Hello, what issues you had with urination? Is it burning micturation, or increased frequency of urination?? Chronic infection of urinary tract like cystitis (inflammation of urinary bladder), chronic pyelonephritis (chronic infection of
kidney) could causes pain abdomen, other than this, inflammatory bowel disease, colitis, appendicitis, chronic cholesistitis, gallbladder stones also causes pain abdomen. For urinary issues please consult a urologist, otherwise general surgeon, and a repeat scan of abdomen will help (either ultrasound or MRI or CT).
