For about 4-6 weeks, I've been experiencing irritation on a specific portion of my labia majora - if you're standing up, it's the bit directly facing the floor. It feels a lot like chafing or dryness (with occasional mild itching), but it's not especially red, and it looks normal. No pain anywhere else or weirdness anywhere else, though I had a weird amount of discharge/possible bowel leakage for two weeks around Halloween, which has since cleared up. I'm a 27-year-old cis woman, not sexually active, and have only had one previous sexual partner six years ago. Plenty of normal gyno visits since.
I first noticed the chafing feeling after I'd started biking more (I've since stopped) and started wearing tights almost every day because it got cold outside. Other things that had changed in my routine at the time were I tried a new personal lubricant or two (also stopped using that five weeks ago), went a little germophobic and used too much detergent for a couple loads of laundry, started wearing pantyliners almost daily, started a job with really cheap toilet paper in the bathrooms, and tried a new brand of underwear.
I feel like it's probably one or more of those things, but since it hurts just to touch it, and is generally a pain in the neck to deal with, I figured I should see if anyone has any other thoughts.
I'd go to the doctor, but my insurance won't cover a thing until I hit my deductible and I'd rather not go until my wellness exam in Feb unless I have to.
