This is a serious question but it sounds strange.?

i was fine earlier but now around my belly button hurts and if i touch the inside of my belly button it is really painful. its not swollen however it does feel a little bit hard it doesnt hurt when im just sitting but if i cough or bend or touch it it hurts alot. any idea what this is?

3 days ago
no piercings and not to much exercise and i am not constipated either lol just to clear thoes 3 things up. i thought about the hernia to but does that happen all of a sudden like this did?

No sorry. Put Ice on it. Or a heating pad. If it still feels like that in a couple days see a doc. You never know how serious things can be. I hope u feel better
