I've been constantly coughing and cleaering my throat. The problem is that I've been coughing for a really long time like a year or more. I've gotten x-rays but the doctors say that nothing is there. Sometimes it sounds like I have phlegm but sometimes it's just a dry cough. My doctor tried giving me antibiotics but they didn't help. My other doctor who has recently passed away has given me cough medicine but that didn't seem to help either. It gets kind of annoying sometimes because I don't know what I have and if it will stop.
