The symptoms of sciatica may be varied, but the most common are loss of sensation or reduction of the reflexes of the affected region; decreased muscle strength; tingling or burning sensation; pain radiating from the lumbar spine to the posterior region of the thigh or leg; increased pain in orthostatism or sitting; and intensification of pain with elevation of the lower limbs.
In general, symptoms may vary, however, in any case they have worsened at night and, generally, sciatica may be associated with low back pain. The symptoms affect men and women, and can intensify with age, because the structures of the spine suffer more wear and compromise the spinal cord and roots that give rise to the nerves.
