The pain can be due to acute sprain, strain, pain because of nucleus pulposus compression nerve, compression of spinal cord stimulation nerve, but also because of chemical substances, acute sprain after the production of inflammatory substances to stimulate the nerve, but also because of unstable posture, strain and other causes of pain, which is the cause of chronic pain . Pain can be relieved by bed rest, relieving posture and muscle tension, and after the elimination of inflammatory substances, but numbness is after pain, showing that the nerve is indeed compressed, and for a longer period of time, and the degeneration of the nerve will occur after the compression is more difficult to recover, so it is a more serious case of numbness than pain shows, and attention should also be paid to check whether there are other diseases caused by ischemia, etc., resulting in numbness.
