Causes And Risk Factors Of De Quervain's Tenosynovitis

De Quervain's tenosynovitis is a painful disorder that affects the tendons on the thumb side of an individual's wrist. The condition makes it painful to grasp objects, turn the wrist, or make a fist. It is most notably marked by pain and swelling near the proximal end of the thumb, but the longer the condition is left without treatment, the more the pain will spread. The pain can spread up the thumb, down the arm, or in both directions. It is a relatively common condition that can be treated with medications, physical therapy, and surgery if it has progressed too much to be controlled noninvasively.
