Thanks, and cherlyd as i said i was sched for appointment at the hospital but by the time is came through (1 month later) i had move. I called them and they said i would have to be referred again. Which meant i needed to go to the dentist/docs again and get that referral.

I probably had it 2-3 years i certainly cannot see any difference in the first time i saw it, just a white patch with like a purple outline (depending on light).

Thanks for assurance will keep posted, dentist is on monday then its however long it takes for referral again
