The Complex Relationship Between Stress and Pain (And How to Manage Both)

Pain is a universal experience, and yet, it’s uniquely personal to each of us. Whether it’s the sharp sting of a migraine, the dull ache of back pain, or the deep throb of joint pain, there’s no one-size-fits-all when it comes to pain. As a runner who is currently sidelined because of chronic achilles pain, I know just how frustrating pain can be!

One thing is clear, though: stress and pain are often intertwined in ways that can make both harder to manage. In this post, we’ll dive into types of pain, how stress can exacerbate pain, and what we can do to regain balance.

Stress and Pain: How One Feeds the Other

The relationship between stress and pain is a bit of a vicious cycle. Stress activates your body’s fight-or-flight response, a mechanism designed to keep you safe from danger. While useful in life-threatening situations, chronic stress keeps this system on overdrive, flooding the body with stress hormones like cortisol and adrenaline. These hormones have a range of effects, from increasing inflammation to tightening muscles, which can make existing pain worse.

When we’re stressed, our brain is more likely to interpret pain signals as severe, creating a feedback loop where pain becomes more intense the more stressed we are. Stress doesn’t just affect how we feel pain—it can change the actual intensity and duration of the pain.

For instance, studies show that people dealing with high levels of stress may have a lower pain threshold, meaning they experience pain more easily. A headache that might be mild under normal conditions could feel excruciating during a stressful week at work. Similarly, chronic stress can contribute to muscle tension, which in turn leads to more physical pain—think of how often stress manifests as tight shoulders, neck pain, or tension headaches.

Chronic Pain: A Modern Epidemic

Now, let’s talk about chronic pain, which has become an increasingly widespread issue, particularly in our fast-paced society. Chronic pain is pain that lasts for three months or longer, and it can stem from various conditions—anything from injury to illness. But there’s one form of chronic pain that stands out due to its prevalence: back pain.

In today’s world, chronic back pain has become a common issue, affecting millions of people globally. Whether it’s due to long hours of sitting, poor posture, or physically demanding jobs, back pain has steadily crept into the lives of many. And with the rise of desk jobs and our increasingly sedentary lifestyles, it’s no surprise that back pain is one of the leading causes of disability worldwide.

Chronic back pain isn’t just a physical burden; it comes with a psychological toll. The constant discomfort can interfere with daily activities, disrupt sleep, and even affect mental health. Living with long-term pain often leads to feelings of frustration, helplessness, and stress, further fueling the cycle of pain and distress.

How Stress Worsens Chronic Pain

Here’s where the connection between pain and stress becomes even more evident. Chronic pain increases stress, which in turn worsens the pain. It’s a bit of a chicken-and-egg scenario: Does the pain cause stress, or does stress cause pain? The answer is both.

Stressful situations can intensify chronic pain by increasing muscle tension, inflammation, and the release of cortisol. Over time, this stress-induced pain cycle can make it harder for the body to recover, keeping you in a loop where the pain never fully subsides.

But here’s some good news: breaking the stress-pain cycle is possible. By learning to manage stress, you can significantly reduce how much it affects your pain.

Types of Pain: Allodynia and Hyperalgesia

Before we go further, it’s worth understanding the types of pain people experience. Not all pain is created equal, and stress affects these sensations in different ways.

  • Allodynia is pain triggered by something that normally shouldn’t hurt—like a light touch or a cool breeze. In individuals with heightened pain sensitivity, even minimal stimuli are perceived as painful because their nerves react to lower and lower levels of stimulus intensity due to altered nerve responses.
  • Hyperalgesia refers to an increased sensitivity to pain. Even normal pain signals (like a small cut or bump) can become exaggerated, causing intense discomfort. This condition often occurs when nerve pathways have been damaged or altered, and stress can make hyperalgesia even worse.

Understanding that pain is not only physical but also a perception in the brain is key. Emotional stressors like anxiety or fear can increase the brain’s sensitivity to pain signals, making the experience more intense.

The Connection Between Sleep, Pain, and Stress

Sleep is often the first casualty of stress, and it plays a huge role in how we experience pain. Chronic pain disrupts sleep, and poor sleep can make both pain and stress worse, creating a vicious cycle. Research shows that sleep deprivation increases pain sensitivity, meaning even minor aches and pains can feel magnified after a restless night.

During sleep, our bodies repair tissues, reduce inflammation, and restore energy levels—all of which are vital for managing pain. Without enough sleep, the body doesn’t have a chance to recover properly, which can prolong pain and keep stress levels high. Higher levels of the stress hormone cortisol are also associated with poor sleep, further exacerbating both stress and pain.

To improve sleep and break this cycle, consider adopting better sleep hygiene habits:

  • Establish a consistent sleep routine
  • Limit screen time before bed
  • Create a relaxing pre-sleep ritual (like reading, meditation, or light stretching)
  • Make your sleeping environment as comfortable as possible (supportive pillows, a good mattress, and a dark room)

Nutrition’s Role in Pain and Stress

What we eat can either fuel the fire of stress and pain—or help extinguish it. Inflammatory foods such as refined sugars, processed snacks, and trans fats can worsen both pain and stress. Chronic inflammation in the body is linked to many pain conditions, including joint pain, headaches, and muscle aches.

On the flip side, anti-inflammatory foods like leafy greens, berries, nuts, and fatty fish can help reduce inflammation and pain. For instance, foods rich in omega-3 fatty acids (found in salmon, walnuts, and flaxseeds) have been shown to lower inflammation, which can help ease chronic pain.

Certain nutrients are also known for their stress-relief properties:

  • Magnesium (found in spinach, almonds, and dark chocolate) helps to calm the nervous system.
  • Antioxidants (like those in blueberries and turmeric) reduce oxidative stress, another contributor to pain.

