I am a 52 year old male. I work in construction. % years ago i was doing a renovation and my body became covered with red welts, extremely itchy. I saw several doctors none of whom made any sort of progress as to what it was. Here in 2016 about 2 weeks ago while doing another renovation I started getting the same spots again. They move around on my body from day to day. The doctor said im having an allergic reaction. The welts are increasing even though i have stopped this renovation. I am frustrated
