Pain is the hallmark fibromyalgia symptom. You’ll feel it in various muscles and other soft tissues around your body.

The pain can range from a mild achiness to an intense and almost unbearable discomfort. Its severity could dictate how well you cope day to day.

Fibromyalgia appears to stem from an abnormal nervous system response. Your body overreacts to things that shouldn’t normally be painful. And you may feel the pain in more than one area of your body.

However, available research still doesn’t pinpoint an exact cause for fibromyalgia. Research continues to evolve in better understanding this condition and its origin.
