Hernia Or Something Else?

The past couple of weeks or so I’ve been experiencing sharp pain in my abdominal region that has gradually been getting worse.
Putting my belt on is particularly painful and couldn’t even do my last set of deadlifts today because of it.
The pain feels like it’s inside my stomach and I have no idea whether this is what a hernia feels like or not. Could it possibly just be something as simple as bad digestion causing this?
