My Dad had MS. He was never clinically diagnosed but I came to the conclusion after I was dx and I looked back on all his sx. He had so many things going on with his health that MS was never seriously looked at.
My cousin has MS. My Dad's brothers daughter.
That's the only ones I know about. I know of nobody in DH's family that has/had it.
I know how you feel, Lynn. My oldest son has had some of the classic MS sx in the past and it worries me greatly. He's mentioned how it feels like something wet on his leg but nothing is there.
He's also mentioned issues with his eyes. I know that could be any number of things but, as a Mother, I tend to think of the worst first.
I pray that none of our children ever has to deal with this disease. I'd rather mine get worse than for them to ever have to be burdened with it.
