I've had a pretty nasty sounding cough for over a month. Smoking and post-nasal drip are perpetuating it. It's productive, but not funky in color and I don't have a fever or chest pain so I don't need to see an MD. Taking something OTC would clear it up, but I'm so afraid to take anything with the meds I'm on and because my bp is so brittle. I think I'm going to buy something when I hit the pharmacy to pick up my prescriptions though. It's been long enough.
