I ve had a cough, stuffy nose and sinus pressure for a week now. I thought it was allergies as my mucous was clear. One day into my sickness, I coughed up what looked like a pea size ball of firm...food? or something. Ever since then, I have had a horrible productive cough. Sometimes the expectorant is whitish in color, but occasionally I will get a greenish one. Yesterday I noticed a foul odor when I cough. It s ONLY when i cough. I ve not ever had fever or anything nor do I feel bad, but it is possible I could have bronchitis or something? Does it just run it s course or should I break down and go see the doctor? How long should I wait it out?
