On the bottom right of my chin, directly below where this bump is, fluid of some unknown sort would build up and lock
in place. when this happened I could feel a sharp, throbbing
pain. The fluid would lock in there for a short while, noticeably swelling the area for anyone who would feel the area, then, it would drain to somewhere in slow and pained pulses. I learned to check the wideness of my yawns to prevent this problem from occurring and over time forgot about it.
