Swollen

Emmi

So I haven’t had sex in about 3 weeks. After I did my vagina was swollen so I got tested and they said I was clear and it’s probably because of like roughness. So I ignored it. But now out of the random my vagina swells. It hurts to walk or sit with my legs closed but it only is there for like 1-2 hours. I just need some advice from someone who may have also experienced this.
