What Is Tendinitis?
Tendinitis is irritation and inflammation of a tendon, the strong tissue that connects muscle to bone. Repeated strain, sudden activity changes, or direct injury can affect a tendon near a joint. Tendinitis commonly produces localized pain, tenderness, stiffness, or pain during movement, especially when the involved tissue bears repeated load.

- Tendinitis affects a tendon near a joint.
- Pain often increases when the tendon bears load.
- Tendinitis is not the same as a muscle strain.
How Tendinitis Works

Tendinitis develops when a tendon becomes irritated after repeated loading, a sudden increase in activity, or a direct impact. The affected tissue may become painful when it contracts with its connected muscle or when pressure is placed near the joint. Symptoms often stay close to the involved tendon, although nearby movement can also feel restricted.

Assessment connects the pain pattern with the activity that triggers it. A clinician may examine tenderness, joint motion, muscle strength, and how the area responds to controlled movement. Tendinitis can affect the shoulder, elbow, wrist, knee, or ankle. Sports Injury Treatment may address the contributing movement pattern, while Corrective Exercise Therapy can support a gradual return to comfortable activity.

From the Advanced Injury Care Clinic team
When we assess tendinitis, we review the activity that brought on symptoms and examine the nearby joint and tendon. We also check movement, strength, tenderness, and whether the symptoms fit a tendon problem or suggest another injury. Our team uses those findings to guide care within Sports Injury Treatment.
Tendinitis in Practice: A Real-World Example
A recreational tennis player develops pain on the outside of the elbow after increasing practice sessions. The pain appears when gripping the racket and during other movements that load the involved tendon.
