Trigger point injections. Sometimes, putting pressure on a certain spot in the back
(called a trigger point) can cause pain at that spot or extending to another
area of the body, such as the hip or leg. To try to relieve pain, a
local anesthetic, either alone or combined with a
corticosteroid, is injected into the area of the
back that triggers pain (trigger point injection).
Facet joint injections. A local anesthetic or corticosteroid is injected into a
facet joint, which is one of the points where one
vertebra connects to another.
Epidural injections. A corticosteroid is injected into the
spinal canal where it bathes the sheath that surrounds the spinal cord and

Local anesthesia is believed to break the
cycle of pain that can cause you to become less physically active. Muscles that
are not being exercised are more easily injured. Then the irritated and injured
muscles can cause more pain and spasm and can disrupt sleep. This pain, spasm,
and fatigue, in turn, can lead to less and less activity.
reduce inflammation. So a corticosteroid injected into the spinal canal can
help relieve pressure on nerves and nerve roots.
Injections may be tried if you
have symptoms of nerve root compression or facet inflammation and you do not
respond to nonsurgical therapy after 6 weeks.

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
If you are pregnant, breastfeeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breastfeeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
