I grew up in Arizona and in 2001 I started coughing and was short of breath. Found out I have asthma, am taking advair 100/50, do pretty well except in cold weather, I live in Tennessee now and the winters really hurt me. Ok, started having chest pains upper back pain, somtimes really bad, somtimes its liveable. Could this be from my Asthma or somthing else in my lungs? thanks beverly
