If you are happy with the amount of pain relief obtained during the trial period, we will carry out the second stage several days later. It also gives time for you to decide whether or not you are happy with the amount of pain relief you are getting. This will allow us to know if the treatment is working or not.

Temporary extension wires will then be connected to the electrode, and these will be brought out through the skin away from your incision. Stimulation will then be undertaken to be sure that the electrode is in a satisfactory position. An electrode that looks like a miniature paddle will then be carefully placed over the back of your spinal cord. A small incision will be made in your back or neck, and a window of bone shaved off the back of your spine to expose the lining over the spinal cord. Local anaesthetic will be injected and you will be lightly sedated. you will be asleep), and your skin cleaned with antiseptic.

What are the alternatives to surgery?Ī number of medications may be useful for pain.

When medications and other treatments are no longer working well or their side effects are to severe, spinal cord stimulation may be of value.

Previous spinal surgery with ongoing leg pain.
