I have developed a sore inside my vaginal canal extending to my inner labia, closest to the area between my anus and vaginal opening. I am in my early twenties and have not had any sexual intercourse for a while, so know it cannot be an std. The sore seems to be getting worse, and worry it may be related to my Merana implant that was inserted around early June or late May of 2012. Could this have to do with the Marana slipping? Or perhaps something else? Most importantly, would I be able to remedy this at home myself with a douche or other treatments or must I see a doctor?
