Surgery
Surgery is not often used to treat
chronic pain. The decision to have surgery depends on
your condition and the cause of your pain. Surgery is usually considered only
after other treatments have failed or if it is considered medically necessary.
Surgery may provide pain relief, but it also may permanently
damage your ability to perceive other sensations, such as light touch and
temperature changes. It can also cause a different pain to occur.
Surgery Choices
Surgically implanted pain control devices may be an
option if you have severe chronic pain. These devices deliver drugs or a mild
electrical current to the spinal cord. But they are not effective or
appropriate for everyone. Your doctor may recommend that you try a temporary
device to see if it helps you.
The most common, effective
implanted pain control systems include:
- Intrathecal drug delivery, which
injects a medicine such as morphine or ziconotide (Prialt) into the spinal
fluid through a small, adjustable, implanted pump.
- Spinal cord stimulation, which sends a small electrical current to the spinal
cord from an implanted power source. The electrical current is adjusted with a
controller.
A technique called chemical or surgical sympathectomy prevents the flow of pain signals. In surgical
sympathectomy, the malfunctioning nerve or nerves are cut, usually stopping or
reducing the pain. This procedure, though, may also destroy other sensations
besides pain or create other sensations such as burning or numbness. This
treatment may be used for a type of chronic pain called
reflex sympathetic dystrophy, which is a condition
that affects the
nervous system. This procedure is not commonly done
because it can cause side effects that include new pain and sweating. Your
doctor may want to try a sympathetic
nerve block first, in which
local anesthetic is injected into the nerve to relieve
pain.
Radiofrequency ablation (also called radiofrequency
lesioning) is another procedure that can disrupt the flow of pain signals.
First, you will need to have a test that uses a nerve block, which numbs
specific nerves, to help your doctor locate the nerves that are causing your
pain.
What To Think About
Surgically implanted devices are
not commonly used to treat chronic pain. They may not always control chronic
pain in the long run and can lead to other problems that can complicate chronic
pain or sometimes make it worse.
