Hi all,

Various dr's have commented on 'atrophy of thenar eminence' on my right hand -....i think that this is the area near the thumb joint?. The padded area of my thumb did waste away a bit when i first had my symptoms a few years ago - and since the thumb area leading upto the wrist (if that makes sense!)has become bony looking and i can feel the 2 seperate ligaments where i suppose the muscle in between has wasted. (i never used to be able to!).

im confused as to whether this particular symptom is caused through vascular or nerve TOS?

i have read several links on here and on my own google searches which conflict.......
