I started having symptoms about a year and a half ago; in hindsight, there were symptoms earlier. I am having trouble with the quick progression that MS is having. I went from being a functional person, employed, to having trouble with doing basic everyday activities; fatigue, loss of mobility, loss of balance, and a multitude of other symptoms. I have grab bars, motion sensor lights throughout the house, and it's beginning to look like a senior's home. Everything new that happens makes me question if the disease is progressing, and if it is progressing at a quicker-than-normal rate, if there is a normal. How do I know if I need a cane or other assistive devices?
