I even have the bomb of nasal sprays called Avamys which most GPs won't prescribe at all nevermind long term (mine did, she agreed it was better than episodic use post infections) and while hot drinks help, it's pretty deep damage.
ENT wrote to my GP (they used to work together) and effectively said "It's fucked, nothing we can do, fuck off and manage in primary care cos we aint got any better answers!". GP always used to laugh at my paraphrasing as such while I directed her to where to find it and would say "yeah, you're not wrong". Am lucky the GP practice as a whole groks that I have a very unusual history and work with it.
I'm giving it till tomorrow, and if no improvement, will see a GP. I usually leave it slightly too late, but it's a tricky balance when they're supposed to follow NICE reccs and my case isn't ideal for that.
