Fatigue is not simply feeling tired all day. Scientists are still trying to understand the complexities of MS fatigue, but they have discovered that there are different types of fatigue. People can, and do, suffer from both kinds simultaneously.
- Primary fatigue

- Secondary fatigue
- Caused by other factors related to multiple sclerosis including medication side effects and sleep problems
