DEAR DOCTOR K: I have multiple sclerosis. For me, the most debilitating symptom is fatigue. What can I do to feel more energized?
DEAR READER: Multiple sclerosis (MS) is an illness that affects the brain and spinal cord. Normally, an insulating cover called myelin surrounds nerve cells and helps transmit nerve signals. MS is an autoimmune disease in which the immune system attacks the brain and spinal cord. This causes the myelin sheath to become inflamed or damaged, which disrupts or slows nerve impulses.
