Diki,

Sorry to hear about your pain/problems. Anytime I hear about someone experiencing pain in joints or muscles during playing, I always go back to the foundation and rudiments of technique and style.

I had developed sever wrist pain whist playing alot on keyboards. I was in so much pain, I started compensating.

I decided to go see a VERY GOOD teacher to evaluate my playing technique and BINGO! He discovered bad habits and poor ergonomic position of my hands, fingers and more importantly my wrists. We went through the basics (which I always thought I knew!) and reinforced them through exercise, repetition, and stretching and today I am pain free.

You might want to get back to basics and see if there are underlying bad habits that are contributing to your pain.

Al
