Its along my spine aboout 3-4 inches above the bottom of my shoulder blades. It also hurts when I twist my left side to the right. Feels like a vertibre is severly out my place. I dont have this problem every back day,but when i do it last 2-3 days before it gets better. I think it comes from pull ups . I used no bent overs only rows in power rack today. Hope this info helps.
