i am not sure if this a nervous twitch or its connected to a spasm. I have spine issues and i have noticed in bed that i feel relaxed and then all of a sudden my leg or arm will fly out and twitch. I have also had painful spasms in the calves of my legs. I am not sure if the 2 are related. Any advice on what you do to help it. I am not on muscle relaxants, any advice on ones that dont make you too sleepy?
