And Then...And Then...Along Came the Rest of the Story
>>>"DefinitionBy Mayo Clinic Staff
De Quervain's tenosynovitis (dih-kwer-VAINS ten-oh-sine-oh-VIE-tis) is a painful condition affecting the tendons on the thumb side of your wrist. If you have de Quervain's tenosynovitis, it will probably hurt every time you turn your wrist, grasp anything or make a fist. Chronic overuse of your wrist is commonly associated with de Quervain's tenosynovitis.
When you grip, grasp, clench, pinch or wring anything in your hand, you use two major tendons in your wrist and lower thumb. These tendons normally glide unhampered through the small tunnel that connects them to the base of the thumb. If you repeat a particular motion day after day, it may irritate the sheath around the two tendons, causing thickening that restricts the movement of the tendons."<<<
