No. While the doctor can recommend exercises or stretches, no at-home treatment can replace a trained chiropractor. While you may have a well-meaning strong friend, who offers to pick you up and “crack” your back, spinal adjustment is a delicate process, and dangerous in the hands of amateurs.
An adjustment is a carefully measured force, applied in to a targeted joint in a very specific way. It is unsafe and virtually impossible for a layman to correctly and accurately provide the same services you would receive from a licensed chiropractor. Although amateurs can produce the same “popping” sound of a joint releasing gas, this kind of manipulation is often counterproductive, and can make a misaligned spine even more unstable.
