it is indeed a form or CTS
if you run to a doctor like most people do all he will do is put you on some drugs which you will need to take FOR LIFE
my solution is you need to take a break from what is making it worse.. not sure what your work is but maybe ask your boss to work in the office instead for a month. also this would be a good time to find a good acupuncturist who can help with this. 90% of them are a complete joke, 5% are okay, and 5% are excellent. you have to find the best one in your town, read reviews
