When i use to sing i could get my voice pretty high, Playing Football about 3 weeks ago I was hit open handed in the bottom of my throat, I was gasping for air for a good 30 seconds- 1 minute. Afterwards i could not talk and it hurt alot, i went to emergency and they had a look and said there was no damage, it was probably just a muscle spasm after being hit to protect something in my throat. Still three weeks later I cannot sing high, every time I try go high it just wont come out, and then the bottom of my throat feels like there's something in it. Will i ever be able to sing high again or is there permanent damage?
