Cracking your own back, or self manipulation of the spine, that is repeatedly performed may result in a hypermobility of the spinal joints. This means that the joints are less stable and move excessively, which may perpetuate pain and instability in the spine. If you spine feels like it is tense and needs to be popped or cracked, seek out a chiropractic physician or osteopathic physician who specializes in manipulation of the spine in order to have your back adjusted correctly.
