Randomly at times, I will have something in my neck just shock me. Sometimes it's on my left side, sometimes it's on my right side. Almost like that feeling you get when you push the trigger on a shock gun. It's sudden and abrupt and it lasts less than a second, it's really fast.
What could this be?
I have somewhat high cholesterol, I'm fit, athletic, 6'1", 165 lbs.
