Hi , I am 17 years of age and have discovered a dent on the back center part of my skull. The DENT doesn't hurt at all nor do I experience migraines or headaches. But the DENT radiates the weirdest sensation I've ever experienced. I'll do my best to explain the feeling. The sensation includes an electric almost prickly feeling that spreads to my jaw and upper ear. The DENT is also extremely warm to the touch and feels hollow and numb at times. But when I press on the DENT or rub it it is the most euphoric feeling I've ever experienced.The skin is also tender. I really need insight into what this might be.
