Am 68 with spinal stenosis! Have tried shots, drugs and nothing worked! Pain management suggested stimulator implant , 3 days ago I had a trail done! Wires put in next to spine! I have portable programmer on belt ! Works off radio high frequency radio waves! This doesn’t work for everyone! The wires have to be put in exact spot! So far it’s working! Have to wait 2 weeks before permanent controller can be install inside my back!
