Tendonitis is a condition that describes the inflammation of the tendon.
Tendons are collagen-fiber tissues that connect the bones and muscles, which allow the body to move. There are thousands of tendons in the body. They allow each joint of the body to bend, flex, or rotate during movement.
As the tendon becomes inflamed, it swells and causes pain and stiffness during movement. Usually, people feel tendonitis pain near the joint. It’s often confused with arthritis.
Tennis elbow, trigger finger, De Quervain’s syndrome, and runner’s knee are common conditions affecting the tendons. Of course, tendonitis can also affect the shoulders, ankles, and toes.
