A year ago I was able to sing what I want and my voice was nice. One day my voice changed and did not come back. 3 doctors checked my vocal cords and other things, and all results were good (I also did a C.T scan). No one found the issue why my voice has changed and why I can't sing anymore. So is it because of a bad technique or will I lose my voice forever?
