I know that you are right, and that what you describe is a real and growing concern. When I got sick with whatever it was last February(for the first time in years), I was sick for three weeks before going to my doctor. The infection was in my throat, lungs, ears, and eyes. The doctor gave me amoxicillin, which knocked it back a bit, but it came back within a week. I went back, and they gave me Augmentin, which made it go away, or so it appeared. In total, I was sick with whatever it was(they never ran any tests) for over two months. For most of that time, I felt okay except for a really bad caugh that gave me headaches and made it impossible to sleep through the night.
It came back in October, and I went to the doctor, who gave me Augmentin, again. The bug went away, this time for about 6 weeks, before coming back after Christmas. Around New Year’s I went and got a Z-Pak, and it was gone in two days.
I realize that doctors want to use the smallest weapon they can to fight bugs so that the bugs don’t become resistant, but how long can you justify letting your patient remain sick when it’s clear that the treatment isn’t working?
What I found most interesting about this experience is that my PCP made me go through hoops and months of treatment before giving me a Z-Pak, but my wife went to a clinic for the first time and they gave her a Z-Pak first thing.
