i ve had this cough for 3 years. sometimes there is a crawling sensation in my chest and other times it feels like a tickling at the pit of my throat . Everyday I cough. Somedays I cough more than others. the cough begins dry and becomes productive with clear frothy mucus before the cough attack is over. after the cough attack is over i find myself clearing my throat for the next 20-30 minutes because of drainage. My chest gets tight and sometimes my throat does. there is not certain times that i cough. i cough day and night. alot of times i cough after i eat, when i lay down, when i get hot. often i have to get up and walk out of church 2-3 times during the service to finish my cough. drinking water and letting cool air blow in my face during these attacks seems to help but does not stop the cough.
