• moderate to severe fatigue
• heightened sensitivity of the skin or tingling of the skin (needle-like)
• achiness in the muscle tissues, prolonged muscle spasms, weakness in the limbs, and nerve pain

• cognitive dysfunction - known as "brain fog" or "fibrofog" (impaired concentration and short-term memory consolidation, impaired speed of performance, inability to multi-task, and cognitive overload. Many experts suspect that "brain fog" is directly related to the sleep disturbances experienced by sufferers of fibromyalgia.
