For approximately 9 wks now I have been having an allergic reaction to something. I get welts all over my body which are extremelty itchy. My face, lips, eyes and tongue swells to where you can't recognize me. I occasionally have severe joint pain. I have been to the doctors and an "allergist". I have had alot of test which basically came back negative (R. Arthritis, Thyroid, Valley fever, Airborn allergies, Food Panel, etc) They said I have low allergies to trees and such and have a low allergy to eggs. They can't seem to find the problem. I am going crazy. I have been on the web just searching for the answer. Can it be the water, metals I don't know. I don't have alot of money and my ins is not the best. I have been on Zytec and Benadryl what seems like forever. They help control the problem but does not cure it. Can anyone help me?
