Possible oral allergy???

Hi friends! I am someone that has not had any adverse reactions to food or chemicals until this past year.

Recently, I have started to experience severe burning and itching/ a heavy “bruising” sensation on the roof of my mouth when consuming certain fried foods (ex. Ruffles chips, Panda Express and other fast foods, etc.) and my wife tells me that a rash and “little black dots” appear in the affected area. I’m just curious if anyone else has had the same or similar experience, because I am having a hard time finding reputable and relevant sources online.
Thanks in advance :)
