When chronic pain becomes part of everyday life, many people begin searching for answers beyond temporary symptom relief. Medications may dull discomfort for a few hours, injections may provide short-term improvement, and surgeries may not always address why the pain developed in the first place. Functional medicine offers a different perspective—one focused on uncovering and correcting the underlying causes of chronic pain naturally.

At Complete Performance Chiropractic, patients receive a comprehensive, personalized approach designed to identify the deeper contributors to pain, inflammation, fatigue, mobility limitations, and chronic dysfunction. Under the leadership of Dr. Eric Leitman, the clinic combines chiropractic care, functional medicine, rehabilitation strategies, nutritional support, spinal decompression, laser therapy, and holistic wellness planning to help patients achieve long-term improvement rather than temporary relief.

Understanding Chronic Pain

Chronic pain is generally defined as pain lasting longer than three months. Unlike acute pain, which acts as a warning signal after injury, chronic pain often continues long after tissues should have healed. According to organizations like the Mayo Clinic, managing chronic conditions effectively requires addressing both physical and lifestyle factors.

It may affect:

• The lower back

• Neck and shoulders

• Knees and hips

• Sciatica and nerves

• Muscles and fascia

• Joints and connective tissues

• Head and facial structures

• The digestive and nervous systems indirectly

For many individuals, chronic pain becomes a cycle involving:

• Inflammation

• Muscle compensation

• Joint dysfunction

• Stress hormone imbalance

• Sleep disruption

• Reduced mobility

• Nervous system sensitization

• Nutritional deficiencies

• Lifestyle-related dysfunction

Traditional healthcare models often focus heavily on symptom suppression. Functional medicine aims to understand why symptoms developed in the first place.

What Is Functional Medicine?

Functional medicine is a patient-centered healthcare approach focused on identifying and addressing the root causes of disease and dysfunction rather than simply masking symptoms.

Instead of asking:

“What medication matches this symptom?”

Functional medicine asks:

“Why is this symptom occurring in the first place?”

This approach recognizes that the body’s systems are interconnected. Digestive health, inflammation, hormones, stress, sleep, nutrition, movement patterns, posture, and nervous system function all influence chronic pain.

At Complete Performance Chiropractic, functional medicine evaluations may examine multiple contributing factors simultaneously to create personalized treatment plans tailored to each patient’s unique condition and health history.

Why Chronic Pain Often Has Multiple Root Causes

Pain rarely develops from a single issue alone.

For example, someone with chronic lower back pain may also have:

• Poor posture

• Weak core muscles

• Chronic inflammation

• Nutritional deficiencies

• Sleep deprivation

• Stress-related muscle tension

• Digestive dysfunction

• Hormonal imbalance

• Repetitive strain injuries

• Joint instability

Functional medicine practitioners attempt to connect these pieces together.

This broader perspective helps explain why many people experience recurring pain despite medications, injections, or isolated treatments.

Common Root Causes of Chronic Pain

Chronic Inflammation

Inflammation is a natural healing response, but chronic inflammation may contribute to ongoing pain, stiffness, swelling, and tissue degeneration.

Inflammation may be influenced by:

• Poor nutrition

• Excess sugar consumption

• Processed foods

• Stress

• Sedentary lifestyles

• Sleep disorders

• Autoimmune dysfunction

• Food sensitivities

• Obesity

• Chronic injuries

Functional medicine frequently emphasizes reducing inflammatory triggers naturally.

Poor Joint Mechanics and Spinal Dysfunction

Improper spinal alignment and restricted joint movement may increase stress on muscles, nerves, ligaments, and discs.

At Complete Performance Chiropractic, chiropractic adjustments aim to restore normal movement patterns and improve nervous system communication.

When joint mechanics improve, patients may experience:

• Better mobility

• Reduced muscle tension

• Improved posture

• Less nerve irritation

• Improved physical performance

Nervous System Dysregulation

The nervous system controls pain perception, muscle activity, stress responses, and healing processes.

Long-term stress may increase:

• Muscle tension

• Cortisol imbalance

• Fatigue

• Inflammation

• Sleep disturbances

• Pain sensitivity

Research suggests chronic pain conditions may involve altered nervous system processing and increased sensitivity to pain signals.

Functional medicine frequently incorporates stress reduction, sleep optimization, movement therapy, and nervous system support into care plans.

Nutritional Deficiencies

Deficiencies in nutrients such as:

• Magnesium

• Vitamin D

• Omega-3 fatty acids

• B vitamins

• Antioxidants

may contribute to muscle dysfunction, inflammation, fatigue, and poor tissue healing.

Functional medicine practitioners often assess dietary habits and may recommend nutritional modifications to support recovery.

