Sinus infection twice followed by sneezing, runny nose chest pain swollen glands, hacking cough with thick green, white, dark yellow mucus. Cold?

Probably sinus. Your history suggests that you may be suffering from nasal congestion (most likely from allergies) leading to obstruction of the sinus drainage and then infection. Controlling the nasal congestion would be the first step (visit an allergist?). Later on a CT sinus and/or immune work-up may be pursued if indicated.
