Back pain injections Which injection fits which kind of back pain
Back pain injections are matched to the source of the pain. Trigger point injections treat tight, tender muscle knots. An epidural steroid injection calms an irritated nerve root, the usual cause of sciatica. A medial branch block tests whether the small facet joints are the source, and radiofrequency ablation then gives longer relief. Each is guided by X-ray or ultrasound, takes minutes, and works best as part of a plan with exercise and physical therapy. What the weeks after the procedure look like is covered in radiofrequency ablation recovery.
“Should I get an injection for my back?” depends on one thing above all: where the pain is coming from. A muscle, a nerve and a joint each need a different injection, and the wrong one simply will not help. This guide compares the main options our pain management physicians use, so you know what to ask at your visit. For every back condition we treat, see lower back pain treatment.
Types of back pain injections
Trigger point injections: for muscle knots
When a tight band of muscle is tender and refers pain nearby, a trigger point injection (sometimes called a muscle knot injection) can help. A small amount of local anesthetic, sometimes with a corticosteroid, is injected directly into the knot to release it. It is quick, and most people go back to normal activity the same day. Ultrasound can help guide injections into muscle and soft tissue; the second video shows an ultrasound-guided injection in the lower back. More on trigger point injections.
Epidural steroid injections: for an irritated nerve
When a disc bulge or narrowing of the spine irritates a nerve root, pain shoots into the buttock and leg (sciatica). An epidural places anti-inflammatory steroid next to that nerve. The animation in the first video highlights an irritated nerve beside the lower spine. Epidurals are done under live X-ray, and the third video shows contrast dye being drawn up to confirm where the medicine will spread. See epidural steroid injections, our post on how an epidural treats back pain, and epidural steroid injection recovery.
Medial branch blocks: to test the facet joints
Facet arthritis causes a deep ache beside the spine that is worse with standing and leaning back. A medial branch block briefly numbs the small nerves to those joints. If your usual pain drops for a few hours, the facet joints are likely the source. Our post on facet joint pain explains the test.
Radiofrequency ablation: longer relief for facet pain
After a positive test block, radiofrequency ablation uses a heated probe tip to stop those nerves from carrying pain signals. Relief often lasts many months and can be repeated if the nerves regrow.
How back pain injections are guided
Image guidance lets the physician see the target instead of working by feel. Fluoroscopy (live X-ray) shows bone and, with a little contrast dye, where the medicine will flow, which is why it is used for epidurals and facet procedures. Ultrasound shows muscles and soft tissue without radiation and suits many muscle and joint injections. Your physician explains which guidance your procedure uses before it is scheduled.
How long relief lasts
- Trigger point injection: from days to several weeks; often repeated a few times alongside stretching and strengthening
- Epidural steroid injection: the steroid usually starts working within two to seven days, and relief lasts weeks to several months
- Medial branch block: a few hours, by design, because it is a test
- Radiofrequency ablation: often many months
Results vary from person to person. An injection that brings no relief is still useful information, because it helps rule a source in or out.
Who is a good candidate, and who is not
Injections make most sense when pain has lasted several weeks despite exercise and physical therapy, when the exam points to a specific source, or when pain is blocking you from doing rehab at all. Tell your physician if you take blood thinners, have diabetes, an infection or a fever, a contrast dye allergy, or could be pregnant, because these can change the plan or the timing.
Injections work best as part of a plan
An injection lowers pain; it does not strengthen the back or change how you move. The weeks of lower pain are the time to build strength and endurance with physical therapy, offered at our Brooklyn and Staten Island offices. Our guide to chronic back pain treatment covers the full range of non-surgical options.
When to get help right away
Go to an emergency room or call 911 for back pain with loss of bladder or bowel control, numbness in the groin, sudden leg weakness, or fever.

Questions patients ask
What are the main types of back pain injections?
Trigger point injections for muscle knots, epidural steroid injections for an irritated nerve root, medial branch blocks to test the facet joints, and radiofrequency ablation for longer relief of facet joint pain. The right one depends on the source of the pain.
Do back pain injections hurt?
The skin is numbed first, and most people feel pressure and a brief pinch. Soreness at the injection site for a day or two is common.
How long do back pain injections last?
It depends on the type. Trigger point injections can help for days to weeks, epidurals for weeks to several months, and radiofrequency ablation often for many months. A medial branch block lasts only hours because it is a test.
Are back pain injections done with X-ray or ultrasound?
Epidurals and facet procedures are guided by live X-ray (fluoroscopy), often with a little contrast dye. Ultrasound suits many muscle and joint injections. Your physician explains the guidance used for your procedure.
Can I have back pain injections if I take blood thinners?
Possibly, but some blood thinners need to be paused first, and only with the approval of the doctor who prescribed them. Always tell your physician about every medicine you take before an injection.
