yes. common contact reaction.
has happened many times to my son.
biggest reaction was total body hives after being hugged by father who had eaten peanuts outside home, washed hands, but traces of peanuts on clothes. Son was about 4 at the time. very painful reaction.
also can happen with enviromental allergies, such as hives when jumping on bed, or crawling under bed from dustmite.
or running under trees , naked at 2, in garden during tree pollen season.
or when 1 sitting car, and vents pointed in direction to blow on one side of body, causing hives on one side, from hay fever reaction in summer.
last year, at 15yrs, watching fireworks, swollen lips, cause, mold.
treatment,
wash skin and give antihistamine. as per doctors advice. esp with regard to full body hives and peanut reaction!
