No, its impossible to adjust yourself. It is possible to make your spine pop and feel better, but its not possible to find the misalignment thats causing the problem and specifically move it. If you rely on adjusting yourself or having someone who is not a chiropractor adjust you, the parts of your spine that pop will become too loose and unstable, while the real problem, the locked misalignment, will become stuck and decay. Chiropractors would never attempt to adjust themselves. They go to another chiropractor to receive their adjustments.
