As anyone who experiences either of these symptoms knows, they're much misunderstood & underestimated.
I have experienced pain in my larynx for over 18/12; because it's there every day to some degree you don't mention it, or you'd sound like a cracked record, but it is draining.Feeling like there is something prickly in your throat, is a pain, literally especially at night when you're trying to get to sleep. If I overuse my voice itfeels like someone has had a rasp down my larynx & trachea.
Some things which can help:-
-sipping water - never try to clear throat by costant coughing
-steam inhilation, especially before bed,
- chewing gum, to help relax larynx
- trying to speak, in such a way that you feel a buzz in the cetre of your face - eases strain on larynx
-yawning & or what you call snigger - a closed mouth smile - helps adjust angle of larynx ( Latter useful as an emergency measure)
Any other tips gratefully received.
