Hello! I apologize for such an unpleasant question, but I gave birth three months ago, I am 19 years old. It was easy without tears, there were just cracks, yesterday after intercourse with my husband, it started to hurt a little bit between the buttocks and the vagina itself, and yesterday there was a ball-like thing right next to the entrance, like hemorrhoids, but directly near the opening, I feel it when I walk, it hurts terribly, like after childbirth, swollen like that, there is no blood, just a pink ball, going to the toilet is painful even though it's not related to the rectum, what should I do, I can't stop crying, I don't want to go
