Common early symptoms of MS include sensory irregularities, such as tingling, numbness, itching, tightness, burning, shooting pain in the back and limbs, difficulty walking, blurred or double vision, red-green color distortion, eye pain and vision loss. These symptoms may at first be brief and mild.
The first serious attack typically appears between the ages of 20 and 40, and can last for weeks or months. The symptoms can range from minor physical ailments to major disabilities. Other common symptoms include balance and equilibrium problems, bladder and bowel dysfunction, behavioral changes, cognitive dysfunction, facial numbness, motor abnormalities, sexual dysfunction, hearing loss and vision problems.
Muscle weakness can involve the arms and legs on one side of the body, both legs or all extremities. Muscles can tighten and contract spontaneously. Many individuals with MS suffer from fatigue and need to sleep during the day to continue their activities.
