Thank you SO MUCH for responding! My symptoms have been a severe cough for over a year. I've noticed when I get hot (post menopause), I will cough so hard I have cracked my teeth according to my dentist. I never cough up blood but struggle to bring up mucous. This will happen several times a night and as a result, I'm not getting quality rest/sleep. I have been on hormone therapy for 5 years so it's not just that. If I'm doing any chores and overheat, I almost cough up a lung, no pun intended. It's been bothersome to say the least and I've pressed my doctor to pursue this further. Because my chest X ray came back clear at my annual physical exam in January, he didn't think anything was wrong!
