Muscle spasms or extreme tightness is more common that twitching. Twitching is more common in myasthenia gravis, Lyme, disease, certain deficiencies and many other diseases.
Twitching can occur in MS. It isn't considered a diagnosis symptom. It can occur in conjunction with brain or spinal cord damage.
