The 18-year-old was rushed to an Idaho hospital on Saturday after an unfortunate mishap on the ski slopes.
Patrick later tweeted photos of himself wearing a neckbrace as he was being transported on a stretcher to the nearby medical centre.
The Terminator star's son provided an update for his Twitter supporters on Sunday (March 11) and revealed that he is already beginning to heal from the undisclosed injuries.
"Appreciate all the messages, love all you. I'm actually feeling really good today, and I even went skiing again today. Thanks again!!" he tweeted.
He apparently returned to the slopes yesterday afternoon.
Patrick's younger brother Christopher Schwarzenegger suffered broken bones and a collapsed lung in a surfing accident in Malibu last July.
