Hi Melissa

The spot on the right side of your brain might be a sign of a small stroke. The asymmetry (right side brain, left side physical issues) is consistent with this. Your neurologist should be able to talk with you about this.

If it turns out that a small stroke is a possibility then getting your GP to check you out for cardiovascular disease risk factors (high blood pressure, high LDL cholesterol levels, etc) would be a good idea.
