In multiple sclerosis (MS), weakness can come from nerve signal problems. Lack of activity is another factor. Sometimes, you may be less active because of fatigue, stiffness, or a relapse. The longer you are inactive, the weaker your muscles can become.

Questions your doctor might ask:
  • Do you ever feel too weak to do things?
  • Do you feel like you need to put more effort than normal into everyday tasks?
  • Are there specific parts of your body that feel weak, or do you feel weak all over?
Dealing with weakness

With this symptom, the strategies for dealing with it depend on the source of the weakness. Talk to your doctor to determine why the problem is occurring and to create the best plan to help deal with it.
