psy it was noted i had a bladder infection...and 3 days later i was in hospital for kidney infection,,I was told I just about died...luckily my doctor placed me on anti-biotics and it saved my life..so this time around my urologist said he didnot want to repeat the biopsy and an infection . so i was put on Macrobid 100 mg 4'xs a day for 10days..as soon as I finished  this med..as soon as a day later I began having a reaccurring bladder infection...lower back pain..feeling sick,a burning feeling while urinating,very little urine..hourly urgent need to go..cloudy smelly urine....im 56 obese,hbp,diabetic,lower leg and foot necro...i donot understand why im on and off the macrobid now for the 3'rd time. I think if im on the macrobid for an extensive time it will kill the bacteria... or is there a stronger medicine ? my doctor did a urinalist sensativity test..and im on macrobid..now.....I can also empty the badder and have more control while on macrobid...any ideas ??
