Living with Chronic Pain - How to Coexist with Pain That Won't Go Away

What Is Chronic Pain?

The International Association for the Study of Pain (IASP) defines pain lasting more than 3 months as "chronic pain." In Japan, about 20% of adults (approximately 20 million people) suffer from chronic pain, with lower back pain, stiff shoulders, headaches, joint pain, and neuropathic pain being the most common.

Acute pain is a warning signal that "the body is damaged," but chronic pain is different. When pain persists after tissue damage has healed, it means the nervous system has shifted into a state of "continuously sending pain signals." The pain processing circuits in the brain and spinal cord become hypersensitive, and stimuli that should not be painful are perceived as pain - a phenomenon called "central sensitization." Understanding this itself is the first step to change how you relate to pain.

How Chronic Pain Affects Mental Health

Comorbidity with Depression

About 30-50% of chronic pain patients also develop depression. Pain causes depression, and depression heightens pain sensitivity, forming a bidirectional vicious cycle. Serotonin and norepinephrine are involved in both mood regulation and pain suppression, so reduced function of these neurotransmitters worsens both depression and pain.

Social Isolation

"I can't go out because of the pain." "I keep canceling plans." "Nobody understands my pain." Chronic pain restricts social activities and deepens isolation. The lack of understanding from others - "but you look fine" - further intensifies the sense of isolation. (Books on chronic pain can deepen your understanding)

The Vicious Cycle with Sleep Disturbance

Chronic pain causes difficulty falling asleep and frequent nighttime awakenings, significantly degrading sleep quality. Sleep deprivation lowers the pain threshold the following day, making even milder stimuli feel painful. Breaking this vicious cycle of "can't sleep because of pain, pain worsens because of poor sleep" is one of the crucial pillars of treatment.

Common Misconceptions and Pitfalls

"The Pain Is All in Your Head" Is Wrong

Chronic pain patients are sometimes told by healthcare professionals or people around them that it's "just psychological" or "all in your head." Central sensitization is a real change in the nervous system, and the pain objectively exists. Patients told "it's all in your head" lose trust in medicine and distance themselves from appropriate treatment, making this misconception harmful.

The Harm of "Continued Bed Rest"

Keeping a painful area immobile for extended periods leads to muscle weakness, reduced joint range of motion, and worsened blood circulation, actually making pain more chronic and severe. While "rest if it hurts" was once conventional wisdom, modern pain medicine recommends "moving within what is possible."

Risks of Long-term Daily Painkiller Use

Taking over-the-counter painkillers daily for extended periods increases the risk of medication-overuse headache (MOH) and other side effects. Painkillers are effective for acute management but do not fundamentally resolve chronic pain. If you are using painkillers more than 10 days per month, consider visiting a pain clinic (specialized pain outpatient department).

Four Approaches to Living with Chronic Pain

1. Pain Education (Pain Neuroscience Education)

Research has shown that understanding the mechanisms of chronic pain itself contributes to pain reduction. Shifting from "pain = tissue damage" to "pain = nervous system hypersensitivity" reduces fear of pain and decreases avoidance behavior. This knowledge can be obtained from physicians or physical therapists, or learned through reliable educational programs.

2. Gradual Resumption of Activity

With chronic pain, people tend to avoid activity out of fear of pain (fear-avoidance behavior). However, reduced activity leads to decreased muscle strength, decreased flexibility, and worsened mood, which further worsens pain. Under the guidance of a physical therapist, gradually increasing activity within a tolerable pain range leads to long-term improvement. The key is not "waiting until pain reaches zero" but a paradigm shift to "moving while coexisting with pain."

3. Psychological Approaches

Cognitive behavioral therapy (CBT) for chronic pain aims not to eliminate pain itself but to change how you relate to pain. Shifting from "I can't do anything because of pain" to "there are things I can do even with pain" - this cognitive shift significantly improves quality of life. Acceptance and Commitment Therapy (ACT) has also been reported to be highly effective for chronic pain. Practicing mindfulness also changes how attention is directed toward pain and contributes to reducing suffering.

4. Multidisciplinary Approach

Treating chronic pain has limitations with any single method. Pharmacotherapy (analgesics, antidepressants, anticonvulsants), physical therapy, psychotherapy, exercise therapy, acupuncture, mindfulness. Combining these in "multidisciplinary pain management" is considered the most effective approach. Pain clinics (specialized pain outpatient departments) offer this multidisciplinary approach. (Books on pain management are also a good reference)

Comparison of Treatments

• Pharmacotherapy: Provides immediate relief but is symptomatic. Long-term continuous use requires caution
• Cognitive behavioral therapy (CBT): Changes cognition and behavioral patterns toward pain. Has high long-term effectiveness
• Exercise therapy: Restores muscle strength and flexibility, raising the pain threshold. Consistency is key
• Acupuncture: Has reported effectiveness in pain reduction with minimal side effects
• Mindfulness: Eases excessive attention to pain and reduces the subjective intensity of suffering

Since the optimal combination varies greatly between individuals, it is important to build a personalized plan in consultation with a pain clinic specialist.

Next Steps

Chronic pain tends to worsen when carried alone. If pain has persisted for more than 3 months, start by asking your primary care physician for a referral to a pain clinic. Letting go of the mindset that "pain is something to endure" and seeking professional help is not weakness - it is an act of reclaiming your life.

Summary

Chronic pain is something to "manage" rather than "cure." Understand the mechanisms of pain, gradually resume activity, incorporate psychological approaches, and combine multiple treatments. Even if pain doesn't reach zero, it is possible to reclaim your quality of life.
