Most lumbar disc herniations can be relieved with conservative treatment and about 80% of patients do not need surgery. If the effect of conservative treatment is not good for 3-6 months and the symptoms are more severe, then surgery is needed. There are very few patients who usually do not have symptoms of herniated disc such as low back and leg pain, but due to exertion or improper posture, suddenly develop severe low back and leg pain, lower limbs can not be straightened, or perineal area numbness, urinary and fecal incontinence, then we should consider acute lumbar herniation of the disc, the vast majority of such patients need surgical treatment, and the numbness of the perineal area, urinary and fecal incontinence, then it is a protruding disc compressed the The cauda equina, or cauda equina syndrome, requires emergency surgery within 24 hours, otherwise the bowel and bladder abnormalities may not be recovered or not fully recovered.
