Case 1: L4/L5,L5/S1 lumbar disc herniation patient has heat from hip to N fossa, every day 2pm – 5pm, rest of the day is normal, when the patient sits down, the heat starts at the hip and then goes down. Case 2: L5/S1 lumbar disc herniation with coldness from knee to lateral calf, mild during the day, heavy at night. Case 3: the patient is 28 years old, after giving birth to a child began to the right half of the body cold, summer cold limbs do not dare to use the fan, not cold limbs normal. Case 4: Cervical spondylosis, unilateral hand cold, never sweat, fingers cold? The other side is normal. A total of 31 pairs of spinal nerves, each pair of spinal nerves connected to a spinal cord segments, each pair of spinal nerves anterior root connected to the anterolateral angle of the spinal cord, posterior root connected to the posterior lateral angle of the age of a few years, each pair of spinal nerves by the anterior and posterior roots of the foramen ovale merged together into the spinal nerves, so, the spinal nerves are mixed nerves, mixed nerves; somatic motor fibers, visceral motor fibers, somatosensory fibers, visceral sensory fibers, the posterior spinal root of the spinal nerves into the peripheral synapses. Spinal nerves are distributed in the skin, skeletal muscles, tendons, joints, the skin’s superficial sensation [pain, temperature sensation, touch], deep sensation [movement, position, vibration] impulses into the center , pain, temperature sensation are superficial sensation. 1, cold, pain and numbness, generally a nerve root compression, local blood circulation due to poor, mostly in the course of long, lingering degenerative diseases, chronic spinal stenosis. 2, heat, pain and numbness, generally seen in acute inflammation of the nerve root, edema, inflammatory stimulation, edema compression caused by acute injury and chronic episodes of intervertebral disc lesions. Acute spinal stenosis, etc. As for treatment each has its own advantages and experience. My practice is; 1 needle knife plus manipulation; 2 needle knife plus drugs
