Thank you for your query.
With regards to your abdominal pain
and discomfort it seem to be related with IBS ( irritable bowel syndrome
So I would recommend changing your lifestyle like:
-Avoid spicy food, smoking
-Eat healthy food reach in fibers.
-Drink plenty of water.
-Increase your physical activity.
-Use probiotics and simethicone
If it's not enough consult your gastroenterologist.
Wishing you health.
