Hello, I am Madhu, a 35 year old woman. For more than a month now, I ve had a cough on and off.Initially I ignored it. Then I started to take OTC - Actifed Cough & Cold. It was effective, but as soon as the medicine wore off, the cough returned. It started to get progressively more severe, with a wheezing like sound accompanying. Finally I went to a doctor here. He put me on an Azithromycin course for 3 days - 1 tablet every day and also Diphenyl cough syrup for 5 days, 5 ml thrice a day. Also got an X ray taken. It says Prominent bronchovascular markings noted . Everything else in the XRay Chest PA view is normal. After I finished the medicine course, the cough returned, it hasn t yet disappeared completely, and a couple of nights ago had a particularly bad time. Was forced to again take Actifed Cough and Cold, which immediately was effective. Last night was ok. Now I m worried as to whether this cough will ever go away completely or not! I occasionally cough out / blow out of my nose yellow flem. Would you be able to explain this extremely annoying issue?
