What are the symptoms of a peanut butter allergy???

Food allergy symptoms can range from a simple runny nose to shock.

Runny nose/ stuffy nose, rash, diarrhea, swelling, itchy mouth/ throat, shock, death Source(s): My son is peanut allergic.

Varies with each individual person. how you react to an allergy may be way different then someone else. We are all different so hard to say!
Symptoms may vary from simple itch,hives or rash , runny nose to shortness of breath/ breathlessness to shock ( decreased blood pressure,inability to breathe etc)
It can range everywhere from hard of breath to cardiac arrest. But non-life threatning allergy reastion include scratchy throat, upset stomach, weezing, coughing, lack of breath, etc. . . .
Your throat might swell up
before self-diagnosing.... check with your allergist who can determine through blood panels what foods you (or someone you love) are allergic to... peanut butter allergies can worsen over time and can eventually be life threatening.
