walking. This tendon can become inflamed, most commonly as a result of overuse or arthritis, although inflammation can also be associated with trauma and infection.
Tendinitis due to overuse is most common in younger individuals and can occur in walkers, runners, or other athletes, especially in sports like basketball that involve jumping. Jumping places a large amount of stress on the Achilles tendon.
Tendinitis from arthritis is more common in the middle aged and elderly population. Arthritis often causes extra bony growths around joints, and if this occurs around the heel where the Achilles tendon attaches to the heel bone, the tendon can become inflamed and painful.
