Does anyone here have Arnold Chiari 1 Malformations?

I was just wondering if anyone here has Arnold Chiari 1 Malformation? My Thorasic spine is also enlarged. I also have Multiple sclerosis, and was wondering if anyone is in the same boat I am, and how and what type of medications do they take for it. They say that the Arnold Chiari is caused by a form of spine bifdea, which my father was sprayed with Agent Orange in Vietnam.
Thanks,
