I'm not in a very different situation. About over a month ago, almost two, I had a terrible cold and cough. Since then and till now I've had a blocked ear. Doctor thought it was sinusitis but the x-ray proved it wrong. I'm right now just using sprays and a tablet to try and make the mucus stuck on, possibly, the Eustachian tube liquid and cough it out but it doesn't seem to help. It does also cause a "ringing noise" in my ears.
