I have been diagnosed w/ acute bronchitis, although the symptoms were rapid onset of severe sore throat, difficulty swallowing, fever, chills, aches, etc., that came on 4 days after returning from Latin America. My spouse is scheduled for hip replacement surgery in 3 days, and I have not had any abatement of symptoms, which now include severe and constant cough, green mucus, and fever (100-101). I went to our clinic, and requested a strep check but was not given one (I forgot to request  during the actual visit). I would like to now request azythromycin to protect against secondary infection, because at the rate I am going, it wouldnt be appropriate for me to be AT the hospital, much less assist with his care. Is this reasonable?
Yes you need to take care of your upper respiratory tract infection/bronchitis. For this a course of antibiotics like augmenting or azithromycin along with symptomatic treatment may be required. Consult your local physician and get the prescription.
