Pain messages travel over nerve pathways to the spinal cord, inside the spine. The spinal cord carries the messages to the brain. Constant pain messages can cause long-term pain that is hard to treat. This is known as chronic pain. Spinal cord stimulation uses a medical device to send signals to the nerve pathways inside your spinal cord. These signals help block the pain.
Your healthcare provider does a stimulator placement in two stages. He or she does a test (trial) stage to see how well spinal cord stimulation works for you. If the trial stage is a success, the permanent stimulator system is put into place.
Your doctor will give you guidelines on how to get ready for the procedures. Tell your doctor what medicines you take, and ask if you should stop taking any of them. Do not eat or drink for 8 hours before you check in for the procedures. Certain criteria must be met to be a good candidate for the spinal cord stimulation device.
Your doctor will place the trial leads under the skin on your back through a small incision. He or she will place one end of the leads near your spinal cord. Your doctor will attach the other end of the leads to the stimulator power source. He or she will then adjust the stimulator to the right level. For the trial stage, you wear the power source outside your body.
Your doctor will instruct you to keep a second pain log during the trial stage. You can compare this log with your first pain log to show how well the stimulator system is working for you.
If the trial stimulator works well for you, a permanent system might be indicated. This must be done in the hospital. Prepare for it as instructed. The receiver or the power source is implanted under the skin on your abdomen or buttocks. The power source is small, so it won’t show under your clothing. Some devices are rechargeable After the system is in place, the settings are checked to make sure they are at the right level for you. If necessary, the spinal cord stimulation device can be removed at any time. Not all these systems are MRI compatible. Find out from your doctor if you still can have an MRI once the system is installed.
You may stay in the hospital overnight. The implant site will be sore for a few days. The leads need some time to become fixed so they don’t move around. Your doctor will tell you what activities to avoid for the next month or so.
Call your doctor right away if you:
Have fever over 100.4°F (38°C)
Have pain, drainage, or increased redness at the implant site
If you don't feel the stimulation anymore
Also call your doctor if the pain symptoms return.
