Playing Guitar Creates Foot Injury ?

Oh, the pain is a pain in the a**! I play standing and I have to consciously not rock back and forth while playing. It is hard not to move with the music. I'm older than the average bear and my feet get really sore. My wife wonders why I don't want to go for a walk. Anyway, pain is going to live in our feet the longer we play...me? 74! I can't stop playing.

Good luck and have fun.
