I've Been Fighting A Bronchial Infection For A Month Now.

I've been fighting a bronchial infection for a month now. 1st visit to after hours care center, given 5 day z-pack, steroid injectin, 3 days of steroids and benzonatate. I took all meds and never cleared up. 2 days after med completion ended up back at after hours and given 10 days of dioxycycline 2 times daily, advised to take coordinate HBO and Flonase. 8 days into that I still have a croupy cough, temperature below normal, 97.4 and severe chest congestion. Went to my ENT yesterday , no chest x-ray because he said I sound clear, still horribly congested in chest, coughing to the point of pulled stomach and back muscles. Now given 10 days of Levaquin and a medrol dose pack 6 days. In addition, I have asthma issues induced by bronchial infections.
