I Went To Urgent Care Type Facility On Dec. 19

I went to urgent care type facility on Dec. 19 for a sinus infection, they gave me antibiotics. Then I got a terrible cough and went back Dec. 26. They gave me Perle Tuss...helped with a more productive cough...but still continued to cough badly until my side and abs were so sore. Then I started to get swollen glands and sore throat along with cough and went back a week ago this Friday. They diagnosed me with bronchitis. Gave me a shot of rocefrin and a steroid shot, another Perle Tuss and a stronger cough medicine. It helped a lot. Still have a cough..not as bad. But today I've started my symptoms all over again. I've scheduled an appointment with my regular doctor which is out of town. I've never had this stuff where I couldn't get rid of it. This has been going on since dec. 19th. I cannot take the predizone pack because I have a bad reaction to it and it takes me a week to get over it. What do you think the problem might be?
