It can be hard living with fibromyalgia. In addition to persistent pain, the chronic condition often causes symptoms like fatigue, mental fogginess (brain fog), and digestive issues. It may also be difficult to diagnose and treat, which can add to the challenge.
While scientists don’t know exactly what causes fibromyalgia, they’re learning how pieces of the puzzle fit together. And having a better understanding of the disease can lead to faster diagnosis, more effective treatment, and ultimately, a better quality of life.
With that in mind, learn how brain chemicals, sleep patterns, stress—and more—could factor into fibromyalgia, plus newer avenues for treatment.
