My PF is in my left foot. The Korean guy put one needle in my left wrist, and then five or six at strategic places around my left foot - including right into the most painful spots on the heel.
The Chines guy put two needles in my right hand, then st strategic points on my lower left leg, and a couple into the foot. He also "cupped" several points on the left leg.
I have also been on heavy doses of Vitamin C, and have just started glucosomine sulfate.
