I have seen 3 M.D.s for a problem with my left ear. All three have told me there is nothing wrong with my ear. I have a lifelong history of allergies and asthma and also have had three sinus surgeries, one to remove polyps. The third surgery the Dr cut the tear duct in my left eye which resulted in an eye surgery.i have recently finished my third round of antibiotics for chronic sinusitis. The last Dr. told me to hold my nose and press on left eye to open eustation tube. This hasn’t worked. I have tried ear candles, otc ear drops and debrox drops followed by rinsing with a bulb syringe. I have no pain just a constant noise in my ear. Any suggestions?
