Because MS symptoms can affect almost any part of the body, there are no specific warning signs linked to disease onset. However, some symptoms are more common than others as the first signs of MS.

• Sudden decrease in, blurred, or double vision
• Numbness or tingling in body or limbs
• Changes in balance or coordination       
• Weakness in arms or legs
• Heat sensitivity (which may trigger the above)

If you or someone you know experiences these symptoms, it is important to discuss them with your healthcare provider.
