I've Suffering Almost 2yrs.,with A Problem The Has Disrupted My

I've suffering almost 2yrs.,with a problem the has disrupted my life immensely,in every aspect of my being. I have what other Dr's. Consider a rash. My face mimics a typical lupus rash. My body burns,hurts,itches. I was told by 2 different Dr's. THAT I SEEM TO BE HYPERSENSITIVE TO GENERIC DRUGS. I DO HAVE EXTREME ALLERGY & other immune disoders... is it possible for a generic drugs to cause such havoc ?
