hi I went on vacation three weeks ago and out of no where had a reaction resulting in hives over at least 80% of my body I am 18 and only allergic to kiwi some types of deodorant when in direct contact and I did not know what to do so I took Benadryl and that works but it is only a temporary relief. I have broken out in what appears to be hives 5 times including break over the past three weeks it has not happened before I turned 18 and it is very uncomfortable the Benadryl works but makes me drowsy and interferes with my ability to stay awake during class is there any way to fix or test or prevent theses hives it seems to increase in severity every time it happens however I am not experiencing shortness of breath or any other function.
