I know I've seen others post pictures about what they feel is atrophy and have been told no, but my left hand muscles really look smaller than my right especially in the thumb area. Does anyone think this could be atrophy or the beginning of atrophy? I have a lot of pain in my left hand in this area as well as twitching, numbness and tingling (which comes and goes) and it feels like my fingers on this hand do not work as well as my right when typing. I'm making quite a bit of mistakes lately. Mostly my middle finger, ring finger and pinky.
