What is chronic fatigue syndrome?
Chronic fatigue syndrome, or myalgic encephalomyelitis (ME), causes a chronic, unrelenting exhaustion that worsens when you engage in any activity that requires mental or physical energy. Many patients with chronic fatigue syndrome develop extreme exhaustion that lasts longer than 24 hours after physical or mental exertion.
The fatigue you develop also doesn’t improve when you get rest. It’s such an extreme fatigue that it can be impossible to complete simple tasks such as getting dressed or cooking dinner.
In addition to fatigue, you may experience symptoms such as muscle and joint pain, difficulty concentrating, problems with your memory, and headaches. Your symptoms can last for weeks, months, or years.
