I have a deep tickle in my chest that I can t seem to scratch with the cough it is causing. The cough is very deep an causes my entire torso to convulse as tight as it would for vomiting . I do cough mucus up, but not every time. I have no headache, runny nose, congestion, ear ache, sore throat , or drainage. Should I be concerned that it is more than a cough? Again, the tickle is not in my throat-it is in my chest.
