It is often difficult to get sympathy or understanding for this type of problem, even though fatigue can be the most debilitating part of having MS.

While everyone experiences “being tired” occasionally, the fatigue associated with MS has certain characteristics, including:
  • Occurring daily
  • May be present in the morning, even after a good night’s sleep
  • Worsens as the day progresses
  • Aggravated by heat and humidity
  • Comes on suddenly
  • More severe than normal fatigue and more likely to interfere with daily life
For some people, there are additional related symptoms, including:
  • Feeling of heaviness in the arms and legs
  • Worsening of other symptoms, such as problems with balance or vision, or slurring speech
  • Difficulty concentrating
  • Vertigo or dizziness
  • Headaches
  • Feeling ill, like you have the flu
