Performed under X-ray guidance, spinal injections can be used for diagnosis of pain source or treatment for pain relief.
For pain relief, spinal injections can be more effective than an oral medication in delivering medication directly to the source or location of the pain. The duration of back pain relief provided depends on the type of spinal injection. The most common epidural steroid injection is used in temporarily relieving lower back pain especially for people who experience episodic severe back pain.
For diagnosis of pain, spinal injections (together with physical and other imaging examinations) can help in developing further treatment for the patient.
