Hi I Am 51 And Male, I Have Been An

Hi I am 51 and male, I have been an offset pressman and a drummer in rock bands (over 30 years doing both) I played a gig last night, after going to bed I was woken up to shoulder and arm pain. Both arms where completely asleep. I also feel less comfortable behind the drums, and it seems to be getting worse over the last year or so. Any exercises or diet advice. I do not live the best lifestyle but I am working to change that
