1, lumbar disc herniation why will have difficulty?

When the protrusion of the intervertebral disc is compressed to stimulate the cauda equina, there will be numbness in the perineum and anus. When the central disc is enormous, from the posterior protruding into the spinal canal, the projection plane compression of cauda equina, will appear constipation, defecation can not control, urinary retention, filling urinary incontinence, and impotence, sexual dysfunction, occasionally persistent penile erection. The clinical manifestations of cauda equina syndrome.

At 2, lumbar disc herniation occurs between intermittent claudication?

Intermittent claudication is the main manifestation of lumbar spinal stenosis. But the protrusion of the intervertebral disc will make protruding into the spinal canal, spinal stenosis or lumbar disc herniation associated with spinal stenosis, in addition also showed lumbocrural pain and intermittent claudication, namely to go a long way there will be lower extremity pain and numbness is aggravating, squat or sit down and rest for a while and can walk a long distance.

3, lumbar disc herniation is why the lower limb radiation pain site?

This is caused by the compression of the sciatic nerve or a nerve root of the femoral nerve. Due to disc herniation occurred in the side, so the formation of a unilateral femoral nerve or sciatica. Many in the hip pain, gradually downward radiation, but radiation where a site, to see the outstanding position and. The lumbosacral between the prominent, radiation by thigh and popliteal to toe plantar and leg, the waist; 4~5 prominent, radiation through thigh after, the popliteal to lateral leg ended in dorsal toe; lumbar 3~4 prominent radiation by anterior thigh, leg down in front of the dorsum of the foot in front of. However, lumbar 4~5 prominent, you can have a prominent lumbosacral radiation pain; lumbar 3~4 or waist 2~3 can also have waist 4~5 and lumbosacral symptoms, depending on whether the location is very prominent or slightly outside the center.

4, lumbar disc herniation of the nature of the pain?

The nature of neuropathic pain with numbness and tingling, pain, numbness and pain in the most general. The pain can be aggravated by coughing and sneezing, which is caused by the action of temporarily expanding the spinal canal, increasing the pressure in the spinal canal, and increasing the pressure in the subarachnoid space. Due to the large disc compression standing, bulging is also large, heavy nerve compression. Therefore, walking or standing can also aggravate the pain.

5, how will become lumbago leg pain?

Many patients with lumbar disc herniation after lower limb neuralgia, lumbago can be immediately reduced. This is because the bulging fibrous ring to reduce the pressure near the longitudinal ligament or dural, nerve fiber stimulation is also reduced, and the prominence of the concentrated pressure on the nerve root compression, so change the leg pain. In addition, may also be the nerve root compression leg pain is pain heavier, it conceals the pain, this is because the heavier nerve pain, produce reflex inhibition by cerebral cortex.

6, lumbar and leg pain why weight?

Lumbago and leg pain can be sustained, can also be intermittent. But as long as there is a history of low back pain and radiation to the leg, even if the symptoms disappear at some time, we can not rule out the possibility of recurrence of disc herniation. As long as the oppression and inflammatory stimulation is not lifted, the pain will continue, but may also be light weight. If the patient because of the large amount of work, or waist more prominent bulge increased, increasing the pressure on the nerve root, can aggravate the pain; sometimes rest after local inflammation, and pain will reduce or disappear; sometimes activities occasionally change the nerve root object position and process, namely the protrusion displacement also, can lessen the pain.
