Diagnosed with bronchitis and incessant coughing one week ago. On zpack and prednisone - 20 mg/2x/day and no relief. Dr. chgd med to Ceftin 500 mg 2x/day on Tues. and continue steroid. Got chest xray last night - neg for pneumonia. Post nasal drip began yesterday and coughing intense. Saw ENT this morning and I have a sinus infection on top of the bronchitis. Changed meds to clindamycin 2xday. Been also using combivent respimate inhaler 3 times per day 2 puffs. Coughing up lots of yellow mucous. What can I do to stop the constant throat tickle and wheezing that I m not already doing?
