This is (unfortunately for me) just what I need to read right now.
I'm an amateur singer and I teach children cycling proficiency - and over the years I have got louder and louder - mistakenly believing I needed to project my voice for the children. my voice has become deeper,and though I do sing low harmonies I have noticed some discomfort. While reading through this ten year epic thread I have tried out a few breathing suggestions and must put them into practise. I have also noticed more discomfort as I swallow. I had an uncomfortable time having an endoscopy last January (not an investigation of my throat )and ended up needing sedation for the procedure. With my current problem I've had my thyroid level checked and it is fine. Now I am due to have and ENT appointment this month so I'll revise the above info and go 'armed' with questions!

Many thanks for all the advice. The food and drink comments are most interesting. Let me grab the blender.
Wish me luck
Hazel.
