Hi. I've been playing bass for 5-6 months and when I practice the joints/knuckles in the middle of my left hand (primarily the middle three) hurts a lot or is sore. My doctor told me to take anti-inflammatories and it should stop but it doesn't, at all. If I practice a lot for a few days at a time my hand throbs, even when I'm not playing. I was wondering if this is normal? or if it could be stopped? Does anybody know of any excercises/stretches/warm ups I could do to help? I really like playing and I would really have to stop or something because of this . I'm a girl (I don't know if that makes a difference) and maybe I'm just grabbing on too hard to compensate for my relatively small hands, I don't know but the middle knuckle on my middle finger starts to hurt almost immediately when I start playing. Any advice would be really really greatly appreciated. Thanks!
