It's called L'Hermittes. L'Hermittes has different causes such as B-12 defiency, nerve impringment at the c-spine as well as other things.

Your concern is understandable, I think all of us with children worry and wonder.

I would certainly gently encourage your son to see his PCP for some bloodwork and then maybe go from there.

My Dad had MS. He passed away a few years before my diagnosis, so he never had to wonder if or suspect that he "gave" it to me.

My daughter has described symptoms that send chills down my spine. However, I keep telling myself that some COULD be carpal tunnel syndrome, some COULD be many other things. Lots of people are "clumsy" or have balance issues. Still...

My daughter is the least suggestible person I know as far as "maybe I have that", but I'm sure the thought has crossed her mind. We don't talk about the possibility of MS, though I probably have teeth marks on my tongue.
