Suggest Treatment For Painful Lump In The Groin Area

Hi I have what appears to be ulcers near on my vagina at the top in the fold near the urethra where discharge tends to accumulate. I had what I self diagnosed as a yeast infection which I get all the time. I am also prone to uti as well. The pharmacy recommendation was emla cream to numb the pain so I can function and pee which is not helping. I cleanse area daily with coconut oil and tee tree oil as water is not slippery enough and hurt..was told no bath as yeast likes warmth. Please what can I do to heal the sores they are the worst pain I ve ever felt. I have been tested for stds very recently so that is off the table. I am still taking canestent so I need to wait to finish to go to my Dr she said as that will alter results to see if it is in fact a yeast infection that ate away my skin.
