A person is holding their knee in pain.

What You Should Know About Nerve Block for Knee Pain

Knee pain severity comes from a variety of factors and can vary from person to person. Anyone can experience the impact this pain has on fitness, work, and lifestyle. A nerve block is a process that prevents pain signals from reaching the knee. Let's take a closer look at genicular nerve block and how it helps manage knee pain.


Knee Pain

Your knee is a major weight-bearing joint. It can undergo tremendous wear and tear throughout your life, and an injury can result in lifelong pain. Age, lifestyle changes, weight loss, and gain, and stiffness can all contribute to knee pain.

 

Almost a million knee replacement surgeries took place in the United States in 2017.

 

Here are some of the more common conditions that create severe knee pain:

 

●     Knee ligament injuries

●     Meniscus tears

●     Knee arthritis

●     Chronic knee pain

●     Rheumatoid knee arthritis

●     Post-traumatic arthritis

●     Knee osteoarthritis

 

Nerve blocking is also an option for patients experiencing pain after knee surgery as well as chronic knee pain sufferers who aren't candidates for surgery.


Genicular Nerve Block

A genicular nerve block stops nerve signals to the knee temporarily. It's a relatively new procedure for knee pain that's not responsive to conventional treatment.

 

Doctors will carefully diagnose your condition. They'll gauge knee flexibility, pain level, joint function, past conditions or injuries, activity, and family history. The clinician will use physical evaluation and X-rays. To get a handle on specifics related to knee pain, they may conduct any of the following tests.


Bloodwork

Bloodwork checks for anti-CCP antibodies, an indicator of rheumatoid arthritis.


Fluid Tests

Doctors may draw knee joint fluid. If there are signs of uric acid crystals, that could be inflammation and gout. The tests may reveal bacteria as a symptom of infection.


Imaging

Besides X-rays, there may be MRI or CAT scans to get detailed images of soft tissue and bones. The process will also explore unexplained swelling or diagnose the injury.


The Nerve Block Process

There are different nerve block treatments. Doctors base approach to treatment on the pain's location. Besides the knee, doctors apply nerve blocking to the arms, backs, buttocks, legs, face, and neck.

 

The nerve block process consists of a local anesthetic injection. It's targeted to a nerve or group of nerves to lessen your pain. Depending on the condition, the local anesthetic may come with anti-inflammatory medication. It's applied to encourage healing damaged nerves.

 

The procedure is usually done on an outpatient basis. You lie on your side or stomach. Most likely on an ultrasound or X-ray table. This gives your doctor easier access to injection points.

 

If you appear anxious, the doctor may offer a mild IV sedative. Your doctor will prepare this beforehand so that you can set up a ride home post-procedure. You'll also need to fast before the process for at least six to eight hours.

 

After they've numbed the area with a local anesthetic, the doctor will give the injection. Using video images provided by the fluoroscopy or ultrasound, the doctor can guide the injection to the precise spot. Generally, patients express only mild and momentary discomfort. Afterward, you'll be able to rest.


Potential Side Effects and Risks

Like any medical procedure, we need to consider the potential risks and side effects of nerve block treatment. They include:

 

●     Soreness or bleeding at the injection site

●     Unexpected bleeding

●     Worsening pain

●     Infection

●     Drug allergy

●     Nerve damage

 

Depending on the type of nerve block treatment, you may experience any of the following:

 

●     Trouble swallowing

●     Hoarseness

●     Red or drooping eyes

 

Anyone expecting to get a nerve block should remember the risks are rare. Your experienced and vetted pain management doctor takes every precaution to minimize any risks associated with genicular nerve blocking.


Length of Pain Relief After a Nerve Block

After treatment, you'll experience immediate pain relief. The duration can last several days or a few weeks. Results vary from one patient to the next. Some patients experience relief from one injection. Others require multiple nerve block treatments.


What to Expect After Treatment

Following treatment, your doctor will request you monitor the pain levels. Relief from pain occurs almost immediately after an injection. This relief should last at the very least a few hours.

 

If your clinician feels the reaction's good, that treatment resulted in significant pain relief, they may determine you're a candidate for the advanced nerve ablation. That's a process that cauterizes the nerves. A genicular nerve ablation can provide relief from pain for up to 18 months.


Alternative At-Home Treatment

While you can accept treatment for knee pain from your doctor, some at-home treatments may also help to lessen pain.


Weight Loss

The less amount you apply to your knee joints, the greater chance of improving the health of your knee. OARSI, and osteoarthritis foundation, recommend, over a 20-week period, you lose five percent of your weight.


Manage Movement

Performing strengthening exercises will improve your knee's mobility and function. It can relieve stiffness and pain. Aquatic aerobics and yoga can be helpful.


Cold and Heat Therapy

Physical therapy can show you how to use hot and cold therapy to manage stiffness and pain.


Assistive Devices

Where there's limited mobility because of knee arthritis, your occupational or physical therapist may recommend helpful tools. One example is a custom knee brace or walker.


Natural Remedies

Doctors may prescribe supplements or acupuncture for pain. Acupuncture looks to be an effective and helpful option when it comes to arthritis knee pain.


Pain Relievers

Ibuprofen, aspirin, and other nonsteroidal anti-inflammatory medications can help with osteoarthritis knee pain and inflammation. Your doctor can recommend appropriate doses for self-treatment.

