For as long as i can remember whenever i play sitting down my right shoulder (picking hand) starts to ache. I don't even have to be playing for long for it to start to kick in. I'm pretty new and i've red somewhere that you can't bend your wrist over the guitar so i don't do that, my elbow goes straight up and is perpendicular to my wrist.
Am i doing something wrong?
Also i have just tried to ignore and play through it but it gets to a point where it hurts way to much. The pains go away a couple minutes after i put my arm down thou.
Any suggestions?
