Why do some practitioners experience back pain?

The reason for this is in most cases, that the spine is not naturally positioned, straight and relaxed. Thus the flow of Qi and blood is blocked especially in the lumber spine area, which causes pain.

Another possibility is that there is a spinal column injury or that there has been one in the past. The energy (Qi) now dissolves the blockade, which was caused by the injury; this is why temporary pain occurs.

Back pain may also occur if the energy of the practitioners kidneys is too week. In any case one should continue to practise. As healing progresses and Qi is being accumulated the pain will ease gradually and finally disappear.
