Nerve Block Injections: What to Expect for Pain Relief

If you’re getting ready for a nerve block injection, or just thinking about one, here’s the big picture: this is a focused, low-risk procedure meant to quiet pain signals from certain nerves. Many patients experience relief quickly, sometimes within minutes. If your doctor adds a steroid, the best results might take a couple of days to work. The main goal? Immediate comfort and lasting relief, so you can get back to your routine and get more out of physical therapy if you need it.

At Surgery Consultants of Florida, we use nerve block injections to help manage both long-term and acute pain, whether it originates in your spine or radiates into your arms and legs. We get it that you might feel a bit uneasy about getting an injection near a nerve. No need to worry, though, since the procedure is smooth, safe, and done right in our office. We’re all about keeping you comfortable and safe.

Here, we’ll walk you through exactly what happens, how it feels, and how long you can expect the relief to stay with you.

Understanding Nerve Block Injections and Pain Relief Nerve Treatment

When we talk about chronic pain, we’re usually looking for a way to cut off the “phone call” your body keeps making to your brain. Nerve block injections do just that by disconnecting those pain messages. These shots usually contain a local anesthetic to numb the painful area right away. We also often include a corticosteroid anti-inflammatory agent to reduce swelling around the nerve. By calming those irritated nerves, we can build a pain-relief plan that actually targets the source of the discomfort, not just its symptoms.

At Surgery Consultants of Florida, we specialize in various forms of Interventional Pain Management. Whether you’re dealing with a pinched nerve in your neck or nagging low back pain, nerve blocks are a cornerstone of our treatment procedures. The shots go straight to the root of the problem, giving results that pills can’t deliver. Plus, you’re not dealing with whole-body side effects. This targeted approach works well for such conditions as sciatica, herniated discs, and complex regional pain syndrome.

A successful pain relief nerve treatment starts with the right diagnosis. Sometimes we use nerve blocks not only for relief, but also to confirm which nerve is causing trouble. If blocking one nerve suddenly eases your pain, we know we’ve found the right spot. That way, our doctors can put together a treatment plan tailored to you. To be sure, knowing what’s causing your pain matters as much as stopping it.

Your Nerve Block Procedure: Do Nerve Block Injections Hurt?

Many people come to us with the same question: Do nerve block injections hurt? It’s totally normal to feel a bit anxious about needles. Nonetheless, we design the entire nerve block procedure to make you feel comfortable. Before the injection, your doctor usually applies a numbing cream or gives you a quick shot of an anesthetic. At most, you might notice some pressure or a quick pinch and sting from the numbing shot. The main nerve block injection, however, usually feels more like an unusual pressure than a sharp pain.

During the procedure, we’ll make sure you’re comfortable on the table, either on your stomach or on your side, depending on the area you’re being treated. To ensure precision, we use imaging tools such as fluoroscopy (a moving X-ray) or ultrasound to guide the needle in real time. That’s how we make sure the medicine hits exactly the right spot. This precision is what makes nerve block injections so effective for cervical spine or lumbar spine issues.

Because of the numbing, most patients tell us the shot hurt far less than they expected. Occasionally, as the medicine reaches the nerve, you might feel a quick flare of your usual pain or some tingling sensation. No need to worry, though, because that’s actually a sign the medicine is working exactly where it should. The procedure is quick, usually done in under half an hour. When it’s over, we’ll put on a small bandage, watch you for a bit, and then you’re free to go home the same day.

Setting Timelines: How Long Do Nerve Block Injections Last?

Another common question we hear is: How long do nerve block injections last? The answer depends on what’s in the shot and your specific situation. If we only use a local anesthetic, relief can last just a few hours or maybe a day. However, with a steroid included, our goal is longer-term relief because it cuts down inflammation. Many patients experience pain relief for weeks, sometimes even months.

The duration depends on factors like how irritated your nerve is, how active you are, and how closely you follow the instructions we give after the procedure. Some patients only need one injection to break the pain cycle and jumpstart healing. Others need a series of nerve block injections to keep the pain at bay. Often, we combine nerve blocks with physical therapy or other treatments, such as Regenerative Injection Therapy, to help get the most out of pain relief.