Winter, widely considered the season of comfort, is the time for indoor relaxation and quiet contemplation. However, winter also brings with it some very real dangers, including cold, dark, and slippery surfaces. For older adults or those dealing with chronic pain, a small slip on these surfaces can lead to serious injuries that take months to heal. The good news? You can train your body to handle these challenges. Let’s explore some simple, safe exercises you or your loved ones can do from the comfort of your home to build your winter-proof stability. Why Winter Increases the Risk of Falls Cold weather brings more than just chilly air. It changes the way we move, how our muscles respond, and even how we think about walking. When it’s icy, people tend to tense up, take shorter steps, and look down more often. Muscles also get tighter in the cold, which reduces flexibility. Plus, all those bulky layers of clothes mess with your center of gravity and limit how quickly you can react if you start to lose your balance. Your boots might be waterproof and warm, but they're probably not giving you the ankle support or ground feel you'd get from your regular shoes. Then there's the simple fact that many of us move less in winter. Maybe you skip your daily walks when it's freezing, or you stop going to that exercise class because driving feels too risky. But here's the catch: the less you move, the weaker you get, and the weaker you get, the more likely you are to fall. Building a Foundation To prevent this, you simply need to work on two main things: balance and strength. Physical therapy and balance-focused exercises train your muscles, joints, and nervous system to respond faster and more effectively when something throws you off. Balance Training Balance isn’t just about standing still without wobbling. It’s about how your body reacts when something throws it off center. When you step on ice, for example, your brain and muscles have to communicate in an instant to keep you upright. If that connection is slow or weak, you’re more likely to fall. Some simple ways to train your balance include: ● Single Leg Stands : Stand near a sturdy surface like a countertop or wall for support. Lift one foot slightly off the ground and hold that position for 10–15 seconds. Then switch sides. At first, you might wobble, but that’s perfectly normal. Over time, your legs, ankles, and core muscles will get stronger, and your balance will improve. Try doing 3 rounds on each leg daily. ● Heel-to-Toe Walk: Imagine you’re walking on a tightrope. Place one foot directly in front of the other, heel touching toe, as you move slowly across the room. This simple drill strengthens your stabilizing muscles and sharpens coordination. Keep your eyes forward, not down, and use a wall for light support if needed. ● Side Leg Raises: Hold onto a sturdy chair or counter. Lift one leg out to the side while keeping your back straight and your toes facing forward. Lower it slowly and repeat. This exercise builds hip strength, which plays a big role in staying upright on slippery ground. ● Weight Shifts: Stand with your feet hip-width apart and shift your weight from one leg to the other slowly. Feel your balance change from left to right. This gentle exercise teaches your body to adjust quickly. Strength Training Balance and strength go hand in hand. When your muscles are strong, they act like shock absorbers, keeping you stable even when your footing isn’t perfect. Focus on the muscles that support your posture and help you move safely. Here are a few simple exercises to include in your daily routine: ● Chair Squats: Sit down and stand up from a sturdy chair without using your hands for support. Keep your feet flat on the floor and your knees aligned with your toes. This move strengthens your thighs, hips, and glutes—key muscles for stability and control. ● Heel Raises: Stand behind a chair or counter and slowly lift your heels so you’re standing on your toes. Lower back down after holding for a few seconds. This helps strengthen your calves and ankles, improving the small muscle reactions that keep you upright when you slip. ● March in Place: Lift your knees high as if you’re marching. Do this for one to two minutes, rest, and repeat. Marching builds leg endurance and helps train your coordination. ● Core Squeezes: While sitting or standing, tighten your stomach muscles as if you’re zipping up a snug jacket. Hold for 10 seconds, then release. A strong core helps your upper and lower body work together to keep you balanced. These movements may look simple, but they’re powerful. Doing them for just 10–15 minutes a day can make winter walks safer and less stressful. Warming Up Before You Head Outdoors Cold weather tightens muscles and slows blood flow, making your body less responsive. That’s why warming up before heading outside is so important. Think of it as insurance against sudden slips. Try a short warm-up routine before stepping out: ● Arm circles to loosen shoulders. ● Gentle knee bends to wake up leg muscles. ● Shoulder rolls and neck stretches to improve mobility. ● A quick indoor walk or stair climb to raise your heart rate slightly. It’s also wise to check your footwear. Look for rubber soles with deep treads for better traction. Avoid smooth or worn-out shoes, and consider ice grips that attach to your boots if you live in a particularly snowy area. Winter doesn't have to be a season of fear. By investing just 10-15 minutes a day in these simple, safe exercises, you can build the strength and confidence you need to navigate the season safely. You are giving your body the tools it needs to stay upright, stable, and strong. When to Ask for Professional Help If you’ve had a fall before or feel nervous about losing your balance, it’s a good idea to get help from a physical therapist or pain specialist. They can assess your movement patterns and create a personalized exercise plan to strengthen weak areas. At Pain Treatment Centers of America , we often see patients who avoid movement due to fear of falling or pain. With guided therapy, they rebuild strength and confidence. Therapists also teach safe walking techniques, posture corrections, and stretching routines that make winter mobility much easier. Even if you’re recovering from an injury or dealing with chronic conditions like arthritis, a professional can tailor exercises that improve stability without aggravating pain. Our team at Pain Treatment Centers of America can provide you with the comprehensive care you need to manage your pain. Contact us to book an appointment!
