I'm mid 40s. Tonight I finished off a few spoonfuls of my daughters peas. I never normally eat them but I was hungry. Instantly I had a huge sneezing fit for about 10 mins, streaming eyes, really tingling lips and tongue, difficult to breathe at a few points, my throat felt really tight. I'm not an allergic person, never had a reaction like this before. I don't normally even get hayfever. Can you suddenly become allergic to something
