I have been coughing up phlegm every morning for about a week now and i have some wheezing / chest tightness in the morning. I am 36 years old and have been a smoker since i was a teenager. I cannot inhale a cigarette without coughing horribly for about an hour or two after i wake up. I have never experienced this before. It seems to get better throughout the day and i don't have any other symptoms. Should i see my dr.? Do i have an infection, allergies, something else?
