The doc said it is possible that this is an old injuy that got dug up again. Said it could have been from football injuries that I did have..who knows? Kinda makes sense that 500lbs or whatever could do some damage if there was an injury already. Even though I did squeeze my traps and thought I had pretty solid placement. Anyway, Like Jim says, I'm counting my blessings that I can squat at all..even if it is in the front. Doc says I can deadlift so I'll just plug away at that.
