Hello, I've had vulvar itching & irritation (but no burning at urination nor discharge) since March (4 mos now)--constant, but worse at night. 5'8" / 175lbs; not sexually active. Visited general physician and had numerous tests--negative for everything including BV, stds, etc.; pap was normal. Blood tests showed slightly high folic acid. Dr noticed genital mole that is new, but said it looked benign. No recent changes in lifestyle, diet, or hygiene. I was told to use vagisil, but it only offers minimal relief at best. Also, had horrible outbreak of canker sores last week (never experienced them as badly before); I do not know if this is related.
