Hive/Allergy/Stress relieve please?

For the past year or so, Ive been breaking out surrounded by these horrible hives that can and will cover my entire body with welts as big as dollar bills. They are hugely itchy and uncomfortable. The thing that I don't receive is that they can occur at random times such as swimming within the pool, sleeping, or when nothing special is going on. I know it's not a food allergy so I wanted to know this. Is it possible these reaction could be induced by stress?
Answers:
It is possible. You should get an allergy test though or at least possible go to a doctor.
