sciatic and 2 herniated discs

My sciatic started in Nov of last year very painful when I moved to the left
And went down my left leg. Tried Celebrex didn't work so in 2013 in Oct.
Went to a doctor who specializes in treatment of sciatic it's a machine that 
Pulls the spine and put fluids back into the discs and heal pain. Machine is
 
The drx 9000. The doctor told me that it takes 20 treatments. By the end of
December will be pain free.
 Well the spine decompression didn't work had a spinal injection in December and
Started second one in June. Hard to live with pain.
