I think i have carpal tunel syndrome?

Sounds like you could have TOS, Thoracic outlet syndrome. It's caused by poor posture of the shoulders and often seen in people who spend a lot of time on the computer/mouse. Are you is the mouse on the left or right side for you? Check out this link to see if it sounds familiar. a href="http://orthoinfo.aaos.org/topic.cfm?topic=A00336" rel="nofollow"http://orthoinfo.aaos.org/topic.cfm?topi…/a Because you say there is pain and tingling in your upper arm, it makes me think it might be TOS and not carpal tunnel. Try really focusing on your posture and holding your shoulders back. If it seems to help, give it a few days of this and see where you're at. If it's still bad, you really need to see a doc to rule out any other nerve involvement or problems.
