[Concern] My elementary school child keeps complaining about ankle pain~

As the older child started to gain weight

They keep saying that the inside and outside of their ankle hurt.

I'm currently in the 4th grade of elementary school, and I'm a bit on the chubby side, you know ㅠ

It's not like I sprained or hurt myself or anything.

They say they don't want to see the hospital doctor again.

Standing posture is also not good.

So..

I'm 고민중이에요ㅠ Should I forcibly take him to orthopedics? I think he should receive manual therapy or posture correction.
