Different types of Pain

Nociceptive, Neuropathic, and Nociplastic Pain — and Where Massage, Myofascial, and Movement Therapy Fit In

Pain is not a single entity. It is a complex experience shaped by tissues, nerves, and the nervous system’s interpretation of sensory input. Modern pain science recognizes three primary pain mechanisms: nociceptive, neuropathic, and nociplastic pain. While these categories are often discussed separately, most real-world pain presentations involve an interaction between two or more mechanisms.

Understanding which mechanism is dominant helps explain why some pain resolves quickly, why some persists despite treatment, and why the same intervention can help one individual while failing another.

Nociceptive Pain

Pain from Tissue Stress or Injury

Nociceptive pain arises from non-neural tissues such as muscle, fascia, tendon, ligament, joint capsule, bone, skin, or internal organs. These tissues contain specialized sensory receptors called nociceptors, which respond to mechanical overload, inflammation, compression, or chemical irritation.

How It Works

When tissue is stressed beyond its current capacity, injured, or inflamed, nociceptors activate and send signals through the nervous system to the brain. This pain is an appropriate protective response, encouraging rest, unloading, or behavioral change while healing occurs.

Typical Characteristics
• Localized or clearly regional
• Predictable and proportional to movement, load, or pressure
• Reproducible with specific activities
• Improves with rest, tissue healing, or load modification
• Often described as aching, sore, throbbing, or sharp

Common Examples
• Muscle strain or tear
• Tendon overload or tendinopathy
• Joint inflammation or osteoarthritis
• Acute ligament injury
• Post-surgical pain
• Visceral pain from internal organs (a nociceptive subtype)

Where Massage & Myofascial Therapy Fit

Massage and myofascial therapy are particularly effective for nociceptive pain because they directly address the tissues generating the input. They can:
• reduce excessive muscle tone
• improve fascial glide and hydration
• decrease localized inflammation and ischemia
• improve circulation and lymphatic flow
• restore more normal tissue load-sharing

By improving tissue quality and reducing mechanical irritation, nociceptive input to the nervous system decreases.

Where Movement Therapy Fits

Movement therapy:
• restores appropriate loading patterns
• rebuilds tissue tolerance
• improves coordination and force distribution

Without progressive, well-designed movement, tissues often remain vulnerable to re-injury—even if manual therapy initially reduces pain.

Neuropathic Pain

Pain from Injury or Disease of the Nervous System

Neuropathic pain originates from damage or dysfunction within the nervous system itself, rather than from injured muscles or joints. The source of pain may be a peripheral nerve, nerve root, spinal cord, or the brain.

How It Works

When nerves are compressed, inflamed, traumatized, or degenerate, they can generate abnormal signals. These signals may fire spontaneously, misfire in response to normal input, or amplify sensations that should not be painful.

Typical Characteristics
• Burning, electric, stabbing, or shooting sensations
• Tingling, pins-and-needles, or numbness
• Often follows a nerve distribution
• May occur without clear mechanical provocation
• Frequently accompanied by sensory changes or weakness

Common Examples
• Radiculopathy from disc herniation
• Peripheral neuropathy
• Nerve entrapment syndromes
• Spinal cord injury–related pain

Where Massage & Myofascial Therapy Fit

Manual therapy does not repair damaged nerves, but it can play an important supportive role by:
• reducing mechanical compression around nerves
• improving mobility of neural interfaces
• calming surrounding muscle guarding
• reducing sympathetic nervous system tone

Gentle, indirect techniques are often more effective than aggressive work in neuropathic presentations.

Where Movement Therapy Fits

Movement therapy focuses on:
• restoring neural glide and tolerance
• improving coordination without provoking symptoms
• avoiding positions or loads that irritate neural tissue

Graded, pain-informed movement helps normalize nerve signaling without reinforcing threat.

Nociplastic Pain

Pain from Altered Nervous System Processing

Nociplastic pain occurs when pain is generated by changes in how the nervous system processes sensory input, without clear evidence of ongoing tissue damage or nerve injury. This reflects a state of heightened pain sensitivity, often involving central sensitization.

How It Works

The nervous system becomes overly responsive. Signals that would normally be non-painful—or only mildly uncomfortable—are amplified. The “volume knob” on pain processing is turned up, even in the absence of tissue threat.

Typical Characteristics
• Widespread or poorly localized pain
• Disproportionate to imaging or exam findings
• Persistent or fluctuating symptoms
• Often associated with fatigue, sleep disturbance, stress sensitivity, or cognitive fog
• Symptoms may shift over time

Common Examples
• Fibromyalgia
• Chronic widespread pain
• Persistent pain after tissue healing
• Some chronic neck or low back pain presentations

Where Massage & Myofascial Therapy Fit

In nociplastic pain, manual therapy works primarily through neurological rather than structural mechanisms. It helps by:
• providing non-threatening sensory input
• improving interoception and body awareness
• activating parasympathetic (rest-and-digest) responses
• reducing global muscle guarding

The goal is not “fixing tissue,” but changing how the nervous system interprets sensory input.

