For some time now I've started to get pain when ever I play finger style. The pain is coming from my thumb on the plucking hand. To really be specific the pain is about a half inch below the first joint of the thumb, palm side and kind of goes around to the side a little bit. I'm starting to get concerned, I'm getting worried that I all ready screwed my hand up some how. Any body have anything like this before? Or know anybody who has had this?
