What Is Tendonitis?

Tendonitis is irritation or inflammation of a tendon, the strong band of tissue that connects muscle to bone. It often develops when repeated activity places more stress on a tendon than the body can comfortably handle. The condition may cause localized pain, tenderness, stiffness, or discomfort during movement near the affected joint.

Key Takeaways About Tendonitis

  • Tendonitis affects connective tissue between muscle and bone.
  • Repeated loading may increase tendon irritation.
  • Tendonitis is not the same as a muscle strain.

How Tendonitis Works

Tendonitis describes a tendon response to repeated stress, force, or friction. A tendon transfers force from a muscle to a bone, so irritation can affect how a nearby joint moves. Symptoms often appear near the involved tendon and may change with activity or rest.

Evaluation considers the location of discomfort, the activity that increases symptoms, and the joint's movement. A clinician may compare strength, flexibility, and tenderness on both sides of the body. Range Of Motion findings can help show how tendon symptoms affect movement, while a muscle strain involves injured muscle fibers. Sports injury treatment may address movement patterns and surrounding tissue stress as part of care.

From the Arrowhead Clinic Chiropractor Marietta team

When we assess tendonitis during Sports Injury Treatment, we ask how the symptoms began and which movements increase them. We also check nearby joint motion, muscle balance, and tenderness. That practical information helps us distinguish tendon symptoms from related problems, such as a muscle strain or joint stiffness.

Tendonitis in Practice: A Real-World Example

A recreational tennis player develops pain near the outside of the elbow after repeated backhand practice. During Sports Injury Treatment, the evaluation considers the tendon area, grip and swing mechanics, and nearby joint movement.
