Epidural injections are a pain management option for patients with leg or arm pain originating from the spine. This is also known as Radicular pain or Radiculopathy. The pain usually radiates away from the irritated nerves. For Example – the pain could be originating from lower spine and may be felt far away in the legs. Pain specialists offer non-surgical options like this one for pain relief. As the techniques used are minimally invasive, and do not involve surgical incision or prolonged recovery, the risks involved are less.
One of the causes nerve pain is the narrowing (stenosis) of the space for these nerves in the spine or narrowing of the space from which these nerves exit the spine. This may be secondary to a slip disc or rupturing of the discs.

Nerve root block /transforaminal epidural, caudal epidural, interlaminar epidural are all epidural injections. Different names are used to indicate the technique used and route of entry. The route or the technique used can have an impact on where the maximum amount of drug is deposited.
Generally a combination of local anaesthetics and steroid are uses in these injections. The resulting pain relief can last for a few months although some people can experience long lasting relief from these injections. Corticosteroids serve dual purpose as an analgesic as well as have anti-inflammatory property. So, they help to control both pain and inflammation.
Immediately after the injection the injection site can feel sore although this is not troublesome for most people. This is mainly because of the mechanical process of inserting needle or at time also due to irritation resulting from the injected medication. But you need not worry about this as it will fade away soon and the pain relief would become apparent as the steroids start to work.
