In sciatica, occasional pain in the lumbar area of the spine may present the first signs of the disease; this can precede acute damage to the intervertebral discs and herniation of its core to the spinal channel with subsequent compression of the ischium nerve, most often in the transition between the lumbar and sacral areas of the spine (L – S1).
In lumbo-sciatic syndrome (lumbago, crick), the disease is caused by ischium nerve plexus compression in the lumbar and sacral area of the spine, with intense acute pain radiating to the lower extremities and resulting in limited mobility.
Often, sciatica develops after exposure to cold and inflammation of the nerve (neuritis ischiadica) or after physical activities in a non-physiological position. Sciatica is most often caused by a sudden movement, lifting something heavy in a non-physiological position, etc.
In sciatica, painful contractions of the deep muscles develop around the spine. In lumbosciatic syndrome, the projection of pain depends on the localisation of the herniation. If the intervertebral disc between vertebra L3-L4 is herniated, pain develops on the front side of the leg; if the disc between vertebra L4-L5 is affected, pain develops on the side of the leg – side projection; if the L5-S1 disc is herniated, pain projects from the vertebra, down the back of the leg, to the heel.
