There are several different types of injections. They can be classified as injections for back (and pelvic pain) or for leg pain (sciatica).
Injections for back (and pelvic) pain include facet joint injections, sacroiliac injections and coccyx injections.
Injections for leg pain coming from the nerves in the back are nerve root block injections and caudal epidurals.
What is in the injection?
A mix of local anaesthetic and steroids is injected into the specific area. This aims to reduce swelling, inflammation and pain.
Are there any risks?
There are very small and very infrequent risks of injections. These may include temporary discomfort, an allergic reaction to the medication, infection and bleeding, temporary numbness in legs or injury to the nerves.
