DeQuervain's - Repetitive Strain Thumb Pain


Mouse use, keyboard activity, use of PDAs and cell-phone texting can all be causes of thumb pain. DeQuervain’s Tenosynovitis is an inflammation of the tendon or tendon sheath at the base of the thumb where it connects to the wrist. The tendons that pull the thumb away from the fingers (into the "hitch-hiking" position) become inflamed and irritated as they pass beneath the ligament that holds the tendons to the bone at the wrist.

My Product Choices as First Line of Defense Against Repetitive Strain Thumb Pain

This is a sample of the Comfort Cool Thumb Support available at Amazon.com. These are very comfortable supports that allow some mobility and function while limiting end-range thumb motion so that the tendons can rest, reducing inflammation.



These are very comfortable cold packs available from Amazon.com. My clients in the hand therapy clinic love these packs. The gel stays soft and pliable, providing good contact to bony areas. These are durable, comfortable packs that will not leak. The Velcro strap holds the pack in place allowing you to have some mobility while you perform your cold therapy. These packs can also be placed in the microwave for heat therapy.
