I Have Been Sick On And Off For A Month

I have been sick on and off for a month . My cough has not subsided at all. First diagnosed with Bronchitis was on antibiotic.- z pack for 5 days. Then this week was diagnosed with Influenza B. taking TamiFlu- on last day. My throat feels like I have a pill stuck in it and I am still very tired. I cough more when I talk. I feel like they are missing something, because I dont feel any better. Any suggestions if I should get a chest xray or other tests?
