Hello, for about 2 weeks now I have had a problem with my throat and voice. I am a singer and 1/2 of my range is completely gone (upper range), when I try to sing, my throat tightens and no matter how hard I try I cant hit the note (a note which normally is very easy for me). Normally when i cant hit a note my voice just cracks, now it doesnt even do that, it just stops and goes very flat. Sometimes it almost feels as if I am chocking on my throat if i try too hard. Any Ideas for me? Thanks a lot!
