Chronic Fatigue Syndrome (CFS) and Fibromyalgia (FM) can be difficult to diagnose, but having a Chronic Fatigue Syndrome Fibromyalgia Symptom Checklist is the first step in understanding if you or someone you know may have these conditions. This checklist provides individuals with a list of common symptoms associated with both CFS and FM, allowing them to assess their symptoms so that they can seek the appropriate medical attention if necessary.
