Sciatica   is   a   common   type   of   pain   affecting   the   sciatic   nerve,   a large   nerve   extending   from   the   lower   back   down   the   back   of each leg. Sciatica    is    caused    by    irritation    of    the    root(s)    of    the    lower lumbar and lumbosacral spine. Common symptoms of sciatica include: • Pain in the buttock or leg that is worse when sitting • Burning or tingling down the leg • Weakness,    numbness,    or    difficulty    moving    the    leg    or foot • A constant pain on one side of the buttock • A shooting pain that makes it difficult to stand up Sciatica   usually   affects   only   one   side   of   the   lower   body.   Often, the   pain   extends   from   the   lower   back   all   the   way   through   the back   of   the   thigh   and   down   through   the   leg.   Depending   on where   the   sciatic   nerve   is   affected,   the   pain   may   also   extend to the foot or toes. For   some   people,   the   pain   from   sciatica   can   be   severe   and debilitating.    For    others,    the    pain    from    sciatica    might    be infrequent and irritating, but has the potential to get worse. Seek    immediate    medical    attention    with    any    symptoms    of progressive   lower   extremity   weakness   and/or   loss   of   bladder or bowel control.
