What are symptoms of multifocal motor neuropathy (MMN)?

ANSWER

Multifocal motor neuropathy (MMN) is a disease that affects the nerves that control your muscles. You’ll most likely notice your first symptoms in your hands and lower arms. Your muscles may feel weak and cramp up or twitch in a way you can’t control. It may start in specific parts of the arm or hand, like the wrist or finger. Usually the symptoms are more severe on one side of your body. The disease may eventually affect your legs.

MMN isn’t painful, and you’ll still be able to feel with your hands and arms because your sensory nerves are not affected. But your symptoms will slowly get worse as you get older.
