Your pain seems to be that of stones in the ureters (the pipes that drain urine from the kidneys). The pain that you have described is typical of ureteric stones. In order to confirm this you need to get an ultrasound
abdomen and x-ray KUB (kidney ureter bladder). Get these done fasting in the morning. In the evening before take 2 Dulcolax
tablets and 4 activated charcoal
tablets so your bowels are empty. Your problem does not seem to be related to bowel. Treatment of the stones if they are found will depend upon a number of factors including site size.