By focusing on a nutrient-dense, anti-inflammatory diet, you can support both your body’s pain management processes and its ability to handle stress more effectively.

Emotional Pain vs. Physical Pain: Stress Amplifies Both

Pain isn’t just a physical experience—emotional pain can manifest in ways that feel very real to the body. Grief, anxiety, and depression often trigger physical symptoms like muscle tension, headaches, and chest pain.

In fact, emotional pain is processed in the same areas of the brain that handle physical pain. This means that emotional stress can make physical pain feel more intense, and physical pain can heighten emotional distress.

Recognizing this mind-body connection is crucial. Healing emotional pain (through therapy, mindfulness, or emotional release techniques) can reduce physical discomfort. Similarly, reducing physical pain can help ease emotional turmoil, creating a positive feedback loop for well-being.

Chronic Pain and Central Sensitization: How Stress Fuels the Process

Chronic pain often begins as a response to an injury or illness but can evolve into something more complex over time. In many cases, chronic pain is due to a process called central sensitization, where the nervous system becomes hypersensitive to pain signals. This hypersensitivity develops when the brain and spinal cord become overly reactive to pain due to repeated activation. Stress plays a pivotal role in driving and intensifying this process.

Stress: The Amplifier of Pain Sensitivity

Stress—whether from emotional trauma, anxiety, or even daily challenges—acts as a trigger that keeps the nervous system on high alert. When you’re under stress, the body releases hormones like cortisol and adrenaline, which are part of the “fight or flight” response. In the short term, these hormones are meant to protect you. However, when stress becomes chronic, it pushes the nervous system into overdrive, amplifying pain signals and making it harder to regulate them. Essentially, stress feeds into the cycle of central sensitization, worsening pain perception and contributing to a heightened, ongoing pain response.

How Stress Contributes to a Learned Pain Response

Central sensitization occurs when pain symptoms develop due to unique factors—such as injury, stress, or emotional trauma. Over time, the repeated activation of the pain response leads the brain and body to “learn” to respond to stimuli with pain, even when no tissue damage is present. Stress reinforces this learned response by constantly triggering the release of stress hormones, which increases the sensitivity of the nervous system to pain signals. This can make even minor stimuli feel painful, a phenomenon known as central sensitization syndrome. Conditions commonly associated with central sensitization include:

  • Migraines
  • Back pain
  • Fibromyalgia
  • Chronic fatigue syndrome (ME/CFS)
  • Complex regional pain syndrome (CRPS)
  • Sciatica
  • Irritable bowel syndrome (IBS)
  • Trigeminal neuralgia
  • Tension headaches
  • Depression, anxiety, and insomnia

Any symptom lasting more than six months without clear signs of tissue damage could indicate central sensitization, often driven by chronic stress.

The Vicious Cycle of Stress and Pain

The connection between stress and pain is a two-way street. The more pain you experience, the more stressed you become, and vice versa. This creates a vicious cycle where stress magnifies pain, and pain intensifies stress, making it difficult to break free from the grip of chronic pain. Factors that worsen this cycle include:

  • Stressful life experiences: Emotional stressors, trauma, or ongoing challenges can increase your pain sensitivity, keeping your nervous system in a constant state of overdrive.
  • Mental health issues: Depression, anxiety, and social isolation are closely linked to chronic pain and can make the experience more intense and harder to manage.
  • Decreased ability to engage in enjoyable activities: When pain limits what you love to do, it creates a negative feedback loop that amplifies both stress and pain.
  • Overexertion or underexertion: Pushing your body too hard or avoiding movement altogether can trigger more pain, as your nervous system struggles to recalibrate, especially when stress is a factor.

Managing Stress to Break the Pain Cycle

Since stress plays such a significant role in amplifying pain through central sensitization, managing it is crucial to breaking the cycle of chronic pain. Mind-body therapies like meditation, deep breathing, and progressive muscle relaxation can help calm the nervous system, reducing its sensitivity to pain signals. By retraining your brain and nervous system to interpret pain signals as less threatening, you can reduce the grip of chronic pain. Techniques such as cognitive-behavioral therapy (CBT) and mindfulness can also be powerful tools in managing stress and, in turn, reducing the central sensitization response.

A Brain-Based Approach to Managing Pain

The good news is that by retraining your brain, you can reduce or even eliminate chronic pain symptoms. By teaching the brain to reinterpret pain signals as safe, you can disrupt the learned pain response and lower stress-related amplification of pain. This brain-based approach helps the nervous system reset, allowing you to break free from the cycle of chronic pain and stress.

Retrain Your Brain to Reduce Symptoms

Breaking the stress-pain cycle is possible. By learning to manage stress, you can significantly reduce how much it affects your pain.

Several techniques can help your brain unlearn its hypersensitivity to pain:

  • Cognitive Behavioral Therapy (CBT): This helps shift how you think about pain, focusing less on the discomfort and more on positive coping mechanisms.
  • Mind-body therapies: Activities like yoga, meditation, or deep breathing exercises can calm the nervous system and improve resilience.
  • Visualization exercises: Practicing mental imagery, such as visualizing your body healing, can reinforce the brain’s perception that it’s safe to reduce pain.
  • Pain journaling: Keeping track of your pain, emotional responses, and triggers can help identify patterns and areas for improvement.
  • Progressive Muscle Relaxation (PMR): This technique involves tensing and relaxing different muscle groups to help release physical tension and improve body awareness, which can reduce pain perception.

By incorporating these techniques, you can begin to retrain your brain, teaching it to interpret pain signals more accurately and reduce the impact of chronic pain on your life.
