Hi, dear I have gone through your question. I can understand your concern. You may have small stone in kidney or bladder. It is not necessary that it always leads to blood in urine. Please send me your ultrasound kidney, ureter and bladder(KUB) report. If you have stone then you have to take treatment accordingly. Drink large amount of water and cranberry juice. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
