It all started out of the blue. I'll get them on my neck, lower back, forearms and legs. Whats really strange is that if I touch or rub an area on my face it gets hot and red, no bumps appear and it doesnt get itchy just red and hot, sometimes it swells but it throbs like crazy. I also noticed that if i grip something too hard my hands start to hurt. I was carrying bags on my arms and when I removed them there were red welts. I have not been to the doctor yet. I have been taking Claratin and that seems to help. I have changed everything I can think of. Laundry soap, body wash, hair product, deodorant everything.
