[quote name='larrikin' post='337078' date='Nov 26 2008, 11:16 AM']What's going on, the muscle underneathe my thumb (don't know what it's called), hurts whilst i'm playing my bass, like a burning feeling that really affects my playing - has anyone else had this???[/quote]
I get this I have always put it down to cramp, I would like to know if there is anything that can make it stop.
