my mother has been diagnosed with UTI couple weeks ago, urine test shows clear, but fever is increasing every day and then urine culture showed ecoli (6-8), she is getting antibiotic injections , finished 6 so far, but fever continuos every day, twice a day, upto 101...so now the doc asked her to stop injections and take proloc and percin....is that ok? what are we missing her? Why is the UTI not getting better? or is it smoething else? she did typhoid and malaria tests and all are negative.