Where Movement Therapy Fits

Movement therapy is central in nociplastic pain management. Effective strategies:
• emphasize safety and predictability
• use slow, graded exposure
• prioritize coordination and confidence over strength
• rebuild trust in movement

Movement becomes a way to retrain the nervous system—not just the body.

Mixed Pain: Where Most Cases Live

Most persistent pain presentations involve overlapping mechanisms, such as:
• nociceptive tissue changes
• nervous system sensitization
• altered motor patterns

This is why combining approaches is often necessary.

Massage and myofascial therapy:
• improve tissue quality
• reduce excessive sensory “noise”
• create a window of opportunity for change

Movement therapy:
• consolidates those changes
• re-educates motor control
• improves long-term resilience and prevents recurrence

Neither works as well in isolation.

Why Pain Sometimes Returns After Bodywork

If pain improves briefly after massage but returns quickly, it often indicates:
• a dominant neurological driver (laterality, sensitization, poor motor organization)
• insufficient movement integration
• unresolved load, posture, or training factors

Manual therapy prepares the system.
Movement therapy teaches the system how to use that change.

Final Takeaway
• Nociceptive pain responds best to tissue-focused care plus appropriate loading.
• Neuropathic pain requires neural protection, decompression, and graded exposure.
• Nociplastic pain requires nervous system regulation and confidence-building movement.

Massage and myofascial therapy change the input.
Movement therapy changes the organization.

Lasting change happens when both are addressed together.

Why is Vitamin E can be lacking this time of year and more so by the thoroughbred

The Effects on Fascia, Muscle, and Nerves: Why Vitamin E Deficiency Is More Common This Time of Year and Why It’s More Common in TBs

Vitamin E is an antioxidant essential for:
• muscle health
• nervous system function
• immune support
• recovery and performance
• preventing muscle soreness (tying up, fasciculations, stiffness)

Horses cannot synthesize vitamin E. They get it only from fresh forage—especially green, growing pasture.

Before exploring the seasonal causes, it’s important to understand how low vitamin E affects the body’s most sensitive systems:

The Effects on Fascia, Muscle, and Nerves

Effects on Muscle

Vitamin E deficiency can lead to:
• increased muscle cell damage from oxidative stress
• slower repair of micro-tears
• reduced ability to clear metabolic waste
• greater post-exercise soreness
• stiffness, cramping, or tying up (especially in TBs)
• difficulty developing or maintaining topline
• delayed recovery after normal work

Muscles fatigue faster, repair slower, and hurt more when vitamin E is low.

Effects on Fascia

The fascial system depends heavily on antioxidants for glide, hydration, and elasticity. Low vitamin E contributes to:
• reduced fascial glide
• thickened or “sticky” fascial planes
• increased whole-body stiffness
• compensatory tension patterns
• slower response to bodywork
• decreased force transmission through myofascial lines

Fascia becomes less elastic and more reactive, creating the tight, rigid feeling many owners notice.

Effects on the Nervous System

Vitamin E is crucial for nerve health—especially long peripheral nerves in the limbs, back, and hindquarters.

Deficiency may cause:
• increased nerve irritability
• muscle fasciculations (twitching)
• poor proprioception
• stumbling or uncoordinated movement
• hypersensitivity to pressure or touch
• vague neurologic signs that mimic weakness
• difficulty maintaining coordination under saddle

Even mild deficiency can make a horse feel shaky, twitchy, weak, or unbalanced.

Horses Without Pasture Access (Year-Round Risk)

Some horses receive little or no access to fresh pasture at any time of year, including:
• metabolic horses on dry lots
• rehab horses on restricted turnout
• horses in desert or arid regions
• horses boarded in facilities with limited grazing
• horses kept in sand pens or small paddocks

These horses are at constant risk of low vitamin E and often require year-round supplementation, not just seasonal support.

Why Vitamin E Deficiency Becomes More Common This Time of Year

1. Pasture Quality Drops Dramatically

In late fall–winter–early spring:
• grass goes dormant
• green content drops
• vitamin E content plunges
• horses graze less
• many move to dry lots or sacrifice paddocks

Fresh grass is the #1 natural source of vitamin E. When it disappears, intake drops sharply.

2. Hay Contains Very Little Vitamin E

Even high-quality hay loses up to 80% of vitamin E within:
• 6–8 weeks after cutting
• and continues degrading during storage

By winter or early spring, most hay contains:

👉 virtually no vitamin E

Even alfalfa loses its vitamin E during curing.

3. Horses Often Work More or Differently in Winter

Changing workload can increase oxidative stress, raising the horse’s vitamin E requirement:
• exercise
• training changes
• trailering
• indoor arena footing
• cold-weather stiffness

This creates a “higher need, lower intake” imbalance.

