I also have a hard time with muscle spasms and, like you, DejaVu, they are worsened with movement.

I get the spasms in my legs, hips, and glutes. Sometimes, when they get really bad, they feel like elastics that are being snapped really hard.

I particularly have a hard time with these at nights. Some nights, it gets so bad that I don't sleep much at all and eventually have to get up and move around to settle them down. But then, as a result, I get a deep burning pain in my hamstring/glute area, accompanied by extremely hot and red feet (which eventually become icy cold, blue and painful), sharp pains in my hips, hamstrings, and glutes, a sensation of cool yet burning water trickling down my muscles, and a sense of weakness with difficulty moving around.

Do these other symptoms sound familiar to anyone?

Sure hope you all find a way to calm the spasms down. I am trying to eat more bananas (for the potassium) and almonds for magnesium.
