So three days ago I was standing in my bathroom and I swear to god It felt like someone was dripping cold water down my leg! (there wasn't anyone in the room with me) This has happened a couple times a day since!

What is going on? AM I loosing my mind? It's crazy, it seriously feels like ice cold water dripping down my leg.

All my problems are in my c4-T1. Could this be related to my neck and be a nerve thing? or am I just loosing my mind?:
