• Jobs, sports, or activities that involve repetitive motion

Symptoms

Problems may be swelling and pain, especially with motion.

Diagnosis

The doctor will ask about your symptoms and health history. A physical exam will be done. It will focus on the painful tendon. This is often enough to make the diagnosis. Imaging tests may be done to confirm it.

A blood test may also be done to look for signs of infection.

• Exercises to help with strength, flexibility, and range of motion

• Antibiotics to treat any infection

Prevention
