Strong Pulse In Stomach Night A Bump Under My Stomach?

A Bump Under My Stomach? - strong pulse in stomach night

In the middle of the night I woke up with a bladder full enough to go to relieve myself. Now, what has happened recently is that my stomach area starts to hurt. Well, not my stomach, but I think my bladder. Just today, I felt a blow on the left side of my stomach is the size of the palm. He also received a strong boost. When I get out carefully, not just pain, but once a certain pressure. What should I do?
