Where is the origin?!

This is the stupidest thing...I’m actually laughing as I post this...but when I feel cramps, twinges, etc., I can’t tell how deep they’re coming from. I know this makes absolutely NO sense. I can’t tell if they’re coming from the skin/fat on my stomach or if they’re more internal. This whole process has turned me into an idiotic, raving lunatic...and believe it or not, I’m actually a pretty well educated woman. 😂
