Debbie,
You are not the only one that does not understand.

I had my first (and only) major flare in March 2007. I was 50. I have permanent damage from that flare on my left side. That is why I need to use a cane. My rib cage on my left side always feels as though it is being squeezed. Sometimes the stiffness and spasticity is worse, but it is always there. I have other symptoms that come and go. When I was dx, I had 5 lesions. In the next year, I developed three more. I have not had any new lesions in past two years. My neuro thinks that I probably had ms for about ten years. My only symptoms were a partially numb foot and fatigue. Does this mean I am secondary progressive?
