Question: I've had a persistent cough for almost 4 weeks now, with no other symptoms. This isn't a lingering cough from a cold, it just came out of no where and has persisted for weeks. It started almost immediately after a camping trip at the beach. The first week of it, it was a tickling sensation that forced hard, dry coughs in fits that I couldn't prevent. Then it progressed to be a wet cough that was terrible if I lied flat, and interrupted my sleep the second week. Then the third week it stopped preventing me from sleeping but persists all through the work day. I noticed that it gets better over the weekends and when I was on vacation for 4 days it almost completely went away. But it came back with a vengeance when I returned to work. I've had (for years now) a wet cough after I eat meals and coughing fits when I encounter cold air (a violent cough that almost feels like choking until I breath through my nose slowly). So this new cough is only exacerbating the problems I have in cold air or after meals. I'm 27 years old, a healthy weight, and have no other health issues. Is this allergies? Asthma? Viral? I'm so confused.
