Hello everyone. My problem started on 1st of August when I had pain in my left ear. I took some ear drops and some pain relief but by night I had fever so I went to the emergency room where they gave me amoxicillin and oxucodone (I didnt take that. I thought it was too much). I continiued with amoxicillin and ibuprofen. Eventually the pain went away along with the fever. By August 4rth and while I was feeling better I realised a small ringning in my left ear. I went to an ENT and he told me that indeed I had a middle ear infection, he cleaned my ears changed my ear drops and told me to keep taking everything untill the infection clears up. About the ringing he told me that it will go away. After a week I returned to the doctor. No infection any more but still some sensation of blocked ears espacially when I moved. He told me there was Eustachian tube dysfunction and gave me two nasal sprays (Avamys) to use for the next 4 weeks. In the mean time I had a long flight (actually two). I took all the measures I could and had no problem at all with the flights. Now 28th of August the ringing is still there ( I can only hear it when i close my ears or in my pillow) along with some hissing in both ears (like a tv) that sometimes go up. No problem in sleeping. The strang think is that the ringing is a bit louder in my healty ear. I still feel some pain for a few seconds in both ears and sometimes pressure in my left ear (the one that originally had the infection). I did some hearing test. No problems found there. (I wonder if there are more extensive hearig tests than that). My eardrums seem fine. And that is pretty much it. I really wonder if there is actually chance for the ringing and hissing to resolve after almost three weeks already. Thank you very much in advance for your answer.