4. Confinement + Less Movement = Higher Oxidative Stress

More time in:
• stalls
• dry lots
• small paddocks

…reduces muscle circulation and increases oxidative load, raising antioxidant needs.

5. Not All Feeds Provide Enough Vitamin E

Many horses rely on:
• ration balancers
• basic grain mixes
• senior feeds

Even fortified feeds often fail to meet vitamin E needs unless the horse eats the full recommended serving.

Most horses need 1,000–2,000 IU/day, while performance horses may need 2,000–5,000 IU/day.

Why Thoroughbreds May Be More Prone to Vitamin E Deficiency

This is something many professionals observe, and several valid reasons explain why.

1. Higher Metabolic Rate

Thoroughbreds have:
• higher metabolic demand
• faster oxidative turnover
• naturally stronger stress responses

They burn through antioxidants—including vitamin E—much faster.

2. More Prone to Muscle Disorders

TBs are more susceptible to:
• tying up (RER)
• muscle soreness
• fasciculations
• exercise intolerance

Vitamin E deficiency increases the severity and frequency of these issues.

Why Thoroughbreds Are More Prone to Muscle Disorders

Key contributing factors include:

• Natural Predisposition to RER

Many TBs have a genetic tendency toward Recurrent Exertional Rhabdomyolysis (RER), where:
• muscle cells mismanage calcium
• contractions last too long
• muscles cramp, stiffen, or “tie up”

• Fast-Twitch–Dominant Muscle Fibers

TBs are built for:
• speed
• power
• rapid acceleration

Meaning:
• higher heat production
• greater oxidative stress
• elevated vitamin E needs

• High-Strung, Reactive Nervous System

Thoroughbreds often have:
• a naturally “ready for action” nervous system
• higher sympathetic tone
• elevated baseline muscle tension

This makes their muscles:
• more contracted
• more reactive to stress
• more prone to spasms and soreness

• Common TB Management Patterns

Many TBs experience:
• limited turnout
• increased stall time
• high-starch diets
• inconsistent exercise
• environmental stress

All raise the risk of:
• muscle tightness
• cramping
• tying up
• vitamin E depletion

3. Many TBs Are Coming Off the Track

Ex-racers often have:
• long periods stalled
• hay-based diets
• limited turnout
• high muscular stress
• nutritional gaps from racing environments

They frequently begin their post-track life already low in vitamin E.

4. Stress Sensitivity

TBs tend to be:
• sensitive
• high-alert
• reactive

Chronic stress increases oxidative load → increasing vitamin E requirements.

5. Thin Body Type = Less Antioxidant Reserve

Thoroughbreds typically have:
• lower natural fat stores
• fewer fat-soluble nutrient reserves
• faster depletion of vitamin E

This makes deficiency symptoms appear sooner.

Signs of Low Vitamin E (Common in Winter + TBs)
• muscle twitching
• topline loss despite adequate feed
• poor stamina
• slow recovery after exercise
• weakness or stumbling
• vague hind-end issues
• difficulty holding chiropractic/bodywork results
• nerve hypersensitivity
• lowered immune resilience

TBs often show subtle early signs.

Supplement Tip: Not All Vitamin E Forms Are Equal

Vitamin E supplements vary widely in absorption. In horses:
• Natural d-alpha-tocopherol is better absorbed than synthetic dl-alpha-tocopherol
• Water-dispersible (micellized) forms are ideal for horses on low-fat diets or those showing deficiency
• Powdered synthetic forms may not significantly raise blood levels in some horses

For horses showing symptoms, a high-quality natural, water-dispersible form is often the most effective.

Important Selenium Caution

Vitamin E and selenium are often paired, but:
• many feeds and balancers already contain selenium
• too much selenium can be toxic
• avoid stacking multiple E/Se products without checking totals

Always review total selenium intake with a veterinarian before adding selenium-containing supplements.

When to Involve Your Veterinarian

Consider veterinary testing if you notice:
• persistent muscle twitching
• unexplained weakness, stumbling, or poor coordination
• progressive topline loss
• vague neurologic signs
• chronic soreness or delayed recovery
• sudden behavior changes that feel “neurologic”

A simple serum vitamin E test can confirm deficiency and guide dosage.

Other High-Risk Horses

Beyond Thoroughbreds, vitamin E deficiency may appear sooner in:
• older horses
• horses in intense work
• horses with chronic pain or compensation patterns
• metabolic horses kept off grass
• horses recovering from illness or injury

These horses may benefit from proactive supplementation.

The Bottom Line

Vitamin E deficiency becomes more common this time of year because:
• pasture disappears
• hay contains almost no vitamin E
• work + confinement increase antioxidant demand

Thoroughbreds are more prone to deficiency because of:
• higher metabolic demand
• heightened stress reactivity
• muscle sensitivity and RER tendencies
• feeding and turnout patterns
• lower nutrient reserve capacity
