Any ENT's around or people with experience about the ears?

so I wrote a big post up about ear infections a couple of days ago, it seems my ears were getting the better, they became blocked after I used a netie pot and drove me insane, i still have a ringing in my ear – however my left ear, the doctor told me, had to much ear wax to see my ear drum, my right ear drum was swollen and canal a bit red – so she gave me ear drops which I used on both ears – last night i decided to put some drops of olive oil in my left ear to help soften the ear wax and now I can’t hear!!
Its driving me absolutely bonkers!
I“m guessing it’s the olive oil and not some syncopated extension of a middle ear infection which my doctor didn’t know if i had, i’ve got antibiotics at home now that she prescribed but told me to hold off if it’s getting better – and it is, but now i think i’ve totally messed up my ear, i have a gig in 3 days!!!
help what can i do to clear my ear now!
it feels different than when the other ear was blocked, I can hear myself in my head which I couldn’t with the other ear like when you wear ear plugs, so i’m assuming it’s all because i put the olive oil in my ear which i’m now deeply regretting and hate olive oil because of it – help!!!!

thanks
