Hi, RubyTuesday
you mentioned - "Consequently as my symptoms are self induced I'm loath to go to my GP."

Goodness, your poor GP would be out of a job if he didn't have people with self-induced problems to look after. Please see him - or skip straight to an ENT - and get this checked out. You may be pleasantly surprised.

I do understand that it is hard to go to doctors, though. Maybe try this - assemble photos of your dear grandson and dogs - look at them them as you make your appointment, hold them them as you go to your appointment: they will help you remember the beauty and light in your life and give your strength.

Best wishes from our side of the pond!

Maria
