Why am i having this belly button pain? - belly button pain more condition_symptoms

Recently, I had this strange pain in my navel, especially when running or walking long distances. I have no idea what it is. What's going on lately, but I refused. Could a hernia or appendicitis? I'm going to see a doctor as soon as all responses are very grateful! Thank you very much:)
