Morning cough - different positions produce different coughs
Every morning for about the past 6 months, I wake up, and I feel the need to cough to clear my lungs. They feel full (liquid-y), but the cough itself is not productive. It is very benign and boring-sounding.
Only when I roll over onto my left side and then cough does it turn into a heavy, loose-sounding cough, and my lungs feel like they are clearing themselves finally. Each morning I know to do this, as it is the only way I can get some relief from the full feeling in my lungs.
If I roll over onto my right side and cough, there is no loose-sound, but instead there is a deep barking seal type of sound. When I cough lying on my right side, I can't help coughing hard and deep and this results in my lungs becoming irritated and making me cough even more.
Once I return to my back, the cough turns into a nothing, bland cough again, and once I actually get up and out of bed, the cough goes away entirely within 10 minutes.
Is this really weird? Why do I have totally different sounding and feeling coughs depending what position in bed I'm in??
