1-Balance and coordination problems: Movement problems are a hallmark of MS. “Impaired nerve conduction means muscles are not behaving the way they used to,” explains Kalb. People may report they feel suddenly weak in one limb or they may find objects slipping easily out of their hands. If there’s damage to the cerebellum, the part of the brain that controls balance, people might also be unsteady on their feet and prone to falling.
2-Spasticity: Spasticity can involve both stiffness as well as involuntary muscle contractions. As a symptom of multiple sclerosis disease, it’s most common in the legs and may manifest as a mild feeling of tightness in the muscles or as more severe pain. In extreme cases, spasticity can cause a person’s body to become distorted and twisted, almost as if they’re folded up like a pretzel. The symptom often goes hand-in-hand with weakness of the limbs or other parts of the body.
