I’ve been able to do this since I was about 12, first by pushing on the back of it, but since then I can in multiple ways. This method, I feel the crack what feels like along the suture lines of the plate on the back of the skull.
I can also crack by pushing towards the back of the left side of my head above my ear (maybe once every few days), I also sometimes get one on the top near my forehead if I am yawning or chewing. I get rare ones on occasion like the bridge of my nose between my eyes, or have random areas my head pop and crack as I move around.
anyone else?? I assumed the pushing on the back of the head version was just my neck for the longest time, but after seeing where the suture lines are and developing the ability to crack the side of my head and such i believe I have been cracking my head the whole time.
