I had a sinus infection 3 months ago. I ve had several throughout my life. I got put on antibiotics and my ear was still messed up. Went back got put on diff antibiotics. It didn t help. My right ear has been ringing non stop and I feel pressure in it. I went to an ent he looked didn t see anything. I took a hearing test and it showed some hearing loss. I ve never had any hearing loss etc before the last sinus infection. I had an mri and the only thing it showed was that my right sinus is almost completely filled with cysts. The dr still doesn t know what s going on. Now he wants a catscan. Could the cysts be the problem? I m only 40 and never had hearing issues. The ringing is making me crazy it s so loud and never stops. I m worried because my dr seems like he has no idea what s going on.
