Lips look like I've lipstick on?

[PromisingYoungWoman]

Noticed a bit of a tingling in my lip/skim above my lip last night. Woke up to red lips today which are slightly tingly, swollen and red. Haven't eaten anything new or used any new products on my face nor do I have a history of coldsores or have been recently exposed. Picture attached but slightly worried in case it's some kind of autoimmune issue.

Any new medication?

@Notaboutthebass no new medications either

Are you feeling well?

@Notaboutthebass yes I feel well in myself. No temp or any other symptoms. No rash elsewhere. Just a bit worried that it may be a sign of something more serious. My lips aren't sore, just feel tight. The tingling has mostly stopped. But still discoloured

This is what happens to me when I eat pineapple

@CharlotteDoyle oh that's interesting. Mines started shortly after eating last night (a meal that I eat often). Weirdly it's happened again this afternoon after eating a completely unrelated food.
