The eldest son of former California Governor Arnold Schwarzenegger and Maria Shriver was taken to hospital on a stretcher on Saturday after a skiing accident in Sun Valley.
Patrick, 18, was recovering and feeling well enough to post details on Twitter and photos, People Magazine reported.
"Little ski accident today. Some bruises and stiches down back and but (sic). Thanks to sun valley doctors for everything," he posted.
The accident came about seven months after his little brother Christopher, 14, was hospitalised after hurting himself while boogie-boarding.
