Please don't pop it yourself. Your skin is designed to protect itself, and will stretch as much as possible in order to keep bacteria from entering a wound in the skin.

As always, watch for signs of infection. This answer should not be considered medical advice...This answer should not be considered medical advice and should not take the place of a doctorâs visit.
