76
What are the sources of chronic pain
* Nervous System Sources (NMDA Receptor Mechanism): Located in spinal cord synapses, Becomes active with constant glutamate bombardment, Increases calcium binding, Activates surrounding glial cells
* Neurological Changes: Pain pathways modify and amplify over time, Potential for developing persistent pain syndromes, Nervous system becomes "wound up"
* Immune System Interactions: Disrupts normal inflammatory homeostasis; Can lead to: Hyperimmune responses, Autoimmune conditions, Reduced infectious disease response
* Fascial System's Role: Largest organ system in body, Can become "sticky" with inactivity, Carries body awareness, Actively contracts and modulates body mechanics
* Aging-Related Sources: Multiple pain sources, Increased susceptibility to "inflammaging", Aging immune system complications
77
Understand pain pathway amplification that accompanies chronic pain
* Pain Pathway Amplification Mechanisms (NMDA Receptor Mechanism): Located in spinal cord synapses, Normally plugged with magnesium, Becomes activated with constant glutamate bombardment
* Amplification Process : Tissue damage triggers constant nerve signal bombardment, NMDA receptor loses its magnesium plug, Increases calcium binding leads to, Presynaptic neuron becomes more active, Postsynaptic neuron becomes more active,Activates surrounding glial cells
* Example Illustration: Dr. Wright uses a toe-stubbing scenario to explain amplification the Initial injury causes pain Over hours, pain becomes more intense and throbbing Continuous stimulation "winds up" pain sensation
* Consequences of Amplification: Can transform from acute to chronic pain syndrome, Modifies pain pathways in complex ways, Involves multiple body systems (nervous, immune, fascial)
78
Understand immune imbalance that accompanies chronic pain
79
Understand kinesthetic/mobility changes that accompanies chronic pain
* Normal Immune Homeostasis: Typically maintains a balance of pro-inflammatory and anti-inflammatory mediators; Body expects inflammation to: Kick in during injury/illness & Resolve and return to normal state
* Chronic Pain Immune Disruption: Ongoing pain source makes it challenging to maintain immune balance; Potential consequences include: Difficulty balancing pro-inflammatory and anti-inflammatory effects & Complications with inflammation management
* Aging and Immune Imbalance: Dr. Wright introduces the term "inflammaging"; Elderly patients experience: Intrinsic immune system imbalance, Reduced immune system effectiveness, & Multiple pain sources compounding immune challenges
* Specific Immune Imbalance Outcomes: Hyperimmune responses, Potential autoimmune conditions, & Reduced infectious disease response
80
Understand fascia & soft tissue strain patterns that accompanies chronic pain
* Fascia Defined: Largest organ system in the body, White connective tissue under the skin, Connects muscles, tendons, bones, and organs, & Creates interstitial fluid space
* Fascia Functions: Body awareness, Immunity, Fluid balance, Connecting tissues, Surrounds all organs and vessels
* Soft Tissue Strain Patterns: Can become "sticky" with inactivity, Actively contracts and modulates body mechanics, Carries body awareness, Interrelates with muscle groups
* Pain Compensation Mechanisms: Injury causes changes in movement patterns, Compensation leads to additional soft tissue problems, Altered mobility changes body kinesthetics
* Fascial Characteristics in Chronic Pain: Becomes stiff with inflammation, Reduces tissue sliding and gliding, Can create stress across joints, Potentially leads to disc/joint stress
81
Describe therapy for chronic pain involving medications & supplements
* Opioids: Limited use in chronic pain, Not recommended long-term, Neuroinflammatory effects, Poorly absorbed in dogs and cats
* Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Effective for both acute and chronic pain, Potential disease-modifying effects, Require regular blood work monitoring; Examples: Carprofen, Meloxicam, Galliprant (EP4 receptor antagonist)
* Gabapentin: De-amplifies nervous system, Can cause sedation
* Pregabalin: Similar to Gabapentin, Fewer side effects, Twice-daily dosing
* NMDA Antagonists: Ketamine, Amantadine, Help de-amplify pain sensing system, Neuroprotective properties
* Omega-3 fatty acids: Joint support supplements, Antioxidants, Adaquin, Collagen-based supplements
* Injection Therapies: Nerve growth factor inhibitors (Librela, Solensia); Joint injections: Steroids, Hyaluronic acid, Biological treatments, Platelet-rich plasma, Stem cells
* Supplement Selection Criteria: Scientifically validated products, Check EPA/DHA concentrations, Prefer sustainably sourced options
* Recommended Supplement Brands: Nordic Naturals, Look for specific EPA/DHA milligram concentrations
* Key Therapeutic Approach: Holistic, integrative treatment, Combine pharmacological and non-pharmacological interventions, Individualized treatment plans, Regular monitoring
82
Describe therapy for chronic pain involving Diet, nutrition, & weight
* Weight Management: Highly correlated with pain management, Obesity is pro-inflammatory, Weight reduction is analgesic, Can have greater impact than anti-inflammatory medications, Veterinary studies show weight loss can improve pain more effectively than NSAIDs
* Food Choices: Focus on less inflammatory foods, Debate between fresh vs. dried foods, Consider foods with lower inflammatory potential
* Nutritional Strategies: Choose foods that reduce inflammatory state, Improve overall metabolic outlook, Support patient comfort
* Supplement Recommendations: Omega-3 fatty acids, Joint support supplements, Antioxidants, Careful selection of scientifically validated products
