pain
"I had spinal fusion in lower lumbar region 9 years ago.  I was fine until August '08.  I had such severe sciatic pain doctor progressively put me on Ultram ER 200mg 1x / day.  It worked great.  Pain went away after 4 months.  I stopped taking Ultram and now I am dealing with withdrawal symptoms.  PAY ATTENTION to warnings about long term usage."
