strange "jolt" through body several times a minute.

Ok, this may be kind of confusing, but I will try my best to describe it. About 3 weeks ago now, I began feeling a strange "jolt" through my body, at least once a minute sometimes it happens very rapidly like every couple of seconds. The first day it was kind of amusing, I figured maybe I was just tired, or maybe just imagining it. But after a few days I got worried, and began trying to ask people if they knew what it was, but I couldn't describe the "feeling" I was getting. I said it felt like "electricity" through my entire body, but it doesn't hurt AT ALL. It doesn't make me jump, one time I did drop something but I can't say for sure if it was because of that, because it happens A LOT and I've only dropped one thing. So I've been worried but I don't "think" I have an "emergency" and I figured I'd look real weird going to the e.r describing my symptoms like "well. Its kinda like this but not really" a couple days ago, I decided it feels like the feeling u get when something startles you, or like when u dream u are falling and wake up real fast. But again I am not jumping, or shaking, stuttering (sumtimes I stop speaking on purpose when it happens) anybody have any ideas what this is? Should I be worried? I am 21 yrs old Female and as far as I know, I have no medical issues. I don't have insurance so seeing a regular doctor just to see if maybe this is a problem is impossible for me. Please help if u can because it is beginning to worry me. Could it be a neurological problem?
