Having ear disorder causing me uncomfortable sleeping

Hi doc, I’m 26 male. I’ve been having this ear discomfort whereby initially one of my ears (left ear) was having some sort of stinky yellowish sticky fluid (probably pus). Few days later, I started to experience ear pressure problem where the infected ear was having some kind of stuffy feeling which I can obviously feel that, causing me discomfort sleeping due to pressure in that infected ear.

I did consult several polyclinic doctors and they just provided me a normal ear drop, which initially was helpful. About 1-2 weeks time later after applying ear drop, my ear was having this yellowish discharge again, and once again creating the ear pressure discomfort. I went to consult general hospital ENT doctors, and eventually they concluded that my infected ear was due to bacterial infection. So they cleaned my infected ear, and right after cleaning my infected ear, I was getting back my normal hearing without any ear pressure discomfort anymore.

Again, as I thought I was fully recovered from ear discomfort, exactly 2 weeks later after having my infected ear cleaned which I’ve mentioned earlier, I started to experience back my hearing disorder with exactly the same ear pressure discomfort. I could not sleep well. Any opinions on why is this happening and any recommendations on how to treat it properly? I need help, much appreciated.
