Why Is My Chronic Pain Getting Worse?
Clinically informed by Megan Pennington, BSc, CLT — Integrative Health Practitioner & Certified LEAP Therapist, MP Integrative Health
Chronic pain that worsens over time — despite treatment, despite doing everything right — is one of the most demoralising experiences in chronic illness. It creates the impression that the condition is progressive and uncontrollable. In most cases, the real problem is simpler and more fixable: an ongoing inflammatory driver that has never been identified and removed.
Pain management and pain resolution are fundamentally different goals. Most conventional chronic pain treatment addresses the first — managing the output of an inflammatory process. Almost none of it investigates the input — what is continuously fuelling the inflammation that makes pain worse over time. Understanding this distinction is the starting point for breaking the cycle.
Why chronic pain escalates: the central sensitisation problem
Over time, chronic pain doesn’t just persist — the nervous system changes in response to it. A process called central sensitisation occurs: the spinal cord and brain become increasingly sensitised to pain signals, amplifying them beyond what the original stimulus would produce. The same input generates more pain. The threshold for triggering a pain response drops. Eventually, stimuli that wouldn’t normally cause pain at all become painful.
This explains why chronic pain often feels like it’s escalating even when the original injury or condition hasn’t worsened structurally. It’s not the tissue that’s getting worse — it’s the nervous system’s response to it.
But here’s what’s critical: the threshold at which central sensitisation activates is directly influenced by systemic inflammatory load. More inflammation means a lower pain threshold and a more sensitised nervous system. Less inflammation means the threshold rises and the nervous system becomes less reactive. Reducing the inflammatory input doesn’t just address the source — it fundamentally changes how much pain the nervous system generates from that source.
What drives worsening chronic pain: the three patterns
1. A continuous inflammatory trigger that’s never been removed
The most common — and most fixable — pattern. A food sensitivity creates continuous low-grade immune activation. Inflammatory mediators circulate systemically, affecting joints, muscles, connective tissue, and nerve sensitisation. Pain management strategies (medications, physiotherapy, injections) address the output of this inflammation, but the input continues daily. Pain management has a ceiling when the source is never removed.
In our practice, this pattern is identified when a client’s pain levels show meaningful improvement within days of removing reactive foods through the LEAP Protocol — improvement that pain management approaches never produced, because they were never targeting the right thing.
2. Progressive gut barrier dysfunction
As intestinal permeability worsens — from continued reactive food exposure, stress, dysbiosis, or medication effects — the volume of inflammatory compounds entering systemic circulation increases over time. This progressive increase in the systemic inflammatory load directly amplifies central sensitisation, making pain worse even when the local condition (arthritic joint, fibromyalgia trigger points, inflammatory markers) appears stable.
3. HPA axis dysregulation and cortisol resistance
Chronic pain is inherently stressful. But the relationship runs in both directions: chronic stress worsens pain by dysregulating cortisol, increasing inflammatory cytokine production, and reducing the anti-inflammatory function that cortisol normally provides. When cortisol resistance develops — common in long-standing chronic illness — the immune system loses one of its key regulatory brakes, and inflammatory conditions escalate.
The input/output distinction is the key insight: pain medications, anti-inflammatories, physiotherapy, and injections are output management. They are genuinely useful. But they have a ceiling, and that ceiling is reached when the inflammatory input is never addressed. Identifying and removing food-driven inflammatory triggers through MRT testing lowers the baseline inflammatory load against which all other pain management strategies are working — and allows them to be more effective.
Food sensitivities and joint pain specifically
Joint pain deserves particular attention because it is among the conditions most strongly associated with food-driven inflammation — yet food is almost never investigated in rheumatological care.
When it comes to arthritis and joint pain, food triggers amplify the existing inflammatory response. The same immune dysregulation that attacks joint tissue is often being continuously fuelled by reactive foods that have never been identified. In non-autoimmune joint pain, food-driven systemic inflammation contributes directly to the inflammatory burden making joints more reactive, swollen, and painful.
The delayed nature of food sensitivity reactions — symptoms appearing 2–72 hours after the trigger — means the connection is invisible without testing. Someone eating reactive foods daily will experience continuous joint inflammation and attribute it entirely to their diagnosed condition, never realising that a significant portion of what they experience is driven by dietary immune activation that could be removed.
What reducing the inflammatory input changes
When MRT testing identifies reactive foods and the LEAP Protocol removes them, we consistently see:
- Reduction in baseline pain levels within 1–2 weeks — often more than clients achieved with pain management approaches
- Reduced frequency of pain flares — because the dietary trigger maintaining the baseline inflammatory state is removed
- Improved response to other pain management tools — physiotherapy, medication, and movement therapies work better when the systemic inflammatory load they’re working against is lower
- Reduced joint swelling and stiffness in arthritic conditions — particularly where food-driven immune activation was amplifying the autoimmune response
- Improved sleep — pain disrupts sleep, and reducing pain levels improves the restorative sleep that further supports inflammation resolution
Practical steps alongside investigation
While identifying your specific food triggers through MRT testing is the most impactful step, these support pain management in the interim:
- Reduce ultra-processed foods: refined carbohydrates and seed oils promote inflammatory prostaglandin production. Reducing them lowers the background inflammatory load meaningfully.
- Support gut health: prebiotic-rich foods (leeks, garlic, asparagus, chicory), fermented foods, and adequate fibre diversity reduce the gut dysbiosis contributing to systemic inflammation.
- Address sleep actively: poor sleep increases inflammatory markers and lowers the pain threshold. Prioritising sleep quality — not just duration — is pain management.
- Nervous system regulation: diaphragmatic breathing, gentle movement, and practices that activate the parasympathetic nervous system reduce the cortisol dysregulation that amplifies pain signalling.
- Omega-3 fatty acids: EPA and DHA directly compete with inflammatory arachidonic acid metabolism, reducing prostaglandin and leukotriene production. Meaningful doses (2–3g combined EPA/DHA daily) are required for anti-inflammatory effect.
Worsening chronic pain is not a sign that your condition is inevitably progressive. In the majority of cases we see, it is a sign that an ongoing inflammatory trigger has never been identified and removed. That is not a permanent situation — it is a solvable one.
