Had menopause last year. There was sudden bleeding in the urine, coco cola coloured at the end of urine stream. Urine culture tests showed no bacterial infection. USG was done and during test it was a bit painful to the abdomen, and after the test the bleeding increased right after the test and slowly again decreased and then went away after few days after taking homeo medicine Hamemalis. The USG report showed nothing abnormal after that nothing happened for months again from last two days there is a tingling sensation after peeing but no blood, no pain nothing. No history of diabetes. What can be wrong? Please help.
