Disc Herniation & Radiculopathy
Disc material and inflammation may irritate a cervical, thoracic, or lumbar nerve root, producing radiating pain, tingling, or numbness.
An epidural steroid injection is an outpatient, image-guided procedure that places anti-inflammatory medication near an irritated spinal nerve root.
The clearest role is radicular pain supported by the history, examination, and imaging, not nonspecific back pain alone.
Disc material and inflammation may irritate a cervical, thoracic, or lumbar nerve root, producing radiating pain, tingling, or numbness.
Narrowing may cause arm or leg pain, heaviness, or reduced walking tolerance. Injection may reduce inflammation but cannot widen the canal.
Arthritis and disc-height loss can narrow a nerve exit, sometimes producing a consistent radicular pattern.
Selected patients may be considered after imaging and evaluation exclude instability, infection, major recurrent compression, or another cause.
A clinician looks for a nerve-root pattern and for functional limitations that may improve if inflammation is reduced.
The evaluation confirms a treatable radicular diagnosis and reviews whether injection risk is acceptable.
Your clinician reviews where symptoms begin, whether pain travels, how long it has been present, and how it affects walking, work, sleep and daily activity.
Strength, sensation, reflexes, movement, gait and nerve-tension signs help distinguish joint, disc, nerve, muscle and other potential pain sources.
MRI, CT or X-rays are reviewed when results are likely to clarify anatomy or change the plan. Prior procedure reports may also be important.
Blood thinners, diabetes, allergies, infection risk, pregnancy and other conditions are discussed so benefits and risks can be considered safely.
Cleveland Clinic notes that a lumbar epidural injection takes 15 to 30 minutes in most cases.
Fasting and medication instructions are confirmed, monitoring is applied, and the injection area is cleaned and numbed.
The physician advances a needle toward the intended epidural space while viewing the anatomy in real time.
Contrast verifies epidural spread and helps detect incorrect placement before steroid is injected.
Corticosteroid, often with local anesthetic or saline, is delivered slowly using the lowest effective dose.
You are monitored for weakness, numbness, dizziness or other concerns and receive discharge instructions.
An epidural steroid injection may provide temporary symptom reduction and a rehabilitation window. Some people improve substantially, some partially, and some not at all.
Answer a few quick questions to see which advanced treatment may fit your pain, then talk it through with a specialist at the clinic closest to you.

Derek PA was great. I was nervous to go in and see another pain Dr and have to explain my entire history. He quickly understood me and help me to relax. He is knowledgeable and caring!!
I would refer Dr. Cohen/Dr Wu and the rest of the team at California Pain Consultants to anyone who has had pain running their lives and would like to be treated with respect and understanding. They have lots of options to help with pain.
Both the doctor and his assistant were very calming, answered all my questions and made me feel comfortable. I have only had positive experiences during my various visits. Everyone seems committed to understanding the source of my pain and finding the correct…

Epidural steroid injections usually start working within two to seven days, according to Cleveland Clinic. The local anesthetic may give brief numbness right away, and some people notice more pain for two to three days before the steroid takes effect. Track your arm or leg pain, walking, and sleep so your care team can judge the response.
Relief varies from person to person. Cleveland Clinic reports that relief may last for weeks to months but rarely up to a year, and that approximately half of people experience temporary relief. The injection works best when it opens a window for physical therapy and activity, which may help extend the benefit.
Most people feel pressure and brief discomfort rather than severe pain. The skin is numbed before the needle is placed, and the procedure is performed under imaging guidance. Some soreness at the site or a short-term pain flare can occur afterward. Ask your care team whether light sedation is appropriate for your approach and health history.
Plan to have someone drive you home. Local anesthetic can temporarily affect sensation, strength, or balance in the arms or legs, and sedation affects alertness. Avoid driving or risky activity until sensation and strength are back to normal, and follow the specific discharge instructions your care team provides.
If an injection does not help, that result is useful information. Your pain specialist may reconsider the pain source, review imaging, or try a different approach. Other options may include facet treatment, adhesiolysis, nerve-pain medication, neuromodulation, or referral for a surgical opinion when nerve compression or weakness is significant.
Most plans we work with don’t require a referral to see us. Some HMO plans do. When you book, our team checks your plan’s rules and tells you exactly what’s needed.
