Anti-Inflammatory Drugs May Worsen Tissue Perfusion and increase pain

THE CARCO STRESS MODEL: Carbon Monoxide Exposure → Peroxynitrite Formation in Capillaries → Fibrin Amyloid Formation → Microvascular Obstruction → Reduced Mitochondrial Oxygen Availability → Aerobic Energy Production Failure → Systemic Dysfunction

​Carbon monoxide exposure causes the formation of fibrin amyloids, which physically restrict oxygen delivery to tissues. This page explains why anti-inflammatory drugs fail to resolve symptoms when the true underlying problem is this structural oxygen deprivation, rather than classical inflammation.

Why These Drugs Are Commonly Prescribed

​People experiencing symptoms of fibrin amyloid accumulation are often diagnosed as having chronic low-grade inflammation. They are frequently prescribed anti-inflammatory medications, particularly pain relievers. This happens even when standard inflammatory markers remain normal in blood tests.

How Anti-Inflammatories Can Affect the Body

Some anti-inflammatory drugs may affect:

• Blood flow regulation
• Vascular signaling
• Oxidative balance
• Mitochondrial function
• Oxygen-related physiology

If oxygen delivery and cellular energy production are already impaired, additional stress on these systems can worsen symptoms.

Functional Decline and Escalating Symptoms

Deep, heavy, structural pain

The pain that follows this microvascular collapse is true ischemic pain. It is qualitatively different from inflammatory pain because entirely different neurological receptor pathways are activated in the tissue.

It is perceived by the patient as deep, heavy, and structural — not simply because the pain is severe, but because the actual physiological event producing that pain is severe.

Common Symptoms That May Worse

• Increased fatigue
• Worse exercise intolerance
• Muscles fatigue faster
• Legs feel unusually heavy or unstable
• Pain increases during physical load
• Recovery after activity becomes slower
• Tissues may feel weak, “empty,” or unable to tolerate normal load
• Unstable joints – feel they gonna collapse

COX-2 inhibitors stop blood flow

COX-2 inhibitors block the COX-2 enzyme, which stops the production of prostacyclin in blood vessel linings. This causes small blood vessels to tighten, stops blood flow, and starves cells of oxygen – worsening fatigue, exercise intolerance, and tissue stress—especially in people who already have issues with oxygen delivery or cellular energy.

This imbalance raises the risk of heart attacks, strokes, and high blood pressure. 

MICROCIRCULATION SHUTS DOWN COMPLETELY

Under normal conditions, a delicate balance keeps the smallest blood vessels open. COX-2 inhibitors disrupt this balance by blocking prostacyclin production in the blood vessel lining.

Simultaneously, the opposing mechanism — thromboxane, which narrows vessels and promotes clotting — continues operating without resistance. When the protective prostacyclin signal is eliminated, the vascular balance collapses and microcirculation shuts down completely.

Tissues With Zero Oxygen Reserve

Certain dense structural tissues are uniquely vulnerable to this sudden drop in perfusion. Bone, cartilage, and joint capsules possess no native oxygen reserve. They depend on a continuous microvascular supply to function.

When that microvascular supply is cut by vasoconstriction, these specialized cells cannot produce ATP, cellular function begins to fail.

Microvascular collapse causes Ischemic Pain

An Ischemia Crisis, Not Inflammation

When a patient experiences agony in these areas after vascular shutdown, the underlying process is often completely misunderstood. This is not classical inflammation, nor is it simple nerve sensitivity. This is an oxygen and energy emergency at the cellular level — the exact same fundamental crisis that occurs in cardiac muscle during a myocardial infarction.
