Discussions that mention thyroxine

General Health board

Hi Thank you for your reply, No i do not take anything for high blood pressure I do take thyroxine for an underactive thyroid. Could this not possibly be post nasal drip or is is not possible for that to go on for over 2 yrs. I must admit at first it was just a dry annoying cough for about a year, then it just got slightly more and more but i know it was roughly 3 yrs ago now that i asked my doc about it. Also how can a cough be heart related??? At night when i really get going with the coughing i can feel my heart racing and thumping and i get breathless but that is because i have coughed so much for hours, it is exhausting sometimes.
