Three weeks ago I had super rough sex, and the next few days I was super swollen and I had tears in my vagina. After awhile, the pain was gone and every thing felt back to normal. Just a few days ago my vagina started to itch inside for a few days and then it stopped. Over this weekend, I had a track meet in the hot sun and ran a lot and the next day my vagina hurt really bad. I put a mirror to my vagina and there was a swollen pit of redness with blister-like sores inside of my vagina on one side. My partner used a condom and he does not have any std's or sti's. Today my vagina hurt, and started to bleed and now the pain is gone. What could this be??! Please help
