When your doctor says you have bronchitis, otherwise it's your guess. If you're coughing up a lung go get a antibiotic if you let it go to long & your bodies lost the war-pneumonia is just around the corner. High temp. coughing, no energy, sore throat green/ yellow mucus-
I have had it several times. If you exhale deeply at the end of this you may hear a snap, crackle and pop wheezing sound. Seeking medical help is prudent in any case if you are coughing and short of breath. Don't wait to get help. When I finally went to my Doctor he said one more day and he would have put me in the hospital.
