Hopefully they gave her something other than amoxicillin because that anti-biotic takes a while to work
and get rid of
infections, but it does work. If an infection is not taken care of, with anti-biotics, it can spread, which is why I mentioned the kidneys. Though because she is being treated, it should not be anything to worry about. Make sure she takes all of the anti-biotics and she should be fine. Plus have her drink plenty of water and also cranberry juice.
