Recently Diagnosed... I want HELP...

I have been itching for a while now. The doctors thought I may have had displaysia of the vulva (bc my mother had it), but then realized it was Lichen Sclerosis. I had a biopsy taken and it's positive for LS. The symptoms I have are itching and the color has changed to white... and the inner lining of my vagina on one side has decreased.. almost gone. I didn't think I had a disease, I'm 20 years old and started having sex at the age of 18 and thought it was from sex... so thought nothing of it. I've been to the doctor a few times and have been treated for yeast infections and bacterial infections.. and they just now realized I have the LS. My doctor is putting me on a steriod cream, so hopefully that will help. She said it will prevent it from getting worse. I've looked at some pictures of LS and I SURE HOPE mine doesn't get like that. Do the steriod creams really work is what I want to know? I'm scared and am not sure how to go about this skin disease. Will I be able to have sex in years to come? Where is a good site to find good information on this? Tweet
