Struggling with Hearing Loss and Ear Problems

So I’ve had troubling with my ears & sinuses forever. I started seeing and ENT March 2021 & had an adenoidectomy in June which I figured would help some ear problems. Here we are January 22 & it really hasn’t. My doctor is stumped. The hearing loss didn’t show on the hearing screen but I absolutely cannot hear as well out of my left ear. I’ve been struggling with dizziness and fullness in my ear. The doc did a 2nd myringotomy (hole in ear drum) a few weeks ago then I had a CT scan to look for abnormalities. She said there’s a fluid buildup in my ear but can’t see it from the outside so I made need to see an ear surgeon. Has anyone experienced anything like this? What has worked for you with hearing loss that doesn’t show on a hearing test? Thanks 💕
