Sore lower back radiates to the leg

The syndrome appears suddenly, and the pain from the lower back radiates to the leg from the opposite side of the patient. This is due to the fact that at the level of the lower back and sacrum are nerve plexus is responsible for innervation of the lower limbs, which in the back of the brain cross and transferred the signal to the opposite side.


For lower back pain and radiating to the leg, the main reason is radicular syndrome radiculopathy. Is expressed in infringement of the nerve root of the spinal cord that conducts sensory and motor impulses from the brain to the muscles. Lower back pain and give the foot pain can be caused by:

  • Osteochondrosis;
  • The inter-vertebral hernia;
  • The displacement of the disk or vertebra;
  • Scoliosis.


Osteochondrosis is the process of proliferation of the cartilage tissue of the vertebrae. This leads to pinching the nerve roots and fibers in paravertebral border, which can cause not only leg pain, but other lesions of the internal organs. In addition to back pain radiating to the leg may feel stiffness in the back, inability to straighten, numbness of the limbs and back. Most will be highly visible, a sharp pain goes into the bottom of the hip. The foot may also be affected by the pain syndrome.

Back pain radiates to the leg1

Treatment for osteoarthritis takes more time and pain can be remove only in the course of glucocorticoid drugs and blockades, as the process is inherently not reversible and requires the conservative constraints of the treatment.

The inter-vertebral hernia

Lower back pain radiating into the left leg may indicate that the inter-spinal hernia or the beginning of the protrusion of the fibrosis ring of the disc. Among the spinal disc is a shock absorber of the human body, which eliminates vibration and maintains flexibility of the spine. It consists of fibrosis of the rings and the pulpous nucleus.

Protrusion called the process of thinning the fibrosis ring which leads to protrusion of the nucleus. Such education can infringe on the nerve and cause pain. Often, when the protrusion back pain and pulls his leg.

Sharp aching pain characteristic of inter-vertebral hernias. The inter-vertebral hernia is a strong degree of protrusion, which is characterized by rupture of the fibrous sheath, and in some cases loss of core. The pain from the spine will spread not only in feet but also in other parts of the body because of the offset of the spine. A special role will play properly assisted, as the condition comparable to a fracture of the spine.

The displacement of the vertebra

When the shift occurs to pinch all the nerve endings in the area. Often back pain and gives the surrounding tissue, the skin is numb, numb feet. Depending on the offset the pain experienced in the right leg or is felt to the left. It depends on the side of the offset and its degree.

Also a symptom can serve as the unnatural pose – man can go, pulling back part of the body or reverse the affected side the side, the back is like "ache". Because of the anatomy of the left foot can be lift up, like a man trying to walk on heels. Dangerous such as not only pain, but also the fact that the lower back is almost completely deprived of its normal blood supply, which can cause necrosis and loss of organ functions for a long time.

The shift occurs after injuries or sprains. The most common for this disease is the winter season because of slippery ice contributes to impact and compression injuries.


Scoliosis is a curvature of the spine from its axis right or left. The disease develops over time and is aggravated by the improper planting or prolonged weight-lifting exercises with pressure on the spine. The vertebrae are formed in a certain shape, with all the complicated muscular apparatus, pulling the vertebrae to the side. Treatment takes a long time and consists in the formation of correct posture muscles that will begin to align pozvonochnye. For this purpose, corsets, physiotherapy, physiotherapy.

Back pain radiates to the leg2


The treatment of the pain syndrome can only be carried out by a specialised technician, as the pain in legs can be a definite symptom for diagnosis. What to do and why hurt is able to say orthopedist or surgeon after the MRI scan, radiography and visual assessment. Treatment is usually carried out in a hospital and start with setting the lidocaine blockade, which relieve pain and are not allowed to develop brain damage. Further treatment is directed at eliminating the root cause that causes back pain.
