Yes. I believe so.
Years back had both wrists sprained and cannot drive properly and cannot even turn the door knob properly to open room doors with both hands.
See the shifu, he had like 'electricity' coming out from his hands and I could feel the electricity pulses down each finger as he grabbed each one by one, with the pinky fingers the most painful.
Then he grab both my injured wrist with a cotton pad filled with sensei oil, and transferred his 'heat' onto my wrist. Super hot until I had to tell him to stop. (both wrist were reddened to the point of scalding but no permanent marks)
That same afternoon, I can drive easier without pain and open the door with one hand. Well worth the $$ then, but now I think the shifu retired liao
