What Causes Tingling And Swelling In Throat?

Hi..I was thinking I might have developed an allergy to somthing but i'm not sure what. I have an idea but wanted to get an opion. There have been two times now that i have felt like my throat is constricted or swelled, my tongue also swelled and tingled, and also had diarrhea. I was thinking Peanut allergy, but what do you think?
