A couple days ago I was walking around alot and it was hot outside, so I was sweaty. I noticed that after a while my vaginal area started to get quite sore, however, I did keep getting wedgies that I obviously couldn't get rid of in public and no way to privately remove them. When I got home that night, my vaginal area was extremely sore and red. Would this be from possible chafing or a yeast infection or something? How do I cure this? It's mighty uncomfortable.
