Medically speaking, fatigue is not the same thing as tiredness. Tiredness happens to everyone -- it is an expected feeling after certain activities or at the end of the day. Usually you know why you are tired and a good night's sleep solves the problem.
Fatigue is a daily lack of energy; unusual or excessive whole-body tiredness not relieved by sleep. It can be acute (lasting a month or less) or chronic (lasting from one to six months or longer). Fatigue can prevent a person from functioning normally and affects a person's quality of life.
If you have progressive relapsing multiple sclerosis (PRMS), your condition will get steadily worse from the very beginning.
But you also will experience distinct relapses, with or without full recovery. Between relapses, the disease continues to gradually worsen.
PRMS is the least common type of multiple sclerosis. It affects about 5% of all people with MS.
According to the National Multiple Sclerosis Society, 80% of people with MS have fatigue. MS-related fatigue tends to get worse as the day goes on, is often aggravated by heat and humidity, and comes on more easily and suddenly than normal fatigue.
What Can I Do About MS-Related Fatigue?
The best way to combat fatigue related to your MS is to treat the underlying medical cause. Unfortunately, the exact cause of MS-related fatigue is often unknown, or there may be multiple causes. However, there are steps you can take that may help to control fatigue. Here are some tips:
1. Assess your personal situation.
Evaluate your level of energy. Think of your personal energy stores as a "bank." Deposits and withdrawals have to be made over the course of the day or the week to balance energy conservation, restoration, and expenditure. Keep a diary for one week to identify the time of day when you are either most fatigued or have the most energy. Note what you think may be contributing factors.
Be alert to your personal warning signs of fatigue. Fatigue warning signs may include tired eyes, tired legs, whole-body tiredness, stiff shoulders, decreased energy or a lack of energy, inability to concentrate, weakness or malaise, boredom or lack of motivation, sleepiness, increased irritability, nervousness, anxiety, or impatience.
