House told ESPN's Jayson Stark that he is not feeling any lingering effects from the injury, which he suffered in the ninth inning of Friday's game against the Detroit Tigers.
"Obviously, it was definitely a rough day yesterday," said House, who was released from Lakeland Regional Medical Center earlier Saturday. "Whirlwind experience -- and I'm doing a lot better than I thought I would be doing today. Definitely got some good news at the hospital. Just excited to be back here and kind of get into a normal routine again."
Blue Jays general manager Ross Atkins confirmed to Stark that House does not have a fractured skull, emphasizing that the left-hander will be tested and closely monitored for a concussion.
House also acknowledged that he isn't certain whether he has a concussion but told Stark that "for the most part, I feel fine."
House was hit on the back of the head by a ball off the bat of John Hicks. The ball ricocheted about 30 feet into the air before catcher Mike Ohlman caught it.
House fell to his stomach and was face-down on the mound for nearly 20 minutes while trainers tended to him. He was put onto a stretcher and gave the crowd a thumbs-up as he was placed into an ambulance.
"I remember exactly letting the ball go, it coming back to me, getting hit, trying to stand back up," House told Stark. "The ride to the hospital, the whole conversation, the whole conversation I was having with everyone. So I remained conscious through it all."
Tigers manager Brad Ausmus said Friday that it was among the most frightening things he has seen in a baseball game.
"It was scary," House said Saturday. "You don't know what's going to happen to you. You don't know if you're going to be OK, if you're going to survive this.
"It's scary, because I've seen someone get hit in the head. When I was with Cleveland, I saw Carlos Carrasco get hit in 2015. You're terrified just watching it. And actually being that person is not fun because you just don't know."
