I have absolutely no pain in areas affected,warm feels good sometimes ice feels good,but neither of them causes me pain..I just have more and more of the left side of my body going numb.I have been using an interferential unit to run some low voltage through my leg--seems to be giving me tingles in areas that were completely numb..going to keep it up..will see a neurologist on the 9th,anxious to hear his assessment thank you
