5 years ago, I had sinus surgery to unblock sinisuses on one side and remove polyps. Since then, I have had chronic post nasal drip and coughing from it. I have constant drainage and ear problems and sore throat. I have tried, the nasal steroid sprays, nasal washes, and nothing really stops it. I'm never sure when the uncontrollable cough from the tickle from the post nasal drip is going to hit me. Sometimes I have been afraid I wouldn't be able to catch my breath because of the excessive tickle and coughing.
