Medical professionals claim that Fibromyalgia (FM) is not a progressive illness. However, many people who've lived with FM for 10+ years attest that their FM has indeed progressed.

Just as there is no cure for CFS/ME, there is also no cure for FM. However, some patients may experience long periods of remission where their symptoms improve.

The course of FM may vary and the location and severity of pain can change over time. Symptoms can range from intermittent and fluctuating to persistent.

Quite often FM symptoms appear for no apparent reason. In many cases they appear quite unexpectedly. Other times, triggers of symptom intensification may include excessive activity, inactivity, stress, trauma, repetitive motion, poor sleep, strong emotions and weather changes.
