Suggest Remedy For Itching And Sore Spot The Vagina

I had an itching and sore spot on my vagina and it felt as if it had a flat bump and my mum had lichen planis and still has it in her mouth and has had it for eleven years but the doctors in England will not give her steroids because of her age and I had some kind of lichen something else the doctor over here said on my ankle for two years and finally steroidal cream made it go away. Now I had a biopsy on my vagina as the doctor thought it was psoriatic exzema what I have on my shins and then said it was pre dysplasia and I should see a doctor in the Pearlman Cancer Hospital just to be on the safe side. Should I think I have cancer there or maybe lichen sclerosis as it is towards the Labia Minora and itches to death at times. But in November I had lice in my head and the doctor gave me medication for scabies and I put it all over my body instead of just my head and wonder if I made myself sick doing it
