I used to get hives and severe itching when I am irritated with a situation. This went on for about 15 years. It usually occured on my legs, neck or chest. I have had many skin issues over the years, tried most otc and prescription stuff. After I quit drinking/ingesting products containing Aspartame or other artificial sweetner MOST of my skin conditions disappeared. Even a rash I had for years above my knees was gone within a week. Then I removed all paraben containing products from my regime. Even better. Then I removed all soy containing food items (almost all processed foods here contain soy), even better. I had allergy panels done and I am not allergic to soy, but I am allergic to cats, many trees, and shrimp. There's not a lot I can do w/ the allergy information since those things were not causing my symptoms. Good luck!
