You Did Everything Right and the Pain Stayed. That Is Information.

When pain will not heal after therapy and medication, look at the metabolic terrain. Visceral fat (the deep fat packed around the organs) releases TNF-α and IL-6. These keep tissue inflamed and drive central sensitization. So any local repair works against the setting it sits in.

You went to the appointments. You did the physical therapy. You took the medication you did not want to take, and you took it as prescribed. The pain came back anyway.

The usual explanation at that point is that you must not have tried hard enough. Or that this is simply your life now. Both are wrong, and both are convenient. There is a third explanation that almost nobody checks. The treatment was applied to tissue that was in no biological condition to heal.

What does pain that won’t go away actually mean?

The assembly-line model treats pain as the thing to get rid of. But pain acts much more like a check-engine light. It is the output of a system reporting that something upstream has gone wrong. Silence the light and you have changed nothing about the engine.

This is not a matter of philosophy. It decides what you measure.

How does visceral fat keep pain from healing?

Visceral fat is not idle storage. When metabolism goes wrong, it acts as an active hormone organ. White fat tissue recruits immune cells that release pro-inflammatory cytokines (chemical alarm signals), notably tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6).

When those markers stay high for a long time, they drive neuroinflammation (inflammation of the nervous system) and add to central sensitization — a state in which the nervous system turns up incoming signals. As a result, light touch or ordinary movement starts to register as injury.

The practical result is blunt. If the systemic inflammatory fire is not brought down, the tissue is too inflamed to heal. Any local repair you try is working against the setting it sits in.

Is unexplained pain linked to insulin resistance and leptin?

Fibromyalgia and insulin resistance. Pappolla and colleagues, writing in PLOS ONE in 2019, found that fibromyalgia patients stood apart from control groups by HbA1c, a stand-in marker of insulin resistance, once age was accounted for. A subgroup with pre-diabetic or diabetic HbA1c who were treated with metformin showed marked improvement in widespread pain.

Read that carefully, because the framing matters. The paper is explicitly titled a preliminary report, and it studied 23 patients. It is a hypothesis worth taking seriously, not a settled rate.

Leptin. Leptin is usually called the fullness hormone. In a metabolically disordered body, it also appears to act as a pro-nociceptive signal — one that promotes pain. Younger and colleagues (Journal of Women’s Health, 2016) tracked daily blood leptin against daily self-reported pain. They found leptin predicted roughly 49% of the pain variance. In osteoarthritis, higher leptin in joint fluid is associated with the enzymes that break down cartilage.

The leptin finding rests on a very small study. That daily-tracking arm followed three women.

Against that background, treating the problem with a steroid injection or an opioid alone is, again, silencing the smoke alarm while the house burns.

Does poor sleep slow healing after an injury?

Tissue repair is not a daytime job. Without restorative sleep — roughly seven to eight hours — morning cortisol tends to stay high. A body that stays high in cortisol is catabolic: it favors breakdown over rebuilding. Sleep disruption is also associated with higher systemic CRP and IL-6.

A rehab plan that ignores sleep asks the body to rebuild during the only hours it has been told to tear down.

Can stress and loneliness make pain worse?

Social circumstance is not a soft factor bolted onto the clinical picture. It is a biological input. Money strain and loneliness act as chronic stressors. They keep the system on high alert, which works directly against turning pain signals down. The meta-analysis by Holt-Lunstad and colleagues (Perspectives on Psychological Science, 2015) found social isolation associated with a 29% increase in mortality risk, loneliness 26%, and living alone 32%. It concluded the risk from lacking social relationships exceeds that from obesity.

In our own practice, the overwhelming majority of patients carry at least one significant social determinant of this kind. That is a practice-reported observation from our patient population, not a published statistic, and individual results vary.

How do you treat pain that won’t heal?

We start with a physiological audit, not a procedure schedule. We check markers such as high-sensitivity CRP and LDL particle number, alongside the metabolic picture. That shows what condition the terrain is actually in.

Where it is indicated, metabolic medical management is used to lower the inflammatory load. That includes insulin sensitizers (drugs that help the body use insulin). It comes before or alongside interventional treatment. Do not start, stop, or change any medication without consulting your physician.

There is also a reason to order care this way. Interventional procedures have been reported to give poorer relief in patients with elevated inflammatory markers. If that holds, then fixing the terrain is not an alternative to the procedure. It is what makes the procedure work.

The same terrain decides what an orthobiologic injection can do, because the injectate is made from your own blood. Why the terrain is measured before anything is injected.

Frequently asked questions

Why did my injections stop working?

One possibility few people check is the body’s own biology. Elevated systemic inflammation is associated with poorer response to interventional pain procedures. A local treatment delivered into a persistently inflamed system has to fight that background. The benefit often fades faster.

The Injection Is Made From You. That Is the Whole Problem. goes through it in detail.

What does insulin resistance have to do with pain?

When metabolism goes wrong, it feeds chronic low-grade inflammation. That drives neuroinflammation and central sensitization, a lowered threshold at which the nervous system reports pain. Research has also found high rates of insulin resistance in fibromyalgia patients, though causation is not established.

See The Injection Is Made From You. That Is the Whole Problem.

Does poor sleep really make pain worse?

Yes, and the mechanism is plausible. Too little restorative sleep is associated with elevated cortisol and higher inflammatory markers, including CRP and IL-6. Cortisol-dominant states favor tissue breakdown over repair.

See The Injury You Can Photograph Is the Smaller Half.

Is this saying my pain is caused by my weight?

No. It is saying that metabolic inflammation changes how tissue heals and how the nervous system handles signals. That is not the same thing as body size, and it occurs in people of all builds. The target is the inflammatory state, not appearance.

What tests would tell me if this applies to me?

A metabolic and inflammatory panel is the starting point: high-sensitivity CRP, markers of insulin resistance, and lipid particle measures. These are read alongside your sleep, history and clinical exam. No single value decides it.

Why the terrain is measured before anything is injected is covered in The Injection Is Made From You. That Is the Whole Problem.

What causes pain that doesn’t go away?

Often the tissue is in no biological condition to heal. Visceral fat releases TNF-α and IL-6, which keep tissue inflamed and drive central sensitization. So the nervous system turns up ordinary signals. Poor sleep keeps cortisol high and favors breakdown over repair. Money strain and loneliness keep the system on high alert. Treatment applied on top of that terrain works against the setting it sits in.

Can you ever get rid of chronic pain?

Start by rejecting the two usual explanations: that you did not try hard enough, or that this is simply your life now. Both are wrong. When pain lasts after therapy and medication, the real question is what condition the terrain is in. Bringing the inflammatory load down is not an alternative to treatment. It is what gives treatment a chance to work. Individual results vary.

How do you deal with constant pain?

Stop treating the pain as the only thing to get rid of. It is a check-engine light reporting a problem upstream. Measure the terrain first, with high-sensitivity CRP, LDL particle number and the metabolic picture. Protect seven to eight hours of restorative sleep. Treat social stressors as the biological inputs they are. And, where indicated, lower the inflammatory load before or alongside interventional treatment.

Key takeaways

• Pain is a signal from a system, not a standalone diagnosis.
• Visceral fat drives TNF-α and IL-6, promoting neuroinflammation and central sensitization.
• Inflamed tissue heals poorly, which is one reason good treatments fail.
• Sleep and social stress are biological inputs, not lifestyle side notes.
• Several figures in this area are suggestive rather than settled. That includes the fibromyalgia insulin-resistance and leptin findings.
