The past week I've had a cold. As the week has progressed I started wheezing and developed a barking cough with some phlegm and twinges of chest pain. Constant barking cough, inconsistent wheezing and chest pain. Also expierencing some dull pains in upper right back for about 3 weeks. My concern is if I could have bronchitis? Or if I should be worried about something worse? I should add that I used to be a smoker and i recently quit. No history of lung cancer or really any cancer in family
