Yes allergies can happen at any time and anywhere. I used to be able to eat strawberries and hazel nuts like there was no tomorrow and then all of a sudden in my 30's I developed hives when I ate those things. It's best to have him see an allergy specialist to find the root cause of his hives. Hives are no fun that's for sure!
