Internal pain: Localization of pain inside our bodies is difficult because nerves follow a map from early in evolution. So the ureter that connects the kidney to the bladder is not where it used to be. When stretched at the top we feel it high in the back where it attaches to the kidney. As something moves down we feel it wrap around to the front and down to our groin. Urethral pain is from the procedure itself
