The child came home crying because of a headache ㅠㅠ

My daughter is about to go to her academy, but when I came home, I saw that...

They came in crying, saying they have a headache ㅠㅠ

Can I find out the reason for my headache even when I go to the hospital???

I think I'll feel better if I take one Tylenol, sleep well, and wake up.

They say they can't take the medication.

I don't think I did that when I was young,ㅠㅠ

Even though I'm in upper elementary grades, I have stomach pain and headache.. I'm so sensitive ㅠㅠ
