Usually,
sciatica only affects one side of the lower body and the pain often radiates from the lower back all the way through the back of the thigh and down through the leg.
Some combination of the following symptoms is most common:
Lower
back pain, if experienced at all, is not as severe as leg pain
Constant pain in only one side of the buttock or leg, but rarely both the right and left sides
Pain that originates in the low back or buttock and continues along the path of the
sciatic nerve - down the back of the thigh and into the lower leg and foot
Pain that feels better when patients lie down or are walking, but worsens when standing or sitting
Pain that is typically described as sharp or searing, rather than dull
Some experience a "pins-and-needles" sensation,
numbness or weakness, or a prickling sensation down the leg
