Ive been sick since august and getting concerned. ive had an unproductive cough which feels like sticky mucus stuck in my chest and fatigued. i was on mucinex, zpack, steroids and albuterol with no avail?

You need to see a lung doctor for a full evaluation. Have you ever smoked? Are you short of breath? What was your occupation? You may have chronic bronchitis but you need a full evaluation to find out. There are also other conditions that need to be ruled out. A CT scan and pulmonary function tests would be a good place to start. So, see a lung doctor. Good luck!
