started getting hives and an increase in my asthma symptoms in sept 2010, no explanation for this that i am aware of, tried benadryl seemed to make it worse, lortadine didnt help either, the itching, burning, stinging was unbearable. started taking zyrtec, seemed to help a little but starts up again so i also started taking zantac along with the zyrtec. i am still getting some hives and itching but now for about the past 3-4 wks now i'm also getting nausea, please help!
