What Causes Vaginal Sores?

I am 25 years old and am experiencing vaginal sores. A little backstory about two years ago I had a couple sores in my anal region I immediately had them tested and everything came back fine. Even the doctor said she was pretty sure they were not herpes.fast forward to now, about two weeks ago my partners and I had pretty rough sex and at one point I began very dry and we both had areas that became very raw. His healed in about 2 days but I noticed the bottom of my vagina was very red and inflamed. I often experience a small tear in that area after sex. In the next couple days after I was still very sore and started to noticed some sores. They didn t look like typical herpes but the ones that are in my inner labia are pretty tender and raw I m guessing due to the moisture. I went to the doctors and was told I have both a yeast infection and bv. I was given a single does of fluconazole and clindamycin to take for a week. I feel like my symptoms are not improving now sometimes when I pee the pain is excruciating and I m noticing a milky discharge that I didn t have before. At this point I m really scared and confused and waiting for the results is torture.
