To avoid burns until the body's overacid condition is remedied one can place 
the unit on the palm of the hand or the sole of the foot.  These areas don't 
burn as the skin is thicker here.  If you cut off about the top six or eight 
inches of a crew sock it will make a good elastic holder for the hand, foot, 
leg etc.  Might want to reread the instructions on Croft's site.   pj
