Fatigue

Fatigue in ME/CFS typically has the following components:

• - feeling flu-like, especially in the early days of the illness.
• - restlessness or feeling 'wired but tired'.
• - low energy or a lack of physical energy to start or finish activities of daily living and the sensation of being 'physically drained'.
• - cognitive fatigue that worsens existing difficulties.
• - rapid loss of muscle strength or stamina after starting an activity, causing for example, sudden weakness, clumsiness, lack of coordination, and being unable to repeat physical effort consistently.
