Question:

"Scallywag asked "First off I want to thank you guys and gals at Jam-play for the wonderful opportunity you give everyone to learn to play so many different styles, but most importantly we can communicate with you directly and get answers to those nagging questions.... My question pertains to PAIN! No, I’m not talking about fingertip pain, that’s expected. What I’m talking about is pain on my right hand about 1 inch directly below my pinky over the crease of the palm. (I’m left handed so the pain is on my right hand….) Is the problem due to tendons or muscles or both and what is the best way to recover? Note: I’m a newbie and practiced the chromatic cords for 2-1/2 hours in a single session.""
