Have had a cough for a couple of weeks, but in the last few days, it has become relentless, often ending with vomiting. Had my chest checked 5 days ago, dr said it was ok. Have been using ventolin and pholcodeine, but now i am exhausted, as it is physically hurting and preventing me sleeping. It is far far worse at night. I am sleeping virtually upright.
Why is it worse at night ( evening, even before I lie down) and is there anything else I can do to relieve it?
