Primary progressive multiple sclerosis (MS) is a form of MS in
which the disease is progressive from the start. Symptoms such
as muscle weakness, leg dragging, and stiffness become worse,

just a small number of people with MS. In these people, the
illness may be severe from the start with a quick progression of
neurological problems over several months. There are no periods
when symptoms do not occur (remission). Adam Husney, MD - Family
