I am a 23 year old mail.
Two days ago I started getting a very itchy scalp and armpits. I awoke later that night with hives all over my torso, they were very itchy. I took an Antihistamine whcih helped a great deal. The next day the hives cam back, much less in strength an itchyness. Today I awoke with two hives on on each wrist, and some more under my armpits. I can not think on anyting that I would be allergic to, ate ot otherwise. The only thing I can trace back to a possible cause is an old piece of fiberglass insualtion when cleaning out a storage area. I can handel the itching but I am mildy worried when these hives will go away. I have never had any breakouts of any nature, I can not even recall ever having Hives. It seems to be getting better, but I am concerned with some infection like mites or other parasitic insctes. Thank you.
Hives generally do just what you describe--come out of nowhere, go up and down with no pattern at all, then go away on their own, as mysteriously as they came. Despite their "allergic" reputation, hives almost never represent true allergy to one thing, like a chemical, food, or parasite. I wouldn't worry if I were you. Just take antihistamines as needed and watch the hives disappear over a few days or weeks. If they don't go away in 2 weeks, I suggest you see a doctor.
I had a tetnus shot and 2 weeks later broke out with hives. It was hard to make the connection. Is it possible you had a tetnus shot or some other shot with in a couple weeks or some other medication? Try taking a bath in Alveeno and also Alveeno lotion.
