For most of these cases, the areas where pain and numbness are felt do not coincide with the areas that the compressed nerves control. This is an indicator that there are other causes. When studied further, it is often the case that one of the joints along the area from the pelvic region to the vertebral region is experiencing joint dysfunction; once treatment is given with this in mind, the pain and numbness disappears.
Symptoms of this joint dysfunction are not limited to back pain, stiff shoulders, and joint pain; it could also cause headaches, menstrual pain, as well as symptoms with seemingly unknown causes, such as numbness in the hands and feet, dizziness, and bleariness of the eyes. Additionally, for cases in which joint dysfunction occurs in the joints of the pelvic area, if left untreated, this could lead to degeneration of the intervertebral discs, such as a herniated disc or spinal canal stenosis.
Moreover, if it occurs in the shoulder or back, in addition to pain and stiffness in the neck and shoulders, the situation could lead to tenosynovitis, or even expand to the arms to cause medial epicondylitis. From my clinical experience, there have been many cases in which the patient was diagnosed at the hospital as having CRPS, but recovered, or saw great improvements, through treatment of joint dysfunction. The same thing could be said for pain, numbness, and abnormal sensations (burning sensation, coldness) diagnosed as “neuropathic pain,” which is a term that is heard increasingly often these days. For such pain, it is conceivable that the cause of the pain was in the joints and not the nerves, or that the joint-based pain lasted for so long that it shifted to nerve-based pain.
