Why does fibromyalgia make my whole body hurt even when nothing seems to be wrong in scans?
+

That’s because fibromyalgia does not usually show up in X-rays or MRIs. The pain is not really caused by damage to your tissues – it is caused by how your brain and spinal cord processes pain signals. This is called central sensitization, and it can make even normal sensations feel quite intense and painful. The nervous system is basically on constant alert, even when there is no real threat. 

Why is brain fog such a common part of fibromyalgia?
+

Brain fog happens because your brain is constantly flooded with pain signals, inflammation, and stress chemicals. It becomes very hard to concentrate, feel mentally clear, or remember things. Triggers such as EMFs, mold, toxins, and poor sleep only makes it worse. 

What causes fibromyalgia to start in the first place?
+

There is not just one cause. For many, fibromyalgia begins after long-term stress, viral infections, gut imbalances, infections, or hormonal changes. Some individuals have a genetic tendency, but how your nervous system and brain react to life stressors plays the biggest role. Early life stress or trauma - also called adverse childhood experiences - can make you more sensitive to pain later in life.

What is central sensitization and how does it relate to fibromyalgia?
+

Central sensitization is when your nervous system becomes hypersensitive, so even light touch or small stressors can feel painful or overwhelming. It’s one of the main explanations for why fibromyalgia causes such widespread, unexplained pain. iThrive helps calming these overactive signals naturally.

Why don’t medications always help fibromyalgia symptoms?
+

Medications mostly focus on minimizing pain or improving sleep, but they do not address the root cause – which is a dysregulated nervous system, trauma patterns stuck in the body. That’s why many people don’t find long-term relief solely from pills.  

A root-cause approach like iThrive’s Functional Coaching + Essentials Protocol helps you retrain your brain and body toward healing.
