I am wondering about a cough i ve had for a year and a half. I take clonidine, metoprolol, lasix and azor for high blood pressure for some years now like 6. I had a pericardial effusion 2 years ago. Something is making me cough. Its clear and constant and interferes with my sleep and days. I am also a peritoneal patient. I wonder having my pericardial effusion, to drain the fluid from around my heart, where does the fluid go now in my body and could it cause me to cough if its coming up from somewhere to my throat. I tried omitting the bp meds, but don t think its that. I have also been treated for GERD. But I dont have heartburn, just fluid that comes up and makes me cough. It hurts to cough and im hoarse and my heart even hurts from coughing every single day.
