Fasciculations

I've been on my TMS misadventure for a long time now, with symptoms coming and going all over me—from ol' fashioned back pain to gastritis and IBS to knee and other joint pain. I've had muscular fasciculations (twitches) on and off over the years, usually in my hands. But this latest bout over recent weeks, in my left hand, has been especially annoying; doesn't hurt, but it keeps me awake all night. (Imagine someone poking the palm of your hand every 3-4 seconds all night.) Naturally, I suspect TMS. Would I be justified in thinking that? Thanks for any info.
