The cause of lumbar disc herniation is the rupture of the fibrous ring of lumbar disc, and the protrusion of nucleus pulposus stimulates or compresses nerve roots and cauda equina, which is one of the common causes of low back and leg pain. In lumbar disc herniation, the incidence of lumbar 4 ~ 5 and lumbar 5 ~ sacrum 1 is relatively high, accounting for about 90% ~ 96%, of which only 5% ~ 22% suffer from multiple intervertebral spaces at the same time. Sometimes patients with lumbar disc herniation will have lower limb pain when they are serious, which will affect their walking and other symptoms. In severe cases, it will also cause abnormal urination or incontinence, which will greatly affect the quality of life of patients.
The symptoms of lumbar disc herniation are back pain and soreness. Radiation pain of lower limbs, due to lumbar disc herniation, mostly occurs in the lumbar 4-5 or 5 sacral space, that is, the sciatic nerve root. Therefore, most people with lumbar disc herniation have sciatic nerve pain or start from the buttocks and gradually radiate to the posterolateral thigh, lateral calf, instep, lateral sole and toe. Central protrusion often causes bilateral sciatic nerve pain.
The symptoms of lumbar disc herniation are paresthesia and numbness. Lumbar disc herniation causes local compression or involved compression in the nerve root contact area, which is due to the compression and deformation of the fibers and blood vessels of the nerve root body, resulting in ischemia and hypoxia, causing pain and numbness in the legs, and also causing chills in the lower limbs and weakening of the dorsal artery of the foot.
There is also a kind of hyperthermia commonly used in physical therapy of lumbar disc herniation, such as hot compress of traditional Chinese medicine and collapse of traditional Chinese medicine, which can promote local blood circulation and improve the condition. However, after the symptoms of lumbar disc herniation appear, it is recommended to rest first, and the effect of physical therapy combined with rest will be better. If the patient does not rest for treatment, the symptoms may not be obviously relieved, or the effect may not be good. Therefore, for patients with lumbar disc herniation, it is generally recommended that patients try to avoid factors that induce disease recurrence or aggravate symptoms while treating or paying attention to daily. These factors mainly refer to sitting for a long time, bending over to carry heavy loads and catching cold. Good living and working habits should be maintained at the same time of treatment in order to have good results.
