I am 33 year old male. I just recently noticed a squishy ball in my belly button toward the top of the button. It does not hurt real bad but is very uncomfortable. The ball squishes in and out and I feel a squishy feeling going in and out of my stomache. The ball is about the size of a nickle. Half of the ball is in the belly button, the other half is above the belly button. The ball is not protruded outward just a little from the top. The pain I feel is like if I were to stick my finger in my belly button and keep on playing with it.. That tickly anoying feeling. I do exercise now and then. I thought it may be ahernia but there does not seem to be major pain. I am thinking it may be a tumor or cancer or something...Can this simply be my belly button???
