I see on the postings that a couple of people started having problems about 2 years ago. That's just about when my sinus problems started as well. My left sinus drains all day and night. I do live in the mounts where the weather is dry as well as having pine trees which can be a problem. I have a cough that is persistant all day as well as through the night. About two years ago I had a really bad flu returning from Hong Kong and then I lost my voice. Side note: I do lots of traveling for business to Hong Kong, Mainland China, Vietnam, Korea, Taiwan and Germany. Not sure if this could of caused the problem as well.
I too went to and general doctor as well as an ENT. He mentioned that I had a deviated septum and he asked if I had breathing problem, which I told him I did not. When the drainage hits my vocal cords I start coughing and loose my voice. Has anyone else experienced this?
Cold, damp weather seem to start the coughing more than other times.
