About 2 inches to the right (facing me) slightly above belly button, I have a random piercing pain. I've had a cat scan &colonoscopy to determine the source. It feels like scar tissue. Could this be what it is? Is there another device that can detect it & if so, is there treatment? It doesn't prevent me from working out or functioning but when I feel the pain,it can be very uncomfortable.When I rub it it seems to feel better.I am also still fairly numb in ab around belly button. Is this normal?
