Welcome to The Dudley Group NHS Foundation Trust. This leaflet
will provide you and your relatives with information about caudal
What is a caudal epidural?
This is an injection given into the very base of your spine, close to
your coccyx (tail bone). The Epidural Injection consists of local
anaesthetic (medication to temporarily numb the nerves) and a
steroid (anti-inflammatory medication). Both act towards blocking
the pain signals sent to the brain and the steroid reduces localised
swelling and inflammation which may be putting pressure on the
nerves and causing some of the pain you are experiencing.

This injection is most commonly given to people who have pain
across the lower back and buttocks with some spread into the
hip(s) and leg(s). The local anaesthetic acts on the nerves and
temporarily blocks their function. The steroid decreases
inflammation and improves the chances of longer term pain relief.
The pain relief may take days or weeks to take effect and may not
provide 100% relief.

Risks of the procedure
The injections do not work for everyone, unfortunately this cannot
be predicted.
Side effects of the injection
You may experience some pain around the injection site
Your pain may increase. This is usually short lived and easily
controlled with painkillers
You may have some local bruising and tenderness on your
A feeling of "heaviness in your legs" may occur, this will
resolve after a short period of time
The local anaesthetic can temporarily numb the nerves that
control your blood pressure. The decrease in blood pressure
can make you feel lightheaded and unsteady on your feet.
This is easily remedied by lying down
Headaches - due to the leakage of CSF (cerebrospinal fluid)
Temporary bladder leakage in those with weak pelvic floor
muscles - usually wears off in 2-4 hours
Rare side effects include
Nerve damage
Bleeding and haemorrhage into the epidural space
Side effects of the steroids
There are very few side effects associated with single or occasional
use of steroid injections. These normally resolve within a few days.
Mild side effects include:
Hot flushes, feeling sick , mild abdominal pain
Temporary increase in your sugar levels (diabetics)
Temporary alterations in menstrual cycle (females)
Pre-operative assessment
Please inform us if you are diabetic, have a cough or cold or have
any kind of infection.
The next day you will need someone at home to help you, so you
do as little as possible, but you do not have to stay in bed.
Start simply by taking two walks a day but keep it to a distance you
know you can manage. Avoid overdoing things too soon.
You may have recommended exercises by a physiotherapist
If you can try swimming once or twice a week using front crawl or
backstroke as this is easier on your back. By doing these
suggested exercises, you will allow your back muscles to regain
some of the lost strength and help them support your
If you do not strengthen your back muscles, any benefit from the
epidural will be very short-term, as it is not a cure in itself, only a
form of symptom management.
Expect to have a follow up appointment with the consultant or
crthopaedic practitioner 4 to 6 weeks after your epidural. You may
be referred for physiotherapy if you are already having treatment.
Seek medical advise if you experience any complications at home
such as:
Prolonged numbness and or weakness to lower limbs
Unable to pass urine
Once you have had something to eat and drink you will be
allowed to get up. Prior to discharge you will be assessed for
any numbness and / or weakness in your legs. You will be
asked if you have a headache and checked that you have
passed urine.

you will be allowed to go home
You must not drive home or go home on public transport. Please
arrange for someone to collect you from the day case unit. Please
ensure that you have an adult to stay with you for 24 hours.

about this.
What to do if you become ill before your

assessment unit if you are not well enough to attend for the
procedure. For example any type of infection such as a cough or
cold, or chest infection. Any skin problems such as rashes,
abrasions or cuts to the skin near where the injection will be
inserted may prevent the procedure taking place.
