Hello there , I need your guys help & advices, some of you might have gone through this thing. I went to see Dr last month and was diagnosed with UTI. He prescribed me "macrobid " to kill all Infectious , I did took it , it really helps. I went through see dr again ok December 27 ,2016, I've told him all of my symptoms like burning after pee and feeling pain or tingling , when eat spicy foods it burns so bad, he did urine test n told me everything is normal n it seems like infection is gone. But if I get infections gone, why do I seee this white debris , flakes stuff floating in urine? I get little cramp too , I'm taking ciprofloxcisn which he prescribed me, but it seems like it doesnt help at all and "Macrobid" is much better for me. is this serious??? I'm soo scared, I have to get my blood test done on Monday. Will he be able to tell if there's something wrong with me in blood test ? Please give some helps .
