About six years ago, when I was in high school, I got involved in an incident in which a fellow student wrapped his arm around my neck from behind in an apparent attempt to black me out. While I didn't black out, I believe that this did cause significant damage to my voice. For a week after the incident, I felt pain in my throat. And ever since then, I haven't been able to hit high notes, my voice becomes hoarse and cracks randomly, I can't speak softly without whispering, I feel a slight strain when I talk, and sometimes I have to make my voice deeper just to avoid whispering. Prior to the injury, I was able to hit high notes regularly while singing and was even able to falsetto. Now I can nowhere near hit high notes and when I try to do so, it causes severe strain on my voice. I plan on making an appointment with an ENT specialist, but want to learn as much about my situation from others who are familiar with something similar. Since the injury occured six years ago and has been left untreated, how likely is it that my inability to hit high notes, hoarsness, etc. is permanent and that I will have no help from surgery and/or therapy?
Thanks everyone for reading.
