The Tendonitis occur when the tendon that connects the back of the leg to the heel becomes inflamed and hurts near the bottom of the foot. This tendon is called the Achilles tendon. It allows you to push with your foot down. You use the Achilles tendon when walking, running and jumping.
Tendonitis Achilles Causes
There are two large muscles in the calf. They generate the necessary force to push the foot or stand on the toes. The great Achilles tendon connects these muscles to the heel.
Achilles tendonitis may occur more likely if:
- There is a sudden increase in the amount or intensity of an activity.
- The calf muscles are very tight (not stretched).
- You run on hard surfaces, such as concrete.
- You run very often.
- You jump a lot (for example playing basketball).
- You DO NOT wear shoes that give your feet appropriate support.
- Your foot suddenly turns in or out.
Tendonitis due to arthritis is more common in middle-aged and older adults. Bone growth or spur may form on the back of the heel. That can irritate the Achilles tendon and cause pain and swelling. The flat foot puts more strain on the tendon.
