I've got two of those that I'm trying to get rid of right now - a small one and a medium-sized. They're a bit tender to the touch, but I doubt that they're cystic in nature.

Mine is being stubborn and is lingering for about a week. I guess its one of those things that just has to work its way out and

go away on its own, so I wouldn't worry.

You can try tea tree oil, peroxide or salt water to speed up the healing process. I'm using the oil, epsom salt and ACV (to try to bring them to a head)...bringing out the big guns, right?
