Hello I have had an allergic reaction in the last few days but thought it had blown over . Then it blew up as I must of had something that effected me. I am allergic to corn and milk. I had partly closure of my throat and wheezing. I had flu like symtptoms and now 3 days still have running nose and wheezing has eased. I take allergy pills if I feel any signs of an attack coming on. Long term the effects on the reactions what are they also when I sometimes get an attack I get blocked ears and ulcers in my mouth.
