Relapsing-remitting MS is marked by relapses that last at least 24 hours. During a relapse, symptoms get worse. A relapse will be followed by a remission. During a remission, symptoms partly or completely go away.

How long do MS symptoms typically last?

Nearly 9 in 10 people with MS have the common relapsing-remitting form of the disease. In a relapse, an attack (episode) of symptoms occurs. During a relapse, symptoms develop (described below) and may last for days but usually last for 2-6 weeks. They sometimes last for several months.

Can MS symptoms stop?

Over time, symptoms stop coming and going and begin getting steadily worse. The change may happen shortly after MS symptoms appear, or it may take years or decades. Primary-progressive MS: In this type, symptoms gradually get worse without any obvious relapses or remissions.
