No pain. It only lasts for a few minutes. at worst, up to a few hours. I knew a girl back in college who probably has this. it is just her legs though. I've been experiencing these episodes since i was 19, so about 3 years now. I'm sorry that its lasting over a year for you, it must be horrible to cope with! Luckily, for me, if i get someone to rub my arm or leg or hit it (without causing it too much pain), it will make the episode go away quicker. but that is only if i can get my mouth to work enough to say coherent words. sometimes my mouth shuts down and i cant talk. but again, like i said, mine only lasts for a few minutes...
