Should i ever be afriad of possibly developing food allergies?

You can develop an allergy but a severe one usually doesn't just appear. Drug allergies and food allergies are different. Anaphylaxis is a big deal because your throat could swell. The anithistamine stops it. I have personally been through anaphylaxis twice. I would recommend seeing an allergist. You can get an epipen and you won't need to worry.

I have a food allergy and my symptoms are usually nausea, hives on my face and arms, dizziness, feeling like I'm going to pass out, warmth, redness, sneezing, and difficulty breathing. I've only ever had mild reactions, until last night when I went to the ER and they had to give me epinephrine for the symptoms listed above. You can NEVER tell if your next reaction is going to be severe or not. You should see an allergist! You should also be aware that swelling and difficulty breathing are NOT the only symptoms of anaphylaxis. Other symptoms can include nausea, vomiting, diarrhea, low blood pressure, dizziness, pale/blue colour, redness, weak and rapid pulse, and unconsciousness. Anaphylaxis is not very rare, it's unpredictable. By the way, most people outgrow their milk allergy by age 5, so you shouldn't worry too much about that. I'm allergic to peanuts (which are NOT the same thing as tree nuts). The other major allergens in Canada are wheat, soy, sesame, mustard, fish, shellfish, crustacean, and egg. It might sound crazy, but it's really likely that your mind is telling you that you are allergic to all these foods, when you really aren't. It's probably just anxiety, but I would get allergy tested just in case.
