-MS does not cause pain
-Neuropathic and muscle pain in MS are real, but pain from the disease is overreported
-Pain from MS can be debilitating, but it is a variable symptom affecting a minority of patients
-MS routinely causes minor and major pains, and is experienced by the majority of patients
-Pain in MS still is vastly underreported and is a significant underlying symptom of the disease
-None of the above
