for almost two weeks now I have experienced different places on my body first itching and then once I scratch at that spot it become inflamed, pink and warm to the touch. It goes from one place on my body to another. From the bottom of my feet, to my arms, to my legs, to my breast and then even this last weekend my right eye was swollen almost all the way shut....seems like my body may be reacting to something and nothing seems to help it....ice packs, warm compresses, cortisone, Benadryl....any thoughts on what might be causing this?
