I was doing a few lat pull downs yesterday and did something to my neck. I have a pain radiating from my left occipitals down my upper traps to my left scapula. And nothing is helping (heat, cold, massage, drugs) It seems like I do this a few times a year and it goes away after a couple days. I'm pretty sure my form is good. Maybe too much weight? Or could something be inherrently wrong in my bone/ muscle structure? I know I should just go see a chiro but thoght I'd check to see if any of you people had any ideas?
