Myalgic

Myalgic Encephalomyelitis (ME), also known as Chronic Fatigue Syndrome (CFS), is a complex, chronic medical condition characterized by severe fatigue and other symptoms. These symptoms are worsened by physical or mental activity, but do not improve with rest.

Symptoms

The primary symptom of ME/CFS is fatigue, which is not improved by rest and is worsened by physical or mental activity. Other symptoms can include:

• Cognitive difficulties such as problems with memory, concentration, and thinking
• Pain in the muscles or joints
• Headaches
• Unrefreshing sleep
• Post-exertional malaise (PEM), a worsening of symptoms after physical or mental activity
• Orthostatic intolerance, a condition in which symptoms worsen when a person stands or sits upright

Causes

The exact cause of ME/CFS is unknown, but it may be related to a combination of factors. These can include:

• Viral infections
• Immune system problems
• Hormonal imbalances
• Stress

Diagnosis

Diagnosis of ME/CFS can be difficult, as there is no specific test for the condition. Instead, doctors must rule out other conditions that can cause similar symptoms. The Centers for Disease Control and Prevention (CDC) has criteria for diagnosing ME/CFS, which includes having four or more of the following symptoms for six months or more:

• Post-exertional malaise
• Unrefreshing sleep
• Significant impairment of short-term memory or concentration
• Muscle pain
• Pain in the joints without swelling or redness
• Headaches of a new type, pattern, or severity
• Frequent or recurring sore throat
• Tender lymph nodes in the neck or armpit

Treatment

There is currently no cure for ME/CFS, but treatment can help manage symptoms. This can include:

• Cognitive behavioral therapy (CBT)
• Graded exercise therapy (GET)
• Medications to manage pain, sleep disorders, and other symptoms
• Lifestyle changes, such as pacing activities and managing stress