After your shot, it’s smart to keep a “pain diary” for a few days. Because nerve blocks have a two-phase effect (quick numbing followed by slower steroid action), tracking how you feel helps us fine-tune your care, if it’s needed. If you notice the pain returning sooner than expected, let us know. That info will help us tailor your next treatment. If you’re curious how others have done, feel free to browse our Reviews page.

Managing Side Effects of Nerve Block Treatments and Pain After a Nerve Block

Getting a nerve block injection is usually straightforward and safe, but it’s still smart to know the potential side effects of nerve block treatments. Most people have a smooth experience, but a few mild side effects can pop up. For instance, you might notice some redness, warmth, or a heavy sensation at the injection site. These usually fade within a couple of days. Occasionally, some patients experience a temporary increase in irritation before the steroid takes effect. This is called a “steroid flare.”

It’s also normal to feel a bit of pain after a nerve block as the initial local anesthetic wears off. It’s similar to what you might feel after a flu shot or a blood draw. Most patients manage this easily with an ice pack or mild over-the-counter pain relief (if approved by your doctor). However, if you develop a high fever, severe headache, or sudden loss of bladder or bowel control, call us immediately at (833) 557-7263.

We want your recovery to be seamless. Accordingly, our team will provide you with clear aftercare instructions tailored to your specific treatment area, whether it’s a shoulder, knee, or spine. Take it easy for the rest of the day. Avoid heavy lifting or tough workouts for at least 24 hours to allow the nerve block injections to settle in and start working. Taking these simple steps goes a long way in ensuring your recovery is as smooth as possible.

The Role of Nerve Numbing in Your Recovery Journey

Right after your injection, you’ll probably notice numbness or heaviness in the treated area. That tells you the anesthetic is working. For instance, if we treated your leg, it might feel weak or clumsy for a few hours. Nerve numbing is temporary and totally expected. It’s part of how the treatment works. That numbness helps your body break the cycle of pain by calming your nerves and letting your brain catch a break.

As the numbness fades, the longer-term pain relief takes over. This gives you the chance to engage in your recovery fully. At this time, many patients find they can finally do physical therapy exercises without sharp pain holding them back. Combining targeted pain relief with movement creates the strongest results. That’s exactly our approach to treatment at Surgery Consultants of Florida.

Besides, feeling empowered is part of the healing process. It’s not just about getting rid of pain. It’s about reclaiming your mobility and your life. By using the quiet period provided by the injection, you’re giving your body the space it needs to heal from the inside out.

FAQ: Nerve Block Injections

1. What conditions respond best to nerve block injections?

Nerve blocks can help relieve a wide range of pain conditions, including herniated discs, sciatica, spinal stenosis, and chronic joint pain in the shoulders or knees. They’re also used for complex regional pain syndrome (CRPS) and some types of chronic headaches.

2. How soon can I go back to work after an injection?

Most people can get back to work the next day. If your job is physically demanding or you were sedated, we may recommend a couple of extra days of rest.

3. Are there long-term risks?

Serious risks are rare. There’s a small chance of infection, bleeding, or nerve damage. However, we use advanced imaging, such as fluoroscopy, to safely place the needle at the precise spot in your body. That’s why problems are highly unlikely. Our team is well-trained in these techniques.

4. Can I drive myself home afterward?

We recommend arranging a ride home. The numbness makes some people’s limbs weak or unsteady, and driving right after the treatment may not be safe.

5. How many injections will I need?

That depends on your case and how you respond to the first shot. Some feel better after one; others need a series of shots, spaced over a few weeks.

6. Will my insurance cover the cost?

Most insurance plans, including Medicare, cover nerve block injections when they’re necessary for pain control. It’s always a good idea to double-check with your insurance or call our office to confirm your coverage.

7. What if the nerve block doesn’t work for me?

Even if a nerve block doesn’t give you relief, it provides valuable diagnostic information. It may point us toward a different nerve or another treatment option, such as Regenerative Injection Therapy.
