-- Posted by Ollie92 at 4:15 pm on Dec. 2, 2008 I was playing guitar this afternoon so i'm not sure if there is any relationship or not... My arm (right) that i write/strum with has gone kinda stiff and there are like pinching pains , like muscle spasm where the muscle tightens and releases and feels really weak for like a split second. could i have just pulled a muscle while playing (which would be lame but i'll take it)  ... any help ? -- Posted by Riot at 4:15 pm on Dec. 2, 2008 Just rest it for now. -- Posted by Rebecca li at 4:15 pm on Dec. 2, 2008 Go to a doctor? -- Posted by roryboy at 4:17 pm on Dec. 2, 2008 Guitarthritis, my brother gets it still. Lay off for a bit and take it easy for a while should clear up. -- Posted by LoveThyBass at 4:17 pm on Dec. 2, 2008 i play guitar myself, i get that randomly, jsut rest it untill it starts to feel better, i got it so bad once that it started on my wrist and within 3 day slowly moved to my shoulder, killing pain the whole way, just wait it out, you dont wanan risk carpel tunnel (sp?) -- Posted by 0h h3ll n0 at 4:17 pm on Dec. 2, 2008 Haha I've had that exact same pain when I played GH3 too much. I think it is probably muscle strain from playing your guitar. You should just rest, don't play for a few days or you'll make it worse.
