Why does pain move?
But anyway, let us get back to the topic at hand and try to clarify why pain moves. Pain is basically controlled by the nervous system, so imagine something happens to your back, ¨nociceptors¨will send this information to your spine and from there to the brain. Now, let us suppose this ¨injury¨ keeps bothering you for a while, and these ¨nociceptors¨ will be firing away 24/7 during this whole time. At the end, the pain becomes centralized. Now, this is where it gets interesting. Your spine is also receiving at the same time information from all the different parts of the body. Once the original pain has become ¨centralized¨, the spine can sometimes make an error and get confused with all the different types of information that it is receiving from its nerves (6). This confusion can lead to the pain moving from one place to another. Now, when this happens it doesn´t mean that you have injured yourself in a new area, it just means that your central nervous system has made an error in its processing of the information.
