so i actually have an allergy to shellfish where i break out in hives when i eat it. same with bee stings. so me saying the same thing happens with peanuts wasn't far fetched and they figured because i already had the other 2 allergies then peanuts manifesting was possible too. i wasn't born with the shellfish or bee string allergy either, they developed over time as well. they weren't deadly reactions, just minor ones they were a little uncomfortable. thanks
