Lindsay Lohan -- Most Painful Movie Night Ever

Still hurtin' from having her wisdom teeth removed earlier in the day -- Lindsay Lohan put herself through even more agony in L.A. last night ... by going to see "Sex and the City 2."

On the way out of the ArcLight theater, Lindsay didn't want anyone to see her face .... and after watching that flick ... can you really blame her?
