Spinal cord stimulation for chronic pain

Hi

I have had Parkinson's for 11 years but after an op 5 years ago I have CRPS in my foot

I have had 2 discs operations but sciatica is still a problem

Because of my chronic pain  I have been offered Spinal cord stimulation - Neurostimulation but am keen to find someone who has had this procedure who also has Parkinsons

any advice?  Meg
