Lower abdominal pain when passing gas?

Lower abdominal pain when passing gas?

I would like to discuss symptoms of lower abdominal pain and bloating.

A few days ago, I started experiencing persistent lower abdominal pain and gas.
At first, I thought it was just a mild pain and didn't take it seriously, but
As time passes, the lower abdominal pain and gas are gradually getting worse.

It seems to get worse, especially after meals or when unable to pass gas.

First, I tried to improve my eating habits.
Consume a lot of high-fiber foods and water.
I have chosen foods that help with digestion.

Secondly, I started exercising regularly.
Walking or light stretching helps relieve lower abdominal pain and gas.
I started exercising a little each day because I heard it would help.

However, the symptoms of pain and bloating still persist.
I'm worried because it hasn't been fully resolved. 

So, I would like to ask for your help.
Anyone who has had similar experiences or effective solutions?
If anyone has knowledge about this, please offer your advice.
