Hi, I'm 20 years old and Ive never had sex before. The left side of my vagina started to swell a couple of days ago, and now there is an unbearable pain constantly in that area. I have recently joined the gym and it has been a while since i had gone, i read a strained muscle might be the cause, but im not entirely sure. I also shave down there as well, and i think that may be the reason behind swelling. this has happened to me once before but it eventually went away within a couple of weeks. I just want to know what it is im dealing with.
