Hello doctor,

I am not allergic to anything, but I have developed a phobia and have become allergic to nuts for the past two weeks. I am afraid to eat nuts, especially peanut butter. I have been eating peanut butter my entire life and all the nuts without any problems. However, now I have a fear of developing anaphylaxis from eating nuts. Can you please tell me if it is possible to develop a severe reaction to a food you have not been allergic to before? I have been eating nuts throughout my life, and now I am scared to eat them. Please help me overcome this.



Welcome to icliniq.com.

Did you have any allergic reaction after eating peanut butter or nuts ever? If the answer is no, this is a completely irrational fear, and I do not know from where you have picked such a thought. So do not worry and continue to eat peanut butter like before. However, if the answer is yes and there have been allergic symptoms, I suggest you get a skin patch test for food allergy.
