I often experience stomach pain and indigestion. How can I resolve this?

Noodle dishes, eggs, milk, fried foods, Chinese cuisine, and so on are beyond words.

Since some time ago, I feel uncomfortable and have trouble digesting when I eat this kind of food more often or in larger amounts.

Sometimes I experience severe pain, but usually it's just a feeling of discomfort in my stomach.

When I get a health checkup, I always have an endoscopy, but nothing special comes out, no matter what I eat.

My stomach hurts, and I'm feeling stressed and tired in many ways.

Should I go to the hospital and get a consultation?
