Itchy rash on lips

[melabelle]

I've gotten a rash on my lips 3 times in the last 6 months, even though I've never had any problems with skin allergies before. The first two times I assumed it was poison ivy, transferred from my outdoor cats to my hands to my mouth. It's very similar to that type of rash - small, dryish bumps that tingle and itch quite a bit. They're barely visible on my lips and redness isn't evident because of their location. There's a little dryness, itching, and slight redness to the sides of my mouth as well, but no bumps. The rash is only on my mouth this time, while the other two times I had a few bumps on my arms as well. I haven't come in any contact with outdoor cats or poison ivy/oak in ANY capacity this time, so it can't be that. Could it be some sort of cat dander/saliva/urine allergy that only manifests occasionally? I just got a new kitten, but I spent most of the past 6 months living in a house with 4 or more cats and only had the rash twice (about a week each time). I've also had cats for 10 years and never had any allergy issues before. Anyone have any ideas?

Hey there! Did you by any chance eat nuts any of those times? I've suddenly developed this allergy to nuts, and those are exactly the same symptoms!

I have the same rash on my lips. I get it when I eat mango.
