What are the effects of Chuna therapy?

When I had elbow pain before, I received acupuncture treatment at a Korean medicine clinic.

I also received two sessions of a treatment called Chuna therapy.

However, the doctor uses electricity to manually treat the painful area.

And touching various parts of my body, I feel a tingling electric shock.

I heard that. But I'm not sure. I wonder if this Chuna therapy is really effective.

What contribution did you make to the treatment of elbow pain?

Of course, my elbow healed over a long period with acupuncture and cupping.

I don't really know much about Chuna therapy.

Did Chuna therapy have an impact on the treatment?
