De Quervain’s tenosynovitis

De Quervain’s tenosynovitis occurs when the tendons around the base of the thumb are irritated or constricted. The tendons become inflamed causing pain and tenderness along the thumb side of the wrist. The inflammation may be due to overuse, pregnancy and rheumatoid arthritis. A “catching” or “snapping” feeling may be felt when moving the thumb. The pain is more noticeable when forming a fist, grasping or gripping things, or when turning the wrist.

The goal in treating De Quervain’s is to relieve the pain caused by the irritation and swelling. Wearing a splint, cold therapy and avoiding activities that cause the pain and swelling may allow the symptoms to go away on their own. Adjusting the wrist and adjacent joints may help decrease constriction. If the condition goes too long without treatment, the pain may spread farther into the thumb and forearm.
