hi, my mother has had this on going cough for about 4 years now, we keep trying to get her to see our family doctor but she refuses to go, a bit stubborn i know. she works in a dollar store, running up and down asiles, assisting customers and working with alot of cardboard boxes. she keeps telling me that it's a stress cough but i fear it may be more then that she is 54 years old, and i was just wondering if there could be another reason for her cough. she never get head colds, like running nosess, sneezing and or head aches, just the cough. can you help me find a answere or should i urge my mother to get a whole body exam?
