Benefits and Risks – Neurostimulators

Neurostimulation may reduce your chronic pain and improve your ability to go about your daily activities. Talk to your doctor about the benefits and risks associated with using a neurostimulator for your complex regional pain syndrome symptoms.

Benefits

Typically, people who have success with neurostimulation:

  • Experience at least 50% reduction in their pain1-6
  • Feel a mild tingling sensation in the area where they feel pain
  • Decrease the need for oral medications1-6
  • Reduce side effects of oral medications1-6

In addition, this treatment:

  • Does not involve permanent changes to the spinal cord or nerves
  • Can be adjusted to provide different levels of stimulation for various activities and times of day
  • Is reversible – your doctor can turn it off or remove the system
  • You can try the therapy for a short period of time before you receive a permanent implant

Risks

Although the goal of neurostimulation is to manage pain while causing as few side effects as possible, all pain treatments have risks.

Common side effects include:

  • No stimulation resulting in a loss of pain relief due to lead movement or other causes
  • Intermittent stimulation
  • Stimulation in the wrong location if leads move
  • Uncomfortable stimulation
  • Pain at the stimulator site
  • Programmer or data transmission problems

Serious adverse effects occur less frequently, but are possible:

  • Neurostimulation does require surgery – as with any surgery, the risk of infection exists
  • Blood (haematoma) or fluid (seroma) may leak into the area where the neurostimulator is implanted
  • In rare cases, spinal cord injury may occur from incorrect surgical placement of the extension
  • Device complications may require additional surgery to relocate, repair, or replace parts of the system
