i have had problems with hives for a few months now. they seem to have gotten worse the past couple of days to the point where i feel like my throat is getting bigger and it gets tender to the touch outside. tonight the hives are not responding to benadryl, hydrocortisone cream or an oatmeal bath. i am EXTREMELY uncomfortable. what should i do? my throat is getting tender on the outside. should i call my doc tonight or wait til the morning?
