I fell asleep last night and afew hours later I woke and felt pain in my bellybutton only as i sat up. It dosen t hurt all the time but is a little tender to touch. It also seems to be a small swelling to the upper right area. I can walk,stretch,use the bathroom and do other things ok. I have not lifted anything very heavy and rested and took it easy today. I thought I would wait to see how i felt and call my doctor if it gets worse. I do have diverticulosous and IBS. Yesterday my bowls moved three times. I had to strain to help stools come out, but I have strained a lot more in the past with no problems. Is this something I should really worry about?
