Thanks you've all been a great help. When I metioned that the doctor told me to rest my voice, he didn't look at my throat, or even seem as though he was really listening to me, as that particular visit to the doctor was about a more serious health issue and i just happened to mention my voice.

As to above about my colleagues - i have a scratchy voice most of the time, so iassume that they think thats just how my voice sounds. You hit the nail on the head with why i havent told anyone there - I dont want to risk my job!

I've booked another appointment with my GP and i'm gonna be a bit pushier to get something done! Thankyou very much, all of you who have commented - your help is greatly recieved!
