I have a problem when I work a long 12hrs shift and have been onmy feet for most of the time, my lower body starting with ankles and then my legs itch so crazy that I have almost made them bleed by scratching, no rash appears but I do makes streaks while raking my legs, only hot baths and body oil or lotions after help a little, then nothing can touch them for a couple of hours or it starts back up. What can I do? Is this a circulation thing or just skin stuff? Any help would be greatly appreciated.
