Talk to Ent Specialist on Difficulty Hearing

I once got flue and felt lik plugged ears , it was unnoticed until i really felt was having difficulty hearing soft sounds, visited doctor they said it's wax , I got it cleaned, but even then I was having difficulty hearing soft sounds , it has increased with time, I consulted ENT specialist, first they said it's otitis media effusion, but later after complete check up ,they recommended using hearing aid, as I had no apparent signs of infection , prob was in middle ear. Now my prob is, with time it has increased so, I feel like I'm going towards deafness, now I hear blood flowing sound in my right ear at night too , My question is is there any solution.to this ? Any treatment, I want any specialist doctor who could help me with this Thanks in advance
