Complex Regional Pain Syndrome: What It Is and How It’s Treated

A woman is sitting on the ground holding her ankle in pain.

Picture it: you recently received a nasty cut to the arm. You treat the cut as you would any other, but then you notice that even the slightest touch near the cut over the next couple of days causes severe pain, far more than you would think normal for a cut that big or small. This feeling stays around, even months after the cut has healed.


This might be an instance of Complex Regional Pain Syndrome.


What Is Complex Regional Pain Syndrome?

Complex Regional Pain Syndrome, or CRPS, is a condition that can be difficult to understand. In the past, it was referred to both as reflex sympathetic dystrophy (RSD) and causalgia, but now more is known about this condition. Simply put, CRPS is an overarching term that refers to excess and prolonged pain and inflammation that follow an injury to an arm or leg. There are two forms, one of which is acute (short-term) and the other chronic (where it lasts longer than six months or half a year). This pain can be debilitating to the point where you might not even be able to use the extremity you are experiencing it in.

 

In order to fully understand CRPS, let's first take a look at how it manifests so you will know what to look out for following an arm or leg injury.


What Are the Symptoms of CRPS?

The reason this condition is difficult to understand is that there can be a range of pain symptoms, anything from spontaneous pain or excess pain that is far greater than normal following a mild touch or brush of the extremity. CRPS can also be accompanied by changes in temperature, skin color, and even swelling below the site of the injury.

 

CRPS happens in extremities such as the arm or the leg, and while it typically improves as time goes on to the point that it often goes away, in some cases it lingers or is more severe, making it quite debilitating.


What Causes CRPS?

One of the most frustrating things about CRPS is how it can affect some people with the same injuries as others while not affecting the other injured parties as well. Because of this, there is no real known “cause” for CRPS, but it presents itself after the sufferer has received an injury to an extremity. Researchers have realized the cause is due to the dysfunction of or damage to the injured peripheral sensory neurons through this correlation.

 

The nervous system is composed of the brain and spinal cord, and the peripheral nervous system makes the nerve signals from the brain and spinal cord spread to all other parts of the body. This means that, when the neurons are damaged or not functioning properly, the signal of severe pain is transmitted.

 

Pain is our body trying to warn us against dangers. These can be both external (pain from holding your hand too close to a fire) or internal (a headache). CRPS occurs when the nervous system is given incorrect information about the level of pain currently being experienced by the extremity, which can lead to acute or chronic bouts of extreme pain to the point where it becomes debilitating.


Most Common Injuries That Lead to CRPS

While it is unclear what causes CRPS, certain injuries are more commonly paired with it than others:


●      Fractures. When dealing with wrist fractures especially, the nerves can become injured. Add to that a cast that’s too tight, and CRPS might come about. Casts that are painful or too tight to wear should be immediately replaced because of this.

●      Surgery. Due to the nature of surgery—needing to get into the body in a way that is not natural, such as a surgical incision, and even the presence afterward of sutures—the nerves can get damaged, which in turn will bring about CRPS. Even if the surgery itself goes perfectly fine, CRPS can still pop up because of the nerve damage.

●      Sprains/strains. Even if the injury is internal, CRPS can come along. This is due to the fact, during a sprain or strain, the connective tissue ruptures, leading to trauma and excess movement that can stretch nearby nerves and cause damage and dysfunction of the neurons.

●      Lesser injuries such as burns or cuts. Similar to the small incisions needed sometimes for surgery, smaller injuries can also cause CRPS. So long as the nerves that are just underneath are damaged, no matter how big or little the burn or cut, CRPS can be activated.


How Is CRPS Treated?

While CRPS might seem scary, there are ways to go about treating it. Methods have been used before that have been proven ineffective, but now that medical professionals have done more research on the causality of CRPS, it can be treated more effectively. Here are some of the more common—and effective—ways used to treat CRPS today:


●      Physical Therapy: Through physical rehabilitation, the symptoms of CRPS can be managed, and the risk of long-term physical problems can be avoided.

●      Pain Management: Treating the pain itself can be done by a medical professional, to the point where excessive bouts of pain from CRPS can be made much more tolerable. A procedure such as wireless peripheral nerve stimulation is one way pain can be managed.

●      Spinal Fluid Drug Pumps: Due to the nature of the nervous system, those with chronic pain, such as those with CRPS, can be treated with pain pumps. The pump directly provides pain medication to the spinal fluid, which in turn can be sent along the nervous system so that sufferers can find relief.


What Should I Do if I Think I Have CRPS?

The best thing to do if you think you might be suffering from CRPS is to consult a medical professional. At PTCOA, we can help diagnose you so that the root cause of your pain can be found and treated, letting you get back to normal that much quicker. This can be done through a detailed examination and procedures such as imaging nerves by ultrasound or MRI (magnetic resonance imaging), along with a few more, to help find the region that is fully affected by CRPS and treat it properly.

Chronic or acute pain has the potential to significantly impact your daily life, making even everyday tasks a hassle. Pain Treatment Centers of America believes that knowing your medication options is a crucial step in building an appropriate, personal pain management strategy. While many treatment options are available, pharmacologic therapy has been the peak of comprehensive care. Types of Medications Used in Pain Management Pain medications are not universalized. The selection of the right prescription depends on the pain type, severity, and medical history. Common categories include: 1. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) NSAIDs, such as ibuprofen or naproxen, tend to be the first line of defense for low levels of pain. They reduce swelling and provide comfort associated with conditions like arthritis, back pain, or joint injuries. In some patients, however, they can affect the stomach or kidneys. Therefore, careful studying and dosing guidance from a professional is key. 2. Acetaminophen Acetaminophen is mostly for general pain reduction and is sometimes combined with other treatments. Unlike NSAIDs, it doesn’t target swelling. Nonetheless, it can be effective for pain relief and daily improvement. 3. Muscle Relaxants For pain caused by muscle spasms or tension, muscle relaxants can provide relief. These medications work by calming overactive muscles and are usually prescribed for short-term use to prevent dependency or side effects. 4. Antidepressants and Anti-Seizure Medications Certain antidepressants and anti-seizure drugs can treat neuropathic (nerve) pain. They work by altering how the nervous system processes signals of pain throughout your body. Even if you do not experience depression or seizures, these medications assist with pain control. 5. Opioids Opioids are strong pain-relieving medications chosen for more potent pain when other options aren’t doing the trick. At Pain Treatment Centers of America, we practice strict guidelines to minimize risks, evaluate patient progress, and ensure healthy, responsible use. A combination of Opioids can be introduced to other treatments as part of a multimodal pain management plan. Personalized Pain Management The effectiveness of medications is best when combined with other therapies; physical therapy, interventional procedures, and lifestyle changes. We work closely with each patient to structure a plan that focuses on the root cause of pain, not just the signs. Every treatment plan is carefully engineered, giving thought to variables like medical history, existing conditions, and possible side effects. Patients are taught how to use the medication safely, dosing schedules, and expectations of each prescription. Take the Next Step Understanding your medication options enables you to take charge of your pain and improve your life overall. If you’re having issues with chronic or acute pain, our professionals at Pain Treatment Centers of America will gladly help. We mix the most up-to-date pharmacologic therapies with personalized care to provide comfort, improve function, and enhance your total well-being.

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!
