Re: Worried
No, not initially and only after the disease has progressed significantly i.e. failure of mobility.
Now please stop asking questions as you have been requested to. This site is an incredibly unhealthy place for hypochondriacs. Spending hour upon hour, from morning until night, on a site that's for terminally ill members is more telling about your psychological state than your physical state. Sorry to be blunt, but it's true.
Please move on for good. Take good care and good bye.
