This is relatively weird, but it's been happening during the last few weeks, and it's bothering me.

I've been noticing muscle twitches (no cramping or discomfort, only twitches) in all parts of my body. It could be anywhere from a toe to a finger to my back. However, it never happens when i'm active, it only happens when i'm at rest. I've woken up with a big twitch in my arms or back a few times, but no other time has it happened. I've heard of all sorts of benign muscle twitch diseases, but the problem is that there's no other symptom. Weakness, paralysis, rigidity, and spasms are symptoms of almost every single muscular/nervous disorder i've seen, and like I said, this is only muscular twitching and only when i'm at rest. I've also noticed that the more I think and worry about it, the more it happens, which makes me believe it's related to anxiety.

The only other point of interest might be the fact that I lift weights frequently. But it's not beyond normal; it's only three times per week, one hour each session. I've been doing it for seven years, though, and I don't see why it should suddenly start causing muscle twitching problems now.
