Not sure, you may have heard about
this already. But I have a friend who gets hives all over her body more so when she goes through periods of being very nervous. Her's are what they call "shingles".
I myself have gotten hives on my body due to a medication I was taken, found out it made my skin sesitive to the sun, which is why it broke out, so they changed it. Then it was fine, though it did something to me because my first expoosure to the hot sun each summer causes the areas exposed to break out, mostly my hands and arms.
Hope your doctor diagnoses you to give you peace of mind
