Legs... again

I am the luckiest girl in the world. I am married to this awesome guy. I woke up at 6:30 this morning and headed off to class. When I got back, he let me sleep for several hours. I was awakened by this pain in my leg. Now, I have felt leg cramps coming on before and have always been able to concentrate on relaxing my leg and making it go away. This time, I was asleep so I didn't feel it coming and I just woke up in more pain than I have been in a while. I cried out because I was really hurting. He came running and being the PE teacher, Lifeguard, general all around physical therapist kind of guy he is, he worked it out of my leg in no time flat. Now, it was achy for a while after and I could feel the lactic acid working its way through my muscles but I wasn't curled up on the bed wondering if my leg would fall off. He's amazing. I went back to sleep and I got some amazing rest. Why the leg cramps? Why the water weight? Why the RLS? What is with the legs? There is no action going on that far down.
