Does the last one in the lower right corner belong to protrusion and compression of dural sac
According to the picture observation, it may be that the intervertebral discs of the fourth to fifth lumbar vertebrae bulge and compress the adjacent dural sac behind. In this case, there are generally symptoms of lumbar pain or no symptoms. Because there is no compression of nerve roots, there will be no symptoms of pain and numbness in the legs. In most cases, conservative treatment can be taken.
No, there is no obvious oppression. You need to temporarily reduce your activities, pay attention to rest, avoid fatigue and cold, or a posture for too long. For example, you can sit for a long time, stand for a long time, climb mountains and stairs, walk too much, stay in bed, apply blood activating and stasis removing analgesics, go to a regular hospital for rehabilitation training, physiotherapy, acupuncture and moxibustion
Look at the film, you have a prominent waist disc, but it's not serious. You can do a conservative treatment first. Do a lumbar traction treatment once a day for 30 minutes for two weeks. You should avoid sedentary standing and bending activities. You can take oral neurotrophic drugs Mecobalamin tablets and Danlu Tongdu tablets.
