Korda was forced to retire from his quarter-final on Tuesday with a mystery wrist injury while trailing Russian Karen Khachanov 7-6 (7-5) 6-3 3-0.
The emerging star has no idea about the nature or the severity of the injury, saying he planned to head straight to the doctor.
"I had it a little bit in Adelaide a couple weeks ago, but then it went away. During the matches, it was completely fine. Now it just came back out of nowhere," Korda said.
"Just one kind of mis-hit return, and it started to bother me a lot of after that.
"It got worse during the match. I hit one forehand return and after that it was almost tough to hold the racquet at times."
The son of 1998 Open champion Petr, his exit dashed hopes - for this year at least -of the American penning another chapter in the Korda family folklore.
The 22-year-old's sisters Nelly and Jessica have both won the Australian Open women's golf championship and been ranked No.1 and sixth in the world respectively.
Korda himself is a former Australian Open junior boys' champion at Melbourne Park and knows he, too, is on the right track despite his injury setback.
The 29th seed upset two-time Australian Open runner-up and former world No.1 Daniil Medvedev en route to his maiden grand slam quarter-final.
"There are a lot of positives, way more positives than even negatives," Korda said.
"Today was tough, but hopefully it's nothing serious and I can take care of it so I don't have it in the future.
"I have a lot of confidence now. I have always been very close to winning the big matches, but now I'm getting through them. That's a huge lesson I have been learning and I'm really proud of myself.
"Going forward, I'm going to keep on trying to do the same thing, keep on mentally being the same way. I think I can do some really big things in the near future."
