Have had a cough since Christmas time. It is still waking me at night , I think when I start to breathe through my mouth and it catches on my throat. A bit mucousy but not nasty as you' d expect of an infection. However the cough is now such a deep seated one that it pulls right into my abdomen, I feel as if I have reflux, and a couple of times have felt a sharp pain behind my ribs. It subsides if I straighten up for a moment but is unpleasant . Any ideas either as to what the pain is or how finally to combat the persistent cough.
