Almost everyone experiences pain at some point, but for a significant share of adults, pain doesn't resolve on its own. It lingers, recurs, or becomes a near-constant presence in daily life. That's chronic pain, and understanding what causes it, and what can actually be done about it, is the first step toward getting real relief.This guide covers what makes pain "chronic" rather than temporary, the most common underlying causes, how chronic pain is diagnosed, and the full range of treatment options available today, including where to go deeper on any specific condition.

What Makes Pain "Chronic"?

Pain is generally considered chronic when it persists for longer than three months, well beyond the typical time it takes tissue to heal from an injury or illness. This distinguishes it from acute pain, which has a clear, recent cause (a sprain, a surgery, an infection) and an expected timeline for improvement.

Chronic pain is different in a few important ways:

  • It can persist even after the original injury or cause has healed.
  • It sometimes has no single identifiable trigger, or multiple contributing factors layered together.
  • It often affects sleep, mood, work, and relationships, not just the physical sensation of pain itself.
  • The nervous system itself can become more sensitized over time, a process called central sensitization, which can make pain feel more intense than the underlying tissue damage would suggest.

Understanding this distinction matters because chronic pain usually requires a different, more comprehensive treatment approach than a short course of rest and medication.

Common Causes of Chronic Pain

Chronic pain can stem from a single, identifiable source or a combination of factors. The most common causes we see include:

  1. Degenerative spine conditions, such as herniated discs, spinal stenosis, and facet joint arthritis, which can cause chronic low back pain or neck pain.
  2. Nerve-related pain, including sciatica and other forms of radiculopathy, where a compressed or irritated nerve causes pain that radiates beyond its original source.
  3. Osteoarthritis and other joint conditions, which gradually wear down cartilage and cause pain that gets worse with activity over months or years. Our guide on the top causes of joint pain covers this in more depth.
  4. Old or improperly healed injuries, including sports injuries that weren't fully rehabilitated, which can develop into chronic pain long after the original event.
  5. Autoimmune and inflammatory conditions, such as rheumatoid arthritis, where the immune system itself drives ongoing joint pain and inflammation.
  6. Central sensitization, a state where the nervous system amplifies pain signals, sometimes developing after a prolonged period of untreated or undertreated pain from any of the causes above.

How Chronic Pain Is Diagnosed

Because chronic pain can have layered or overlapping causes, an accurate diagnosis usually takes more than a quick exam. A thorough evaluation typically includes:

  • A detailed history, covering when the pain started, how it's evolved, what makes it better or worse, and what's already been tried.
  • A physical exam, assessing movement, strength, and specific pain-generating structures.
  • Imaging, such as X-ray, MRI, or CT, when structural causes are suspected.
  • Diagnostic injections, in some cases, used both to confirm the exact source of pain and, often, to treat it at the same time.

This diagnostic process is the foundation of effective chronic pain treatment. Treating the wrong structure, even with a reasonable-sounding treatment, rarely provides lasting relief.

Treatment Options for Chronic Pain

Chronic pain treatment today spans several categories, most effective plans draw from more than one.

1. Movement and Rehabilitation

Physical therapy, guided exercise, and activity modification address the mechanics behind chronic pain and are the foundation of most treatment plans, whether pain started from an old injury, arthritis, or spine degeneration.

2. Interventional Procedures

Image-guided treatments like epidural steroid injections, nerve blocks, and radiofrequency ablation target the specific structure generating pain directly, often providing relief that lasts months at a time. These sit between conservative care and surgery for patients who need more targeted treatment.

3. Regenerative Therapies

Treatments like PRP (platelet-rich plasma) and prolotherapy aim to support the body's own healing response in damaged tendons, ligaments, and joints, often used alongside other treatments rather than alone.

4. Non-Opioid Medication

Anti-inflammatory and nerve-pain-specific medications can play a supporting role in a broader treatment plan. Our guide on non-opioid pain management techniques covers this full category in detail, including why it's generally preferred over long-term opioid use for chronic conditions.

5. Mind-Body Support

Because chronic pain affects sleep, mood, and the nervous system's sensitivity to pain signals, approaches like cognitive behavioral therapy and improved sleep habits are often a meaningful part of a comprehensive plan, especially for pain that's been present for months or years.

6. Surgery, When It's Truly Needed

For most chronic pain conditions, surgery is the last consideration, not the first, reserved for cases with a clear structural problem that hasn't responded to a genuine trial of non-surgical treatment. A conservative-first specialist will always explore the options above before recommending a surgical evaluation.

How Integrative Sports & Spine Approaches Chronic Pain

Across our four Southern California locations, our physicians focus on identifying the exact source of chronic pain before recommending treatment, then building a plan that draws from the full range of options above. Patients choose us for:

  • Board-certified specialists. Our physicians, including Dr. Henry Lee, DO, Dr. Victoria Chang, MD, and Dr. Kamara Savage, MD, are trained specifically in interventional pain management and PM&R.
  • Precise, imaging-guided diagnosis rather than a one-size-fits-all protocol.
  • A full non-surgical toolkit, spanning physical therapy coordination, interventional procedures, and regenerative therapies.
  • A conservative-first philosophy that gives non-surgical treatment a genuine chance to work.
  • Four convenient clinic locations. Long Beach (2650 Elm Ave STE 210), Riverside (3975 Jackson St STE 201), Alhambra (925 S Garfield Ave), and City of Industry (18605 Gale Ave # 222).

Frequently Asked Questions

What's the difference between acute and chronic pain?
Acute pain has a clear, recent cause and typically resolves within the expected healing time, usually weeks. Chronic pain persists longer than three months, sometimes even after the original cause has healed, and often requires a broader treatment approach.

Can chronic pain be cured?
It depends on the underlying cause. Some chronic pain conditions can be resolved with the right diagnosis and treatment, while others are more effectively managed long-term to reduce pain and restore function, rather than eliminated entirely. An accurate diagnosis is the key first step either way.

Is chronic pain "all in my head"?
No. Chronic pain has a real physical basis, though the nervous system's response to pain can become more sensitized over time, which is a physiological process, not a sign the pain isn't real. Addressing both the physical cause and the nervous system's sensitivity is often part of effective treatment.

When should I see a specialist for chronic pain?
If pain has lasted more than a few weeks despite rest and basic self-care, or if it's affecting your daily activities, work, or sleep, it's worth getting an evaluation rather than waiting for it to resolve on its own.

Do I need to try opioids before other treatments?
No. Non-opioid approaches, including physical therapy, interventional procedures, and regenerative therapies, are generally the preferred starting point for chronic pain, both because they're often more effective long-term and because they avoid the risks associated with opioid use.
