Could you please explain why a 9-year-old boy often experiences stomach pain before going to bed?

Patient's question:

Often experience intermittent stomach pain before going to bed at night

Doctor's answer:

Considering the child's indigestion, medication is generally effective. You can try oral pediatric Jianpi Granules and Mamia. Be careful not to let the child eat cold or irritating foods. Instead, focus on easily digestible foods. Additionally, applying heat to the abdomen can also be helpful.
