Rash on lips

About 3 years ago, I had an allergic reaction to a food that I ate which caused my lips to swell up really bad. Fast forward to present day. I haven’t been able to use any kind of chapstick, lip gloss, balms etc. If I do, my lips swell up and hurt. So now that just stay looking chapped all the time. Sometimes they peel, feel sensitive for a day and then once the skin grows back, they peel again. I’ve seen multiple Drs for this, but no one knows what it is. I just got to the point where I didnt have the money to go see another derm. It’s more noticeable on my lower lip and just so annoying to constantly have chapped lips, but not be able to do anything about it.

I was just wondering if anyone was experiencing or has experienced the same and has found a remedy for it?
