Hi Robin, sounds like your GP doesn't really have a clue. I have LS, and it doesn't present as thickened plaques of skin, that sounds more like lichen planus, which I don't think affects the genital area. LS typically presents with areas of smooth whitened 'pearly' skin, which may be thinner and more delicate than the surrounding tissue. In advanced cases you can develop a build-up of scarring, because the thinned skin tears more easily. It causes intense itching and irritation and needs a course of steroid cream to get it under control. You need to go back to your GP and insist on being referred to a specialist - your GP can't diagnose it definitively because it needs to be done by biopsy. Good luck x
