Whilst practicing minor scales I started to get a mild cramp in my left palm. I didn't pay a lot of attention to it, because It does happen from time to time when i'm working on scales for quite a while.. So finishing up my practice (a few minutes after the mild cramp) I noticed that the muscle in my hand, just under my pinky is quite large.. After some research I'm pretty sure it's the hypo thenar eminance muscle group. It's definitely larger than my right and it's almost warm. Has anyone had this happen to them on here, and if so what did you do? Is it a common muscle cramp and should I just drink water and make sure and take potassium and stretch it, or should I consider it to be something worse?
