Yesterday I fell off my bike and slide across the floor. I had 2 jackets on so there was no injury accept a little scratch on my leg. I felt somthing happening on the left side off my belly button. I don't know if it's pain or if somthing is moving. When I lie down then it stops. It feels that there is somthing there and it's moving. There are no marks or bruises on the skin. i have a felling it might be my pelvis or kidney. I was trying to search it up and the pain is called abdominal pain.
