What causes de Quervain's disease?

ANSWER

De Quervain's disease is a painful inflammation of tendons in the thumb that extend to the wrist. Doctors don’t know exactly what causes it. It can happen because of overuse, a direct blow to the thumb, repetitive grasping, and certain inflammatory conditions such as rheumatoid arthritis. Gardening, racquet sports, and some workplace tasks may make it worse.
