Help with Lips

I started a weird lip thing in my last year of high school and it hasn't gone away in years. Whenever I use any products except for Vaseline they turn red around the outside of the lips and if I leave them alone they get itchy and they used to almost blister. This happens when I eat too, I have tried tracking everything to see what causes it but nothing stands out. I have found that wiping them with water and a paper towel or napkin helps. I haven't been able to wear lipstick or lip gloss in years. Doctors are stumped and have no ideas. I was wondering if anybody had something similar. My family makes jokes about me being a lip wiper, but honestly that is the only thing that helps. Thanks ladies:)
