Scarlett - you dont say that you have been to the doctors, but I'm assuming you have. Go back and make sure they refer you to a specialist. As a singing teacher, you just cant risk damage to your thoat by letting this go on too long! Demand a second opinion if you have to!!!!! You really shouldnt be trying to teach when it's as bad as it sounds, you are only doing more damage!! Your doctor should be giving you a letter for work to excuse you from "verbal" duties. Look after your voice girl, it's the only one you have!!!!!