Gut Health and Chronic Pain

The digestive system influences:

• Inflammation

• Immune function

• Nutrient absorption

• Hormonal balance

• Neurotransmitter production

Poor gut health may contribute to systemic inflammation and pain disorders.

Some patients experience improvement when addressing:

• Food sensitivities

• Digestive dysfunction

• Poor microbiome balance

• Chronic bloating

• Irritable bowel symptoms

Conditions Functional Medicine May Help Address

Functional medicine may support patients experiencing:

• Chronic lower back pain

• Neck pain

• Sciatica

• Fibromyalgia

• Arthritis

• Joint pain

• Muscle tension

• Migraines and headaches

• Chronic fatigue

• Neuropathy

• Tendonitis

• Sports injuries

• Auto accident injuries

• Postural dysfunction

• Inflammatory conditions

At Complete Performance Chiropractic, treatment plans are individualized based on each patient’s condition, goals, lifestyle, and contributing health factors.

Functional Medicine and Chiropractic Care: A Powerful Combination

One reason many patients seek care at Complete Performance Chiropractic is the clinic’s integrated approach.

Rather than relying on one therapy alone, multiple therapies may be combined to create synergistic benefits.

These may include:

• Chiropractic adjustments

• Functional medicine evaluations

• Nutritional consultations

• Spinal decompression

• Corrective exercises

• Laser therapy

• Shockwave therapy

• Acupuncture

• Rehabilitation strategies

• Lifestyle coaching

This multimodal approach may help improve both short-term relief and long-term function.

Chiropractic Adjustments and Pain Relief

Chiropractic care focuses on restoring proper joint motion and spinal alignment.

According to Complete Performance Chiropractic, chiropractic adjustments may help reduce:

• Neck pain

• Back pain

• Headaches

• Joint stiffness

• Mobility restrictions

• Postural strain

Adjustments may also improve nervous system function by reducing interference affecting communication between the brain and body.

Functional Rehabilitation and Corrective Exercise

Pain relief alone is often not enough.

Weak muscles, poor movement patterns, and instability may cause symptoms to return repeatedly.

Corrective rehabilitation programs may help patients:

• Improve mobility

• Strengthen stabilizing muscles

• Enhance flexibility

• Restore posture

• Prevent reinjury

• Improve athletic performance

At Complete Performance Chiropractic, rehabilitation strategies are personalized according to patient needs and activity levels. To learn more about our foundational philosophies, you can read our blog.

Spinal Decompression Therapy

Non-surgical spinal decompression is commonly used for:

• Herniated discs

• Degenerative disc disease

• Sciatica

• Chronic lower back pain

• Disc-related nerve compression

This therapy gently stretches the spine to reduce pressure on discs and nerves.

Patients often seek spinal decompression when they want alternatives to surgery or injections.

Laser Therapy and Tissue Healing

Laser therapy uses specific wavelengths of light to stimulate tissue repair and reduce inflammation.

Benefits may include:

• Improved circulation

• Reduced swelling

• Faster healing

• Reduced pain

• Enhanced tissue regeneration

At Complete Performance Chiropractic, laser therapy may be integrated into broader functional rehabilitation plans for chronic injuries and musculoskeletal pain.

Shockwave Therapy for Chronic Injuries

Shockwave therapy uses acoustic waves to stimulate healing in damaged tissues.

It may help treat:

• Plantar fasciitis

• Tennis elbow

• Tendon injuries

• Hip pain

• Chronic muscle tightness

This therapy is often considered when chronic soft-tissue injuries fail to improve with rest alone.

Functional Medicine and Lifestyle Medicine

Lifestyle factors significantly influence chronic pain.

Functional medicine often addresses:

Sleep

Poor sleep may increase inflammation, pain sensitivity, fatigue, and recovery time.

Stress

Chronic stress may contribute to muscle tension, hormone imbalance, and nervous system dysregulation.

Movement

Sedentary lifestyles weaken muscles and reduce circulation.

Nutrition

Diet directly affects inflammation and healing.

Hydration

Proper hydration supports muscle and joint health.

Ergonomics

Poor workstation setup and repetitive movement patterns may worsen chronic pain.

Personalized Care Matters

No two patients experience pain the same way.

Functional medicine emphasizes individualized care because:

• Different patients have different inflammatory triggers

• Genetics may influence healing

• Lifestyle habits vary

• Injury history differs

• Stress responses differ

• Nutritional needs differ

At Complete Performance Chiropractic, personalized care plans are designed to match each patient’s condition, goals, and overall health profile. Explore our diverse range of services to see how we build these customized pathways.
