Knee Markings

So I now have these four burn marks on my knee from my treatment that I've been getting.  The last time I was there the lady and I were talking and she typed whatever the Korean word was for the treatment into her translator on her phone and she said that there wasn't an English translation.  That's when you know you're getting close to the heart of holistic Asian medicine.  I was watching her set it up and it almost looks like dryer lint that she rolls between her fingers into a wick before attaching it to my knee.
