My family has dry cough &sinus stuffed up but i'm wheezing and coughing up green mucus & feel weak & tired what could be wrong can't afford to go dr?

Wheezing/Cough: Feeling weak and tired with coughing up green mucus is concerning for infection, somewhere. Wheezing would suggest the lungs. Could be asthma exacerbation, bronchitis. Could also be a sinus infection since the nose/sinuses are "stuffed up." most often for infections of the sinuses or the lungs or airway, you might need antibiotics. Try a nurse practitioner, they can diagnose &treat for less $.
