I notice that kind of buzzing tremor when I am stressed and twitch at night during sleep (my wife tells me) more so when I am overtired. I have fasculations kind of through my body, especially if I am more tense. However, I have the fascic. more predominant in my arms/hand as I extend and contract my arms (more in the right). If I am not stressed or not thinking about them, they are not noticed much by me. After reading replies on this web it felt to me like BFS. I have no pain or loss of strength and I am in a gym 3 days a week doing some weightlifting.
I had done some exercising in the days before the test. The doc had not said anything, but I think I exercise more than many people (I have for many years so it is a part of my routine). I have another CPK test scheduled in 10 days so I will hold off on the gym. The reason I was thinking the elevated CPK had occurred was because in the weeks before test, I had changed my routine to use a lot muscles I had been kind of ignoring at the gym and had some sore muscles. Thanks.
