Spines do not go “in and out”, and chiropractors don’t put bones “in”. Otherwise, your doctor would be able to take an x-ray of your spine after the adjustment and show you its fixed. The fact is, adjustments decompress joint pressure, signal nerve receptors to override pain, and change the nerve muscle memory on how muscles contract and relax. The feeling on “going out” is based on the joint pressure, disc or nerve compression that occurs when muscles are pulling harder on one side than another due to the habits of nerve muscle memory. Once nerve muscle memory is changed the spine stabilized and doesn’t feel like it’s “going out”.
