16 years post op BA, left breast has started having this vibrating feeling, what could this be?

I have had my implants for 16 years,they still look amazing I have never had this problem in the past.Out of nowhere today I had a vibrating feeling on my left breast. It's like when you have your cell phone on vibrate. It felt as if I had my cell phone in my bra! It doesn't hurt it's annoying kinda like when you suddenly get a ring in your ear. That type of annoying. I did a self breast exam from my calvacal bone all around the breast area. Nothing out of the ordinary. What can this be?
