My neurologist thinks I may have MS what would be the chance of passing it to a child if I do have it?

MS not genetic. Ms is not passed to children. It is thought, though not proven, that MS is caused by a virus. Regardless of cause, your children are not at risk.
Probably none, but.. I have never seen a patient with ms who had a parent or parents with ms. Statistically, a person who has one or more family members with ms has a slightly higher risk of developing ms. However, the risk goes up from extremely low to very low.
Very remote. If you really did have MS, the susceptibility of your child would be about 3-4% at most.
