My boyfriend (age 27) has had this all day every day hacking/throat clearing cough with mucus since january. I've been begging him since to get it checked. He waited 4 months until april & finally went. Well, the chest x-ray came back clear. But then why is he still coughing? I'm exhausted of this, not knowing what it is, but hearing it all day every day, anxious beyond belief while he claims he's "fine" when it's not normal.
