How do I get rid off muscle spasms at night? I'm a healthy 27 year old girl,I don't know where those come from I go to sleep around midnight, I wake up around 4 am spasming. It almost feels like I'm being electrecuted. It starts in my shoulders, goes down my arms to my fingertips. Same with my legs- it starts at my upper body and shoots down my legs to my toes. I can't say it really physically hurts but it's emotionally annoying and keeps me from sleeping.  On some occassions, the spasms "throw" me around the bed, they can get intense.
It happens ONLY when I lay down or when it wakes me up in the middle of the night, never while walking around or sitting. I'm a healthy 27 year old, I don't see how this could be happening to me and how do I get rid off it. If I had to go to a doctor, what kind of doctor takes care of such a thing?

Summarized question: What can cure muscle spasms at night and what doctors specialize in these treatments?
