PV , I live on an Island and have to wait for visiting haematologists every three months , my lovely GP doesn't know much about PV, so no point in asking for info there, I also have an horrendous leg rash since being diagnosed 4 years ago, no-one can tell what it is, the itch from it is really bad. if I had a sharp knife I feel I could cut the skin off it gets so bad. I have had every known ointment /cream to rub in but nothing works, UVB light treatment also and biopsy's but all I got from the Skin specialist was a shrug of his shoulders and him saying well I don't know the cause. Rant over and I will just have to put up with it. hey ho at least I'm alive.
