Hi i have a small canker like white sore on the inside of in left labia minora. I am not sure what it is. I only noticed it yesterday though. It is white, a little swollen a little red but not that much. Me and my partner had been tested for HIV and syphilis which we both came back negative. I also had the flu for some time now since Wednesday, with alot of joint pain, etc. I am not recovering. I have been using some neosporin on it since yesterday and i think some of the swelling has gone down. I have also noticed that today i saw some thick white discharge, it has no smell or anything but i found it a bit unusual, however i know that i am suppose to have a period soon like maybe next week Wednesday or so.
