severe itching all over, redness of the skin. More like a rash than hives. Have taken hydroxyzine, Benadryl,Zyrtec and have been on Prednisone 3 times and nothing really seems to help. very temporarily. When I get in the shower, the minute water touches my shin I feel like someone lite me on fire. Have seen an allergist, Primary Doctor, No one can help me. I have had blood work that shows I m allergic to something but can t find what.
