The Chiro used a TENS unit that took out a lot of fire from my knees. He failed to adjust spine(got bruise on rib cage). Taught me a lot about nutrition and gave balance excersises. Also adjusted neck and released many feel good endorphins but I was later told by my Neuro to not let him do that. I guess she had seen some consequences. Had deep tissue massage that felt good and may have chased the pain around. All in all I am glad I went Good Luck, Ken in Texas.
