they have to put on this acidic vinegar solution into the vulva area to see what abnormal cells that are cancer likely cells this is not really bad but it stings a little especially if you have compromised skin. this is the worst part of these auto-immune skin disorders that they can turn cancerous. I get skin cancer checks and make my mum get them as well, but I wasn't expecting all this and its a worry to me because I have been sick on and off now like when my grandfather died I bought home the flu and my lungs really frightened me. someone came into the surgery when I was working with bird flu and my boss was not happy about that and then I got sick and my doctor thought I had whooping cough and I had mris and I was in a lot of pain, I know so was he. but I know his mother hated me. i think they all just wanted to kill me really. but my relatives have never liked me much I know that. its there problem not mine.
