i am 39 years old, 5 ft. 3 inches tall, 53 kilos. i undergone thyroidectomy 10 years ago, i have experienced having UTI for past years. Recently i am experienceng frequent urination, brown color foul discharge. What bothers me now is i have blood in urine with blood clots at the beginning of urination and without pain. i feel pain in my right side lower abdomen. i have been urinating blood with grape size blood clots for 3 days now. Can i just ignore this? i carry heavy loads, is there a connection why i am urinating blood?
