What's this strange bump on my neck?

Okay, about a year ago I noticed a small bump on the back of my neck, just off to the right from the center. It was about the size of the end of a pencil, about a month ago, it grew to the size of a dime, and now within the last week it has grown to a...

size between a penny and a nickel. And it hurts now. Anybody know what it is, or why its getting bigger?

It could just be a cyst. That's nothing but a little water pocket under the skin. However, I would see a doctor just to be sure. If it's a cyst all they will do is drain it with a needle. It doesn't hurt and, in fact, feels better as soon as the needle is inserted. I know from experience. Good luck!

Okay, thanks for the advice. I am absolutely terrified of needles. lol. I can't feel them, but gah! Which is stupid cause I have to take my blood sugar all the time anyway. Anyway, I have to go to the doctor next week, maybe I'll ask them about it, but that would be kinda a weird thing to ask an orthopedic specialist.
