People in middle age, inevitably have experienced back and leg pain, serious fidgeting, and even can not walk down, the doctor may tell you “kidney deficiency”, through massage, massage treatment, Chinese herbal tonics to strengthen the kidney, some torment after the pain is still the same. In fact, all pain in the human body is related to nerve compression and stimulation, and low back pain is no exception, in order to cure the disease, we must first find the cause, the treatment for the cause to cure the root. It is easy to cause sciatica Sciatica is mostly seen in young and middle-aged people, mostly unilateral pain, pain along the hip has been radiated to the back of the thigh, the back of the lateral calf, the lateral back of the foot, pain is mostly persistent, bending, sitting and standing when the pain increased, lying down slightly reduced, patients often wake up in the middle of the night because of intense back and leg pain, after the acute period patients also accompanied by lower limbs, back of the foot, toes numbness. Sciatica manifests as leg pain, the most common cause may be the herniated disc compressing the lumbar 4-5 or lumbar 5-sacral 1 nerve, the nerve from the spinal cord, which emanates from the intervertebral foramen of the spine at about the lumbar region (tied trouser position), integrates a bundle to form the sciatic nerve and then travels down the back lateral side of the thigh to innervate the sensation of the lower extremities, when trauma causes the lumbar disc to be damaged and herniated and then compress the nerve in the spinal canal, causing lumbar leg Radicular pain. There are many ways to treat sciatica, such as physical therapy and painkillers, which are not a cure. Traditional disc removal for sciatica is effective, but it is traumatic and may cause serious complications if the nerve is not careful. In recent years, neurosurgeons have adopted micro-minimally invasive plus intraoperative electrophysiological monitoring technology, which can accurately remove the herniated lumbar disc and protect the nerves at the same time, and is one of the ideal treatment options. Chronic lower back pain may be caused by sacral cysts Sacral cysts mainly manifest as chronic pain and discomfort in the lower back, sacrococcygeal region and perineum (around the urethral opening, vaginal opening and anus), and may also be accompanied by dorsal thigh pain, sciatica, or even a limp in some patients. Sacral duct cysts are mainly caused by cerebrospinal fluid entering the cysts, resulting in increased pressure of cerebrospinal fluid and compression of surrounding sacral nerves and bones, which can cause bone destruction in severe cases. If the cysts persistently compress the surrounding nerve fibers, severe patients may experience sensory and motor dysfunction and even abnormal urinary and fecal functions. Magnetic resonance imaging can confirm the diagnosis of sacral cysts. For the treatment of sacral canal cyst, surgery is the only effective method to remove the cyst under the microscope and release the cerebrospinal fluid to release the compression of the cyst on the nerve, so as to achieve the treatment purpose, the operation time is short and the trauma to the patient is small, the minimally invasive technique is one of the ideal methods to treat sacral canal cyst.
