A spinal cord stimulator is a small device that is placed under your skin to send mild electrical signals to your spinal cord. These signals can reduce the feeling of pain in certain parts of your body. It is used for long-term (chronic) pain that has not improved with other treatments.
Key facts
Spinal cord stimulators are not very common, but they are used more often for people with certain types of chronic pain that haven't responded to other treatments.
It is mostly used in adults who have chronic pain conditions, such as failed back surgery syndrome, complex regional pain syndrome, or nerve pain (neuropathy).
You do not get diagnosed with a spinal cord stimulator. Instead, a specialist (like a pain doctor or surgeon) will evaluate your chronic pain to see if a spinal cord stimulator might be right for you. They will review your medical history, do a physical exam, and may order tests to understand the cause of your pain.
Before the implant, you will have a trial period where a temporary stimulator is placed for a few days to see if it reduces your pain. If the trial is successful, you will have a surgery to place the permanent device under your skin.
A spinal cord stimulator is a treatment option for chronic pain that has not improved with other therapies. It does not remove the pain completely but can make it feel less intense. The device sends small electrical pulses to the spinal cord to block or change pain signals.
Before considering a spinal cord stimulator, doctors usually try other treatments such as physical therapy, pain medicines (like anti-inflammatory drugs or nerve pain medications), nerve blocks, or injections. If these do not provide enough relief, a spinal cord stimulator may be discussed.
Surgery is needed to place the spinal cord stimulator. The procedure is done by a surgeon and involves making a small cut in your back to put the thin wires (leads) near the spinal cord and a small battery pack under the skin, usually in your lower back or buttock area.
With a spinal cord stimulator, you can often reduce your pain and do more of your normal activities. You will have a remote to turn the device on/off and adjust the settings. Some people can feel a mild tingling (called paresthesia) where the pain was. You will need to charge the device battery regularly (if it is rechargeable) or have it replaced every few years.
A balanced diet and regular, gentle exercise (like walking or swimming) can help your overall health and pain management. Your doctor or physiotherapist can advise on safe activities.
Living with chronic pain can be stressful, and a spinal cord stimulator may improve your mood by reducing pain. However, it is normal to feel anxious before or after the procedure. Talking to a counselor or joining a support group may help.
The need for a spinal cord stimulator cannot be prevented because it is used to treat chronic pain that has already developed. However, treating pain early with other methods may reduce the chance of needing a stimulator.
For many people, a spinal cord stimulator can provide significant pain relief and improve function. It is not a cure, but it can make a big difference. Success rates are good when the device is used for the right condition and with proper follow-up care.
