I m not sure what s happening. Any time I bend my left thumb down, it starts twitching. It literally barely started doing this five minutes ago. It s never happened before at all. It s just scaring me a little because I ve been told that when it does that, you have carpal tunnel apparently.
Hi there. First, don't worry, you do not have carpal tunnel syn Chat Doctor.  CTS mainly presents with dull aching pain over the wrist and hand, it's more in the night and certain group of people-commonly diabetics, pregnant ladies, chronic alcoholics, patients suffering from thyroid disorders are the ones who are more susceptible to have this condition. The person suffering from CTS gets multiple pins and needles like sensations over the palm. What you could be having may either be a sign of a muscle fatigue of your thumb flexor muscles, or you could be having a trigger thumb, which are again both really benign problems, and you need no worry about it.
