I have a problem with severe itching. No rash until I've scratched for days, it also becomes blotchy and puffy on my facial area. Sometimes it affects the torso area, this time it's the lower legs and lower arms and hands and face. The allergist cannot find anything I'm allergic to. I've tried several medicines, both oral and topical, but none seem to be doing the trick this time. Iget regular physicals and bloodwork etc. Thanks for you help, Diane
