Boils are painful, as they are filled with pus (since they are an infection), which puts pressure on nerve endings. They will also eventually head up, usually inside of two weeks. They won't just sit there with no head for months. If that were a boil, that guy would have been screaming if he were dead drunk on top of a couple of quaaludes.
Sebaceous cysts are encapsulated, and not filled with pus, but rather sebum. The encapsulation keeps it separate from nerves, so generally no pain, unless the thing ruptures (in which case it becomes infected and heads up). I've had two, and in both cases the uck in there was a combo of "shapes", long strands and round "curds". The long strands may actually be the wall of the cyst disintegrating, not sure. The sebum is thick and semi-solid, feels waxy (it's original purpose is to lubricate).
The larger question is why in the hell do I care enough about his to even post?
