i'm not sure but i dont think using a mouse would do that but if its in your right arm i'd definitly go get checked out!
is using a mouse causing muscle knots and now numbness and tingling in my right arm specifically around bicep? . i work from home and am on the computer typically 7-8 hours. most recently i have been experiencing muscle knots in my upper shoulder and am now having numbness and tingling in my upper arm specifically in the area of my bicep. i work out regularly don't smoke and drink socially. i eat relatively healthy and was wondering if the use of the mouse is causing this?
