For as long as I can remember, going to the barber's was the worst experience of my life. I remember since I was 9. The pain still happens to me when I get it cut nowadays, I've just kinda learned how to suppress it a little. I'm not really sure what it is, but if someone is behind me, I get this painful sensation behind my left ear on my neck, and this pain also resonates in my left bum cheek, It sounds even weirder writing this down but I have no clue what it is, I did a test with my friend to try figure it out.

I faced with my back towards him and he moved towards me and the painful sensation started happening, I don't know what it is !

Earlier today I put on some headphones and started listening to an affirmation video and whenever the guys voice came into the left of my ear, I would get the same painful sensation, I hope I'm explaining this enough to maybe get some help but anything would be appreciated.
