Hi, So few months ago my 2yr old started swelling up going really red and coming out in hives all over, He also kept squinting his eyes like they hurt, Brought him to chemist they taught he looked so bad they took photo's for doc, Brought him to doc he said its cold urticaria put him on steroids + antihistamine, He is on 3rd type of antihistamine now still not working, Everytime i bring him outside it happens even the moisture in air when running a bath sets it off! Any one else have this?
