So after 3 days of complete deafness in 1 ear and being quite deaf in the other, plus a horrible feeling of bunged up ness in my head, plus my balance going a bit, I got a syringe kit on Amazon Prime (like Curvatures link above).
Filled the sink with warm water, and after about half a dozen syringe fulls bits started appearing in the sink. Then more bits, and more until the bottom of the sink was quite well covered. Then -pop- my hearing came back!
I rushed downstairs to tell my wife, who wasn’t as overwhelmed as I was, and didn’t want to see the contents of the sink.
However I still felt bunged up so emptied the sink and had another go. Plenty of bits again, then -relief overload- a bit the size of my small fingernail plopped out!
So left ear sorted, hearing like Superman and head pressure gone. Tomorrow I’ll do the other ear.
Anyway the syringe worked a treat and was only a few quid. However I’ll do my best to use the drops from time to time to avoid all this. Or at least to avoid phoning the taxi firm and asking for the nurse 😁
