2 years ago I had to have a whole term off school as I had problems with my voice. I wss rushed to the top of the waiting list as I am considered to be 'a Professional Voice User'on 5 counts. If you are a PVU you must be jumped to the top of the list so my consultant and Voice trainer told me, it is part of the NHS protocol. Make sure your doctor and your consultant know you are a PVU. Do exactly as they tell you. I was told that unless I did what they said, which included taking time off work, I would never teach again and .. what was far worse, i would never sing again. I was taught to talk again and I was taught to sing again and how to use my voice correctly. Now, they can't shut me up and I am still singing.
