Hello, I have one sided hearing loss. I did a pure tone audiometry and left side showed hearing loss. Bone conduction test showed normal values which can be seen in the graph attached above the air conduction graph. I did have recent flu three weeks and ago and still a bit of cough. I wasn't able to pop my left ear. It pops now but slowly and after popping I still feel pressure. Right ear after popping opens up and I hear better. During the flu I started hearing my own pulse in my left ear which has gotten better as I started feeling better. What would be causing this kind of hearing loss? I am not able to upload a pic but the bone conduction has all frequencies above 10 db and air conduction in left ear at frequencies of 750hz and 1000hz is at 45 and 50 db.
