It has been reported that some patients have been misdiagnosed with Fibromyalgia Syndrome, when in fact the correct diagnosis in their specific case was Chronic Fatigue Syndrome.
Chronic fatigue syndrome also known as myalgic encephalomyelitis is a condition define by extreme fatigue that lasts for over six months and isn’t linked to any other medical condition. Fatigue must worsen with physical or mental activity and does not improve with rest. Symptoms include sleep that does not improve fatigue, difficulties with memory, concentration and focus, dizziness that worsens with moving from lying down to sitting to standing, sore throat, headaches, enlarged lymph nodes in neck or armpits, and unexplained muscle or joint pain. Chronical fatigue syndrome can be misdiagnosed as fibromyalgia, neurasthenia, chemical sensitivities, chronic mononucleosis, hypothyroidism, sleep apnoea, narcolepsy, depression, eating disorders, cancers, and multiple sclerosis.
