is it possible to have a minor peanut allergy?

i don’t wanna sound dumb or anything but can peanut butter allergies be minor? I’ve recently have had a weird obsession with peanut butter and crave everything peanut butter, it was never really my favourite flavour until one day i had a really good peanut butter treat and i’ve grown to obsess for it. i don’t know if that plays a roll or not but since getting this obsession everytime i eat it my mouth gets super itchy and and itch it with my tongue and it becomes swollen and closes some of my nostrils and throat. my lip also get super itchy and i itch them with my teeth making it hurt more when i lick my lips.. i’ve also had problems where a taste bud would burst or swell. it eventually goes away though and doesn’t swell enough to be alarming except for my nose.

so i’m just confused does this happen to everyone and i’m just aware about it or am i having a small allergic reaction or something else i have no idea
