A herniated lumbar disc can compress the nerve roots afterwards, triggering pain in the buttocks and pain in the lower limbs. At this time, if you want to make the pain relief fast, you must strictly lie flat on a hard bed, not to get up and not to get down, in order to reduce the pressure of gravity on the lumbar disc and slow down the protrusion of the lumbar disc. The purpose of computer traction is to make use of the negative pressure attraction and the elasticity of the ligaments to make the protruding lumbar discs return, and if the effect is ideal, it will work quickly, so that the lumbar discs no longer compress the nerve roots, and naturally, the pain in the buttocks and lower limbs will be relieved immediately. In addition, it is also necessary to cooperate with drugs such as mannitol to make the nerve root edema dehydrate quickly, and the pain will be significantly relieved after the swelling is eliminated.
