Nope, Erza, unlike the others, just wasn't writhing in pain. In the Manga (I think in the episode too) it was confirmed through dialogue that Erza didn't even flinch through the opening of her second origin. Someone speculated (it may have been Gray albeit sarcastically) that Erza's second origin was already opened, as an explanation as to why she's such a beast.
