Hello, I have a 9 year old son who has been having severe hives outbreaks almost daily for the last 4 months, even on antihistimines. We have been to an allergist who looked at him and said he does not have allergies. Did not do any testing. we have been to the er 4 times in one month...one time with facial and throat swelling. he is taking prescription antihistimiines now. has been on 4 rounds of steroids, and continues to break out. nothing has changed in his environment. other symptoms that he displays are tingling mouth, feet and hands are numb/tingling, low grade fever off and on for the last 4 months. extremely fatigued (which is probably due to the antihistimines.) he went about 1 week without breakout on the prescription antihistimines. i cant shake to mommy instinct that this is just hives.
