Rhinitis Treatment Care

Antihistamines are use to treat_______.
a) hay fever
b) rashes
c) insect bites
d) all of the above.

I’ve always had quite an allergy problem. But, 3 days ago, My stomach started itching. I thought nothing of it, just that my pants were on to tight. Well, shortly after that my symptoms turned in more hayfever like. I had so much post nasal drip that I took off running up the stairs because it was causing me to gag. After throwing up from all the excess mucus. I took a look in the light, and saw hives all over my stomach. I went to the Pharmacy and picked up some benadryl. It helped stop the postal nasal drip.. but the hives still continue. If I dont take the benadryl atleast 2 or 3 times a day, the post nasal drip/hay fever symptoms start up again. Do people who are prone to hives typically exhibit hayfever symptoms with them? Or is it possible that hives is now going to be a new reaction that I have when I encounter my triggers.. “dust, mold.. ect”
Any help is appricated.
