I have a dull pain under my naval area that only bothers me when I get out of bed ( the motion of my body being from the laying position to the standing position) same thing when I get up from laying position from my sofa. It does not hurt when I am standing, sitting, or anything else, just when I get up from bed. its a dull pain, lasts like a minute or two. I took a CT SCAN, they did not see anything. Blood tests are all normal. No evidence of Hernia. I do have Diverticulitis from time to time but that feels totally different. This has been going on for 2 and a half months so far. Any ideas? I read that if was muscular, the pain would be more on the surface. This pain feels deeper inside .
