If you have pain in your stomach when holding urine, it is likely that you are holding urine more than usual, causing pain in your lower abdomen after the bladder swells with urine. It is recommended that you can observe the pain after urination. If the symptoms improve and there is no problem, the pain should be caused by the bladder filling up. If you continue to have pain in the lower abdomen, you should go to the hospital in time to have an ultrasound examination of the genitourinary system, a routine urine examination, and if necessary, a CT and colonoscopy of the lower abdomen to make a clear diagnosis, because there are more causes of abdominal pain, such as urinary stones, colitis, colon tumors, etc., and gynecological diseases may occur. First of all, the diagnosis should be clear before the next step of correct treatment can be carried out. You cannot choose to treat blindly with drugs.
