Without wanting to intrude, still I am curious as to what the specifics of your problem are--I lost my voice completely due to a voice strain about 10 years ago--had an exam done by a specialist(the most unpleasant part was the specialist himself, if I'd brought my guitar, I would have hit him with it) who told me that I had developed nodules that would affect my voice from then on--

For other reasons, a few days later, I saw my homeopath, who noticed that I could not talk, and gave me Spigelia--After a few weeks, my voice returned, and, within about four or five months, the buzz from the nodules was totally gone--

I was playing in a band at the time, and, when my voice went, the other guitar player did all the singing(his own songs,of course), at which time I realized that I really didn't like playing his songs--but that is another story--
