Hey guys, I am 25, a semi-professional singer/musician, and I am very social and do talk a lot. I have been having the exact same issue for about 3 years now. It began when I started doing a lot more traveling gigs and also began using my voice in a different method to get a desired raspy, breathy sound. The vocal sounds I was making were amazing! However, after several months of this, I lost my voice completely for 6 weeks. Then, after not singing for 4 months, I finally got back to where I could sing. I thought it might have been acid reflux, allergies, polyps/nodules, perphorated esophegus (At the same time as losing my voice I get this pain towards the bottom of my throat/top of my chest), or tonsil issues. I have had a nasal/vocal chord scope, video stroboscopy, upper EGD, voice therapy, and even had my tonsils removed! (Which mind you, as an adult is extremely unpleasant)...After getting my tonsils out I couldn't speak for about 10 days. After which, my voice felt pretty good. Then I began singing again. Everything was good until I started singing raspy again. Then, the same pain and loss of voice. I HAVE ABSOLUTELY NO DOUBT IN MY MIND NOW THAT MY ISSUE IS BAD VOCAL/SPEAKING TECHNIQUE. While I did do speech therapy, it was only 1 day a week for an hr, and I wasn't very good about doing the homework. I am now going to begin Speech Level Singing lessons, which I believe will be even better than the voice therapy. I will also check out voice-doctor.com as Jeff 123 suggested. Guys and gals, I understand your frustration, maybe even more as this has interfered with my career as a musician greatly over the last 3 years. It's even made me depressed as I want to talk to people, but it hurts to, and that just sucks. The issue here for probably most of us is poor vocal/speech technique, we are just hoping there's an easier fix, a medical fix where we can take a pill or have a surgery instead of re-learning to speak.
Good luck all.
Luke
