Do i have bronchitis or walking pneumonia? i have had a cough for a little over four weeks. it is mostly wet but at times dry. the mucus is green and at times clear. i have had a slight headache on the left side as well.

Lingering coughs can be caused by a variety of things. The fact that you have mucus and a slight one sided headache may indicate that you have sinusitis. Frequently sinusitis can present without nasal congestion, and the mucus can drip down the back of your throat causing a cough.
