Help! Where are SCS probes placed for L5-S1 pain?
The down and dirty: Left Lat. L5-S1 disk blown, had surg., I'm on mucho meds for the last 6 years... New Doc is suggesting SCS.
My question; If they are going to implant an electrode next to my spinal cord, WHERE do they place it to control the pain coming from my L5-S1 injury? Do they implant the electrode right into the L5-S1 space or somewhere further up the spine (L1-L2? T12-T11? or where??).
Essentially, what portion of the spinal cord must be stimulated to relieve pain from L5-S1? I have always assumed that the electrodes would be placed where the pain is originating (L5-S1 area). This would be a problem as I have aracnoiditis and major scar tissue from previous surg. If they place the electrodes into the L5-S1 area, I'm worried that more scar tissue will be produced. If the SCS isn't succesfull, more scar tissue created when they remove the electrodes from the L5-S1 area.
I have been told that the electrodes are inserted well above the L5-S1 area, further up the spinal cord... perhaps at the L1-L2 or T12-T11 area.
Does anyone know where they place the SCS electrodes to "block" pain that originates at the L5-S1 nerve root? If they are going to place the electrodes into the messed up L5-S1 space, I may NOT proceed with the SCS procedure (I don't need more scar tissue!).
Maybe someone else out there has had this procedure to block pain originating in L5-S1 area and could tell me WHERE they implanted the SCS electrodes.
