I was dx last year at the age of 50. I have 6 lesions in my brain and one on my spine. I have muscle stiffness/spasms in my left leg and need to use a cane most of the time when I go out. I also have constant stiffness (ms hug) in left rib cage and back and occasional burning/tingling in my left arm and on the top of my head. So as you can see the number of lesions is not necessarily related to level of disability/problems.
