I have back problems from surgeries my body scared from them to the point that the doctor said that nerves and the scar could not be separated that is what happened to me but if you have Constant pain then the pump or the spinal cord stimulator might help I tried The stimulator but it didn’t work for me but it’s worth a try I know people who have them only one thing if you have a pacemaker you can’t have one but you could have the pump
