### output:

Hello, Welcome to Chat Doctor, The history and symptoms suggests me that you are having some food allergy, these allergens will stimulate the mast cell to release histamine which is producing all these symptoms. I would suggest you to undergo skin prick test (SPT) for different most prevalent food allergens to identify the food causing these symptoms. By doing to this it is possible to identify the allergen, by doing this you can avoid the food causing these symptoms, if it is not possible to avoid the food you can go for immunotherapy either with sublingual immunotherapy (SLIT) or subcutaneous immunotherapy (SUIT). Thank you.
