Common early warning signs of multiple sclerosis include strange sensations, difficulty controlling extremities when warm, vision problems, unexplained fatigue and problems walking, says WebMD. Other possible signs include depression, vertigo, confusion, incontinence and pain, depending on what part of the nervous system is affected. These symptoms can be subtle and appear widely spaced from one another, and can come and go. People with multiple sclerosis often go years between their first symptoms and a diagnosis.
Frequently, the first symptom of multiple sclerosis people notice is vision problems, which can include dulled colors, blurry vision and pain in the eye. This pain is often worsened when the eye is moved in its socket. This symptom is caused by the immune system attacking the nerve that connects the eye to the brain. Visual symptoms often go away on their own within a few weeks or months.
Another possible first symptom is the appearance of strange sensations, which can include numbness in the face, a feeling of tightness, tingling or severe itching. It can also include electric shock sensations when the head or neck is moved, sometimes shooting down the spine or into the arms and legs. Walking problems can include balance issues but can also be a difficulty walking with a normal gait.
