Spinal injections are used in two ways. 
 They can be performed to diagnose the source of back, leg, neck, or arm pain (diagnostic).
 They can be used as a treatment to relieve pain (therapeutic).

When your back or neck problems are severe and have not responded to conservative measures, your doctor may recommend a spinal injection.


Along with spinal injection, exercise program to improve or maintain spinal mobility (stretching exercises) and stability (strengthening exercises) may be recommended by your doctor.
Types Of Spine Injections
The spinal injections are of the following types:
Epidural Injections The epidural injections involve injection of steroidal medications on an affected nerve in the epidural space. If there is an instant pain relief, it
determines the exact pain-causing nerve, and the medication reduces inflammation and results in pain relief.
Selective Nerve Root Block Injections Steroid injection is inserted in the selected nerve root in foraminal area under local anesthesia for diagnostic as well therapeutic use to relieve radicular pain.
Medial branch block injections A median branch block injection is a local anesthetic injection given onto the medial branch nerves; the nerves transmit pain signals from a facet joint. They can help find the exact facet joint spot, which is the pain generator.
Facet Joint Injection Facet joint injections are given directly on the arthritic facet causing pain, where anti-inflammatory and analgesic medicines are given.

Sacroiliac Injection SI joint injections are given to joints located between the ileum (pelvic bones) and sacrum. These injections improve pain in the buttocks, legs,
and lower back.
What Type Of Spine Conditions May Benefit From Spinal Injections?
Spinal injections can be used as therapeutic method in several spinal disorders along with other conservative approaches. Some spine disorders that benefit from spinal treatment are:
 Radicular pain
 Spinal stenosis
 Disk herniation
 Sciatica
 Facet joint pain
 Sacroiliac joint pain
