Since you're managing fibromyalgia, it's worth focusing on the fatigue that comes with it, as the two experiences can feel very similar and are often talked about together in the fibromyalgia community.

Fibromyalgia-related fatigue has several known contributors:

- Brain changes – The part of the brain that processes sensory information (the thalamus) may become overloaded by constant pain signals, leading to less gray matter and more fatigue
- Poor sleep – Many people with fibromyalgia don't reach deep, restorative sleep, leaving them exhausted even after a full night's rest
- Muscle inefficiency – Muscles in fibromyalgia require more energy than usual and don't always relax properly between use
- Melatonin disruption – Fibromyalgia can interfere with the body's natural sleep-wake chemical, making you feel sleepy at the wrong times
- Immune system activity – Increased immune cell activation in the central nervous system is also linked to fatigue

One MyFibroTeam member described it as feeling "like an old, damp, worn-out cloth, with no energy and no strength."

If your fatigue feels new or worse than usual, it's a good idea to check in with your care team to rule out other contributing factors.
