Nice.
I work with people damaged from taking Fluoroquinolones (like Cipro, ciprofloxacin, Levaquin, levofloxacin, avelox, norfloxacin, etc).
These are powerful antibiotics. With severe potential side effects (like waking up in the hospital the next morning and your achilles tendon literally falls apart and ruptures).
I wish doctors would test more as you just described.
Much of prostate infection is fungal and not bacterial. Yet doctors prescribe Cipro as a matter of course without ever testing to identify the type of infection.
Pneumonia can be viral. So giving antibiotics for it without testing is pretty stupid, especially antibiotics with such sever potential side effects). Doctors don't test for the type of bacteria.
Hell, they give Levaquin for acne. Crazy stuff.
If doctors claim to follow science based medicine (ha!) then they should apply some actual science to their prescriptive process (like accurately diagnosing the cause).
