Twitching

I didn'treally know where to put this question so I thought I would put it in the general questions and anwsers.

Awhile ago though i'mnot sure how longexactly I would twitch ramndomly every once in awhile. It would only be my right side usually my arm neckand head. My head would go down to my shoulder and my shoudler toward my head. My arm would jsut kinda twitch..When I twitch hard it hurts my neck. Then it started happening more and more often to where it would be multtiple times a day. Sometimes I could feel it before it woudl happen in my whole body and maybe be able to stop it. After awhile it calmed down a bit again only happening once in awhile again. But now again it has started pretty bad. I have these little spats during the day. I will twitch once and then a few seconds alter again and so on for about 3-4 times. Sometimes it's a double twitch. But lately it isn't jsut my right side . Every now and then it could be both my shoulders or something like that. Can anybody tell me whats going on? My mom says it's nerves.. Im just not sure. I woudl appriciate any help given! Thank you
