I hurt my voice several years back. I was very sick for several months straight, and even after getting well, it almost a year for my voice to fully recover. 

Ever since, I've had some trouble. I've become good at working around it and it has improved over time. However, just a few weeks back, it has taken a turn for the worse. It hurts to talk. I've lost range and stamina. I do singing lessons for hours at a time, and I've had to reschedule them and haven't been able to teach them because of my voice problems. 

Not really sure what it could be.

They're saying it could be a vocal cord hemorrhage (rupturing a blood vessel on the vocal cords), but healing these either requires surgery or weeks of complete, total silence. Neither of which is really an option. In which case, I'll be having issues for months before I'll even be close to being back to normal. If it's not a hemorrhage, it could be nodules or otherwise, but that's unlikely given that I am very careful to avoid techniques that cause those.

I talk heavily for my job, so hopefully it's able to hold up. I'll find out in a couple weeks I suppose.

I never knew you did singing lessons! That's cool!
Good luck! I hope everything works out for the best.
