My lower back is still sore; there was a "wobble" in the bottom of my squat - something kept letting loose, couldn't fix it all day.  Three reps with 415 was HUGE - it was hard because my form was off but I did all 3 reps! 

Now today, my lower back is killing me.  I must have rounded my tailbone at the bottom of the squat at some point.  I did that once before a long time ago and it feels the same today.  Ouch!
