Having a bunch of pain when I swing the golf club...used to be in the L4-L5 back area but now it is in my kidney region on my right side...especially when I follow thru...anyone experience this? I have dealt with the back issues for 2 years...to the point where I have worked on it so hard in the gym it doesn't bother me on the golf course or range as long as I warm up or workout before I play or practice...but this kidney deal hurts even if I walk...
