Good morning. I have lower abdominal pain as if it happens after charging or after exercise, like a press pain, kind of that. It's mainly painful at night, even though I lie down. I thought maybe from the fact that I need to rest, to lie down. Has anyone had this? Please share your experiences. I also feel slight movement (light as a fish or light taps) in the same area where it hurts. Or is it because I sit too much (at work)?
