Just a quick note to say I read your chronic cough blurb and it prompts me to ask if you have had a bronchoscopy. I had a chronic cough for two years and FINALLY the Drs scoped me. I was so clogged that I jambed the machine. After that procedure, I have not coughed, but I still have a post nasal drip that I a working on. Email me at ***@****.
