Is there a Doctor in the house?

As tempting as it may sound, i'd suggest you to try and avoid slicing it open on your own. it would only induce bacterial infection and yuo could put yourself into a much worse situation, like amputating you leg or something.

it looks like a cyst to me, though. i've had one before right on my chest. it was considered as third nipple. it was cool when they squirted it out.
