Pain caused by excessive gas buildup in the intestines

After eating, I experience stomach pain and sometimes feel pain in my ribs when sitting for a long time.

When I press my stomach, I hear a gurgling sound, probably because there is a lot of gas in my intestines.

Sit on the toilet and intentionally press down on your stomach. Then, like air escaping from a tube, a fart will come out with a "buu~uk" sound... After some time, it will get better.

I'm wondering if I need to go to the hospital for treatment.
