If you are experiencing pain only in your thumb, you might be suffering from any of the following conditions:
- CMC Thumb Arthritis: You might be having CMC thumb arthritis if it pains at the base of your thumb (the point where the thumb meets the wrist). In the case of CMC thumb arthritis, you may also feel pain while pinching and/or gripping, particularly when you hold tiny objects.
- de Quervain’s Tenosynovitis: You might have this condition if it pains along the sides of your thumb while moving it into your hitchhiker position. If you have this condition, you might also feel pain while bending the hand towards the little finger. In addition, the pain will shoot up in the forearm along the side of the thumb.
- Gamekeeper’s or Skier’s Thumb: You might have this if it hurts for you in the middle joint of the thumb at the point where it joins to the hand. Moreover, you will also have difficulty gripping and holding objects. Furthermore, you may find it painful and hard to pinch.
- Trigger Thumb: You might be having a trigger thumb if there is “popping” pain while bending and/or straightening the tip of the thumb. In this case, the thumb will stick in a bent position, and you need to pull it to become straight.
