Hello, So for quite a while now I ve noticed that I get a diaper rash when on my period due to the pads. After a little while not on my period they clear up and go away. Except one time perhaps 2 months ago, I noticed a lump form between my vagina and rectum. It s almost numb, there s no feeling when I push on it, but it s giving me trouble. When I sit down on the toilet it sometimes splits which hurts then bleeds a tiny bit. Also when ever I go to the toilet to poo, as I wipe my bum it s hurts to wipe due to the lump. There s also a tidy bit of blood from where the lump has split. I ve also noticed that around the hole of my vagina it can get itchy as hell, but if I itch too much it bleeds. One time my vagina crusted up (where I scratch) I have no idea what could cause the lump and itchyness that came along it. I ve searched all over the internet, it doesn t appear to be sti/std or scabies? But perhaps I could be wrong. I m also 18 and sexually active incase that helps.
