In China, back and leg pain is a common disease and a serious problem for patients. Of course, there are many causes of low back pain, but the most common is a herniated lumbar disc. Some patients suffering from lumbar disc herniation will choose conservative treatment, so what are the misconceptions of conservative treatment? 1, the prolapse can be returned to the position except for surgical treatment, conventional therapy, can only make the patient adapt to the state of prolapse, that is, the patient does not feel the back and the affected limb pain, for the cure. Because of the negative pressure in the intervertebral space, the prolapsed fibrous ring and nucleus pulposus can not return at all. 2, lumbar traction lumbar traction can slow down the pressure of the lumbar spine on the intervertebral disc, thereby reducing pain, but the harm outweighs the benefit, it can make the ligaments around the lumbar joints relaxed, day after day ligaments put the regulating joint is not firm, the consequences can be imagined. 3, lumbar spine massage a variety of trigger method lumbar off many subtypes, clinical scoliosis, must use the bending spin trigger method, the appearance of double lower limbs alternating pain, must use double limbs back extension trigger method. The herniated nucleus pulposus is paracentral type, this type has the most incidence, accounting for about 70% of the incidence, using a single limb posterior extension plate, that is, standing on the affected side, trigger the lower limb of the healthy side, fingers press the vertebrae at the lesion and push to the healthy side. If the typology is unclear, it is better not to use the trigger method, so as to avoid the opposite.
