I've recently split up with my boyfriend and been feeling really low. I haven't been eating properly and have been ill for nearly a week. In the last couple of days 2 ulcer type marks have appeared on the lip of my vagina. There isn't any puss but its sore and looks horrible. A few months ago I was tested for STD's and was clear so wasn't sure if this was related to my body being run down. I've had a look at genital warts and it definately isn't that. Can anyone help with what it might be? How it can be treated? or if I need to see a doctor?
