Tried the onion thing twice, didn't do much of anything - the thing with that too is you have to drain it/clean out after an hour too as it can risk creating some food for the bacteria too.

Day 4 on antibiotics and not much progress on unplugging my ear, but at least the pain had dulled down a bit. 

 Oh no sorry, I'm glad the pain has dulled a bit. Have a look at mullein and clove tea. Clove is a natural antibiotic and mullein is very good for congestion. There are also things like colloidal silver. I'm off to bed now but hope you feel better tomorrow.
