kidney infections
"Took Cipro for a month and it cleared up a very major kidney cyst infection for me.  I was extremely unwell and in hospital.  I am 50 and a regular walker.  I found all symptoms minor and manageable until week 4 when I did develop some extra aches and pains, and felt a general malaise and unwellness.  I even felt a bit depressed on the last day of taking it.  Stopped Cipro yesterday and have woken up feeling like my old self.  I would take it again though because it was so effective at clearing up my infection."
