Shoulder impingement on squat?

[jkahnke]

I'm a 6'4'' 26 year old guy, ~250lbs. Been doing the LP for a little over 2 months. Last workout was: Squat 270 3x5, Bench 150 3x5, Deadlift 340 3x5. I have long arms (~6'9" wingspan), which I think might be part of the problem here: last workout, my left shoulder started to hurt fairly badly during my sets of squats. Was able to finish the workout, but was not able to complete a work set today (my next workout), due to shoulder pain getting so bad during warmups. Has anyone heard of this happening before? Any recommendations on how to avoid going forward? Shoulders had felt fine and were actually getting more flexible before this.
