Hello, I'm new here. I am meeting with a young lady tomorrow who, as I understand it, has been occasionally loosing her voice for around three years now. Since I don't know all of the circumstances I will be checking out head or neck injuries at the time it all began. Perhaps acid reflux problems of which she may not even be aware. I was told that when she was a child she suffered from ear infections, had tubes in her ears, and was on antibiotics for over a year. Does anyone know if a dairy allergy can cause occasional loss of voice? Any other ideas?
