Yes, eye twitching can be part of MS. You did not specify if it is erratic eye movements or eyelid twitching. Both happen in MS. Eyelid twitching is actually a small spasm, often as a result of stress or fatigue. Talk with your doctor. Medication can help.
However, it can also be a symptom of several other things. Again, it is a good idea to talk with your doctor.
Good luck. I hope your eye relaxes.
