@ameliar Hi there. I had a chronic cough for 11 yrs. It was pretty constant. It annoyed me and everyone around me. I coughed so violently that I'd pull muscles around my ribs, stomach, and back. It was hard on my organs too, especially my bladder. I started treatment at Mayo clinic in 2013 for mac and the cough lessened considerably. Then, I came down with pseudomonas infection in 2016. I was put on tobramycin antibiotic for a month. At the end of that month, all coughing ceased and has been gone ever since. After having coughed for so many years, I never imagined it could or would go away. (bladder problem went away too). Life is good again. Just want you to know that it is possible for you to feel better again also.
