Anyone else experiencing Restless leg syndrome??

I am 10 weeks pregnant with my first and every night I find my self waking up from time to time to move my legs because I feel uncomfortable I don't know how to explain it any other way but just feeling like moving my feet makes me feel better or comfortable. I didn't know I had this and neither have I talked to my OB yet but being that I can still sleep somehow I'll just wait till my next appointment. But today I got this weird cramp on my foot it scared me so much because it somehow felt like my foot was going to stay cramping forever and in seconds it went away. I read that I'm not the only one experiencing this but this is very odd never heard of this until now. I kind of self diagnosed my self but its been happening so muvh theres no way this isnt itb. Any of you ladies has or is experiencing this? If so how did you deal with it? Did it go away or get worse?
