I was just diagnosed with vulvar lichen sclerosis yesterday. I have had itching for literally years and couldn't figure out what was wrong. I knew it wasn't a yeast infection so I just kept ignoring it, thinking I was just being whiney. Well over the last several months the itching became so severe that I was having trouble sleeping and concentrating during the day so I finally broke down and made an appointment. My doctor prescribed some steroid ointment and I have to go back in 4 weeks to be rechecked. She said that if it has not gotten significantly better they will have to do some sort of biopsy or test to see if it is precancerous. She also said to avoid anything that might irritate the skin such as scented soaps, toilet paper, etc. Also, apparently it never goes away totally. All you can do is manage it with medication. Wonderful, huh? So far I haven't noticed any improvement, but I figure I'll give it a few more days before I start to panic.
I hope this has helped. Let me know if you have any more questions or concerns and I'll try to help.
