I have 2 mm subluxation in my c7-t1 with mild bulging disc. i've had a couple bad stingers. i also play football. what's the cause of this?

Arm stretch zingers: the brachial,plexus, carrying nerves down the arm can be irritated by a rapid stretch of the arm on the base of the shoulder, causing the zing you describe. Doubt the neck stats you list caused,this problem, BUT a warning that you are causing trauma there that will get worse. You will remember this note in 10-15 years after it becomes symptomatic. Keep your pain docs number handy.
