cupping therapy

I think I had a cupping machine at home when I was young.

Mom, who had a tiring day, is resting her shoulders on that machine.

I remember the black blood pooling when I put it on my back.

Do traditional Korean medicine clinics also perform cupping therapy?

So, is it definitely refreshing and good?

Can I do it frequently?

If it's good for my body, I want to go and try it.
