My left ear is clogged up. I had a November sinus cold, throat/cough. Was on a puffer, cough gone. Given nasal spray & used it. Took Sinus tablets for one week. Still hearing hissing, clogged up ear. I pinch my nose & blow & breath to pop it & I hear a high pitch sound as if you popped a balloon with a needle & then there leaves an echo sound in my ear - still clogged. Sometimes eases off during the day, is getting better every week but has not cleared up. Was on antibiotics Amoxicillon - kids dosage for 7 days - 250 mg 3 times a day and have finished that too. Hissing sound periodically thoughout the day as well. It is bothersome, not clearing as fast as I thought it should. Family Dr. states if by mid January it does not heal, to see a hearing specialist as it takes one year to get in to see an ear, nose, throat specialist. ? Should I get an MRI?
