I had a spinal stimulator implanted this year. It took the trial and two surgeries to implant. The process is very painful. Its been a little over 2 months since my last operation. The stimulator is not what I thought it would be. For me the trial procedure was so painful I never really could tell if it would really help or not but had the stimulator implanted anyway. It helps sometimes I think but my pain is random and can go from bad to severe very quickly and for no apparent reasons.
Think twice about putting yourself at risk for more pain because for me that's what happened. I have more pain no from complications and slow healing from the surgeries.
