For over a week I've been pretty much deaf in my left ear and hearing a high pitched beep. Feels like I'm underwater. I've been putting otex drops in but don't get any fizzing/bubbling and there's been no improvement. So I'm thinking it's not earwax that's built up. Dr google says it might be a blocked eustachian tube? Has anyone had this? Will it ever go away? It's driving me mad and I've got an important meeting this week. Do I need to see a doctor?
And advice gratefully received, thanks!
