Hi, Since A Couple Of Months I Have Tearing Between

Hi, since a couple of months I have tearing between labia minora and majora. But only on the right side!
I don't have discharge or itchiness. Just a bit painful on touch. I tried over the counter antifungal creams but it didn't go away. Applying vaseline seemed to help but then the cut came even stronger. The cut is a couple of centimeters long. I avoid any possible irritants and wash only with cold water.
