CIDP has a variety of signs and symptoms that differ from person to person

The most common symptoms of CIDP are weakness, numbness, and tingling in the legs, arms, fingers, and hands. Other symptoms include fatigue, pain, balance issues, and impairment of your ability to walk. Some people have described feeling as if there were an electrical storm in their arms or legs.1,2

Symptoms usually occur on both sides of the body at the same time. But sometimes only one side is involved. You may experience symptoms in your head, arms, fingers and hands, legs, and toes and feet. Symptoms of CIDP can be mild, moderate, or severe and change in severity over time.1,3

Guillain-Barré syndrome is a disorder in which the body's immune system attacks part of the peripheral nervous system.5

Amyotrophic lateral sclerosis is a progressive disease that affects nerve cells in the brain and the spinal cord, causing weakness in the neck, arms, and legs, and in muscles controlling speech, swallowing, and breathing.7

Multiple sclerosis is a chronic, typically progressive disease that affects the brain and spinal cord, causing symptoms like numbness, impairment of speech and muscular coordination, concentration problems, urinary urgency or incontinence, and blurred vision.6

CIDP can be misdiagnosed due to similar symptoms associated with other conditions like GBS, MS, or ALS.
