Everyone has their own time-line. People who have PPMS like me walked with canes and I thought "At least I don't." But they stayed with a cane and I went from crutches to rollator to chair. But did a plateau last longer for me? I don't know. Wouldn't matter anyway. They may have bad pain but I really don't. I have physical issues but no cognitive. Maybe my past was better. But it is what it is and asin all life, what you decide to do with what cards you're dealt. I cry sometimes but rarely tell anyone.
