upper respiratory tract infection
"I haven't taken an antibiotic for several years because I haven't had a bacterial infection. Over a month ago I came down with a virus but in retrospect it soon evolved into a secondary sinus infection. I respect the avoidance of antibiotics unless symptoms clearly point to bacterial infections, and I was not running a fever, and what my sinus produced did not look foul enough. However, when this didn't abate after close to 5 weeks, even my internist agreed it might be a rare low-grade bacterial infection and gave the green light to try an antibiotic. I started it the day before yesterday and by last night it was the first time in 4 1/2 weeks I got relief from the non-stop post-nasal glob driving me crazy. It couldn't have been more dramatic."
