Do you get Cell Phone "Twitches" ?

I hadn't really ever thought about it before but
I have carried a cell phone in my pants pocket for well over 3 years now.
I've become one of those people who feels "naked" without my phone and I'm "lost" when the battery runs down or I have no service (like when I'm camping).

What tipped me off to this whole dependency situation was when I began to notice that I sometimes get "twitches" in my upper thigh area (where my phone normally rests against my leg in my pocket).  This makes sense when you consider my phone is on "Vibrate" about 90% of the time ... but it still really freaks me out.  Why?  Because often I hadn't actually gotten a text or a phone call ... my leg just
"twitches" as though I had gotten a message.

Am I the only one who is experiencing this weird physical phenomenon?
