That's what we're all using, except the few who have Protopic, or who are refusing clob. You have lichen sclerosus over tht big an area? I looked 'extragenital LS' up and found this bit on The British Skin Foundation (as information for any LS sufferer who may see your post):
What is lichen sclerosus?
Lichen sclerosus is a relatively uncommon condition in which thin white crinkly patches appear on the skin. It can appear anywhere, but is most troublesome in the genital areas.
What are the symptoms of lichen sclerosus?
Many patients have none, but the most common symptom of lichen sclerosus is itch. As a rule the spots on the general skin surface seldom itch much, but those in the genital area do, and can also be sore if the skin breaks down or cracks. In the genital area, the scar-like process can tighten the skin, and this can interfere with sexual intercourse in affected men or women. In men, lichen sclerosus can make the foreskin tight and difficult to retract, and can even partly block the flow of urine.
What does lichen sclerosus look like?
On the main areas of the skin, the spots of lichen sclerosus look like small ivory-coloured slightly raised areas, which can join up to form white patches. Some have tiny yellowish horny plugs within the pale areas. After a while the surface of the spots can look like wrinkled tissue paper. The most common sites are the bends of the wrists, the upper trunk, around the breasts, the neck and armpits.
Most of us are willing to use Clobetasol, which is thousands of times stronger than over-the-counter steroid creams, because we're afraid of our vulva shutting right over the urethra and because having chronic open lesions in a location that constantly gets doused in urine – there's a larger than average chance of developing squamous cell cancer of the vulva. I have psoriasis, sometimes on large areas, and stopped using steroic creams on it over a decade ago, because it usually just goes away when the stress in my life calms down.
Does your dermatologist know you're using clobetasol over large areas? If you were using way too much you might get symptoms like cushings syndrome – puffiness that causes moon face.
