Recently, most often in my foot, I've been having weird muscle spasms. I always used to have them, but rarely. Now I'm getting them more often. It looks like my foot is rumbling from the inside. They get to the point where you can actually see my foot moving. Currently I'm on my bed and my right foot feels really weird, like its tightening. It's really odd. I was always told this was normal, but I'm not so sure. It also happens to my leg. Thanks!
