Since 2 months I have a feeling that my ears are blocked. At times there is a sensation of bubbles popping in my ears. When I talk my own voice echoes in my head. My hearing is impaired. I simultaneously get severe headaches. I have got my ears cleaned by a doctor, have been given antibiotics, antihistamines, steroids analgesics and nasal sprays. My hearing was tested which was found ok. Finally a tube was put in both ears to equalize the pressure in the outer and middle ear. After all this only the popping sensation has stopped. The other symptoms have persisted. What could I be suffering from.
