Patients who have severve
back pain and who have a damaged nerve - with weak muscles and numb
areas of skin - may benefit if an anaesthetic injection is given into
the epidural space in the spine. This type of injection seems particularly
useful for patients who have prolapsed discs producing nerve pain
that has not responded to any other sort of treatment.
This injection is given into the space between the bony outer walls
of the spinal canal and the membrane which covers the spinal cord,
and in addition to containing an anaesthetic the injection usually
contains a steriod. The anaesthetic numbs the spinal cord and the
steroid helps to reduce the amount of local inflammation which has
been caused by the prolapsed disc.
The pain relief produced by an epidural injection may be temporary
or permanent, and about half of all patients get at least some relief.
The procedure is fairly uncomfortable but the relief can be tremendous.
