Have to keep an epi-pen for bee/wasp stings. Have a lot of antibiotic allergies too.
I have a mild allergy to raw bananas. Like you and mangos, my lips and mouth tingle and itch. Then I get a stomach ache. Cooked bananas are fine (don't know why). My banana allergy is not epi-pen level. I can stop the tingling and itch of the mouth with a glass of milk. The stomach ache passes within 20-ish minutes.
