Hi, I have had a constant harsh cough for 3+ months, I am not a smoker, nor is anyone in my household or work smoke. I occassionally have a slight productiveness with this cough with clear to whitish phlegm. I have never had seasonal allergies or a history of asthma. I have during this same time started taking Topamax 50mg at bedtime to help relieve serious chronic migraines & I m happy to say this has really helped. I am 62 yrs old and over weight but I would not consider myself morbidly obese, I have lost 15 lbs in the past 3 months as well, but this was intentional. My only other Heath issues are controlled HTN and GERD. I would like to stop coughing all the time, as an Oncolongy RN it can interfere with the care of my patients. Thank you.
