I am suffering regarding urine from yesterday and I am having so much pressure of urine but when I try for that then urine is not coming and I have to force so much for 4-5 mins only then some drops come and I am also getting so much pain in my both kidneys and on abdominal .today I visit for ultrasound but no kidney stone was found. Smell is also coming from urine but earlier there is no such smell from urine. The colour of urine is very light yellow. So please suggest me which medicine I have to take or and reason for the same.
