A team spokesman said he had been given the all-clear.
"I still have all my teeth after the impact," the Spaniard, who finished fifth in the race, told reporters after the incident which occurred when he ran wide to avoid a collision with Jean-Eric Vergne's Toro Rosso.
"My back is obviously in pain a little bit because it was a big hit."
The double world champion, second in the standings in a season already won by Red Bull's Sebastian Vettel for the fourth year in a row, said the impact had triggered an alarm on the chassis.
However, he played down any concerns about his fitness for the next race in Austin, Texas,
Ferrari are battling Mercedes for second place in the constructors' standings with two races to go.
