urinary tract infection
"I was born with 4 kidneys, and it seems some of the other reviewers "side effects" were actually kidney/bladder infection symptoms. These infections spread fast, and can be lethal. Amoxacillin is a gentle savior for me, I still have 3 of 4 kidneys, after surgery and countless urinary tract infections, I trust it very much. It can take as little as 2 days to go from UTI to bladder, and a day or so more to kidneys, nip it in the bud, at first stinging. Because if you start to feel constipated,  it's probably not, that is a kidney infection symptom. These infections scare the daylights out of me, it has been quite a while since I was hospitalized, amoxacillin is safe and much easier on the body than cipro."
