What is Trigger Thumb?
As you’ve just heard in the video, trigger thumb is a common and debilitating condition. The tendons in your thumb and fingers are covered in a tunnel like structure of tissues that are called sheaths. If you have trigger thumb, your tendons have become inflamed. Because of this inflammation or swelling, your tendons are no longer properly gliding through your sheaths. When this happens, the base of your fingers may lock up, click, or pop. Essentially, your fingers get stuck in a non relaxed position. This has the potential to be a very painful and frustrating condition, as you lose the full function of your thumbs. This condition can happen to all of your fingers including your thumbs, index, middle, ring, and pinky.
