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.

Other causes of de Quervain's tenosynovitis include:

  • Direct injury to your wrist or tendon; scar tissue can restrict movement of the tendons
  • Inflammatory arthritis, such as rheumatoid arthritis
