10 MS Symptoms
Symptom 4: Muscle Spasms
Muscle spasms are a common symptom of multiple sclerosis. These spasms are caused by an increased muscle tone of the limbs. People suffering from this disease can have muscle spasms even during sleep when their foot, for example, rubs against the sheet. Even minor stimuli, can trigger real muscle spasms, often very painful as well.
Muscle spasms can affect any muscle in the human body, even though the legs are usually most affected. In cases of flexor spasticity, the hips and knees are bent due to spasms of the hamstring and hip flexor muscles, which makes it very difficult to straighten the legs. In extensor spasticity, the hips and knees are crossed over the ankles or very close together due to spasms of the adductor and quadriceps muscles of the legs.
