About a month ago my left outer labia was extremely swollen and irritated. I washed it and wore loose fitted clothing for the rest of the night. I woke up the next morning and it had gone down back to normal. A few days ago this happened again (however the swelling wasn't as bad this time) accompanied by itchiness around my vagina opening. The swelling went away again the next day but the itchiness still remains on and off throughout the day. In these few days I have also experienced minimal white discharge but it is not chunky and odorless. Any advice?
