Acupuncture, Chiropractic, and deep tissue, need I say more?
In Busan there is a wonderful man, named Dr. You. He is trained as an oriental medical doctor as well as a chiropractor. If you ever are having issues and want to try eastern medicine this is your guy.
He has gotten one of this medical degrees from Australia, so his knowledge of English is superb. He is also on the stronger side of things, so adjusting Western bodies is easier than say some shorter (smaller) Korean Doctors.
