I got a food allergy and I was wondering what I can do to get rid of them like. Home remedies or other treatments like creams?

Food allergies. Food allergy is a sticky subject, with different doctors having different tests, giving you different opinions. There is no perfect test. But no, there are no creams or home remedies that I am aware of. The treatment is avoidance of the offending food, with injectable Epinephrine if you have a history of anaphylaxis after eating a particular food.
