Hello, my girlfriend is ill and went to the doctor 4 days ago and she was told that she has a bladder infection and excess bacteria in her urinary tract or somewhere in that region. She has been on her medicine for the past 2 days that was given to her yet when she started taking them, she contracted a 103 degree fever, her kidneys hurt, she has a great deal of nausea, along with not being able to eat or drink much food or liquids at all. She is worried that something else is wrong because the medicine isn't working very well at all and she is tired of not feeling any better.
