@colleenyoung I had read that some infections, especially in older men, aren’t discovered in routine lab cultures, and require more time for the culture to grow. That turned out to be true in my case. I went through weeks of severe pain and difficulties while my urologist said I couldn’t have an infection because lab tests were always negative. Was told it could be the result of years-ago prostate radiation, cystitis, inflammation from BCG, anything but infection. I asked for the longer lab test and it turned out to be actinotignum schaalii. Was given 7 days of amoxicillin but asked for more and didn’t get any. Still have mild symptoms but wish I could grt a longer run of the antibiotics. I felt dramatically better with just two days of amoxicillin but I don’t think 7 days was enough.
