The French rookie's Toro Rosso veered of control at the end of the Autodromo's long front straight during the recent Italian Grand Prix.
Vergne's car launched over a kerb and landed with a thud, and he immediately complained on the radio about a sore back.
He was taken to the medical centre with pain in his back and head, but declared: "I am fine."
And now in a post-race blog, the 22-year-old has revealed he also sustained "a few bruises" and a sore neck.
"I do feel pretty stiff across my back and neck but I think that will go away over the next day or so and I'll get on with what is going to be a pretty busy schedule until Singapore," said Vergne.
Toro Rosso said the crash was caused by a suspension failure.
