Or big joints?

You can try to massage the other hand with your hand every day.

Do it for a long time

With one hand.

Extending from the root of the other hand to the fingertips.

Don't push.

Just gently use your thumb and forefinger ~ ~

You try.

Doing it when you have nothing to do has some effect.

And don't break your joints ~! Do you understand? That will thicken the joints on your fingers! !

I don't surf the Internet. Have you ever written it?

but

That's what I'm willing to do ~ ~ wrench my finger when I have time ~!

It feels a little effective!
