Can MS Symptoms Swap Sides?

Hi All

I'm still awaiting diagnosis. My brain MRI is on Monday ~ Finally!

But I was wondering if it was possible for MS symptoms to swap sides?

The reason I am asking is, for the longest time I had a 'numb' band around the top of my right calf, just below my knee. Over the past couple of days it seemed to settle down.

When I was on my feet last night doing some housework, and on them again this morning when out shopping, I'm having the same feeling, in the same spot, but on the left side now ~ my right side still feels fine though.

Any input would be greatly appreciated.

Thanks
MM
