My uncle has had it badly all his life- he gets it on his elbows and knees... He now takes 'Transfer Factor'', by 'For Life', and it has almost cleared it up. Im not selling the stuff btw- Im just amazed how well it worked. Takes time, and its not something you rub on- but imagine not having to?!! Just a thought anyways. PM me if you want me to find out from him some details...
