Chiropractic is the largest, drugless healing profession in the world that specializes in locating and correcting a severe form of spine and nerve stress, a condition that puts pressure on nerves, unbalances your body, lowers your resistance to disease and weakens you: a subluxation. A subluxation is an often painless misalignment of a spinal bone that can affect your nerves, muscles, internal organs, discs, bones, brain function, posture and overall health.
