Robinson campaign communications director Mike Lonergan said Robinson was treated for second-degree burns at Northern Regional Hospital following an incident at the campaign event.
"He is in good spirits, appreciates the outpouring of well wishes, and is excited to return to the campaign trail as scheduled first thing tomorrow morning," Lonergan said.
The news comes days after several staff members resigned at Robinson's office and on his campaign team.
Robinson appeared at an event in Boone on Monday where he addressed recent allegations made against him in a report from CNN.
The claims, which ABC News has not independently verified, focus on controversial comments Robinson allegedly made on a porn site years ago. Robinson has denied them, calling them "salacious lies." His campaign announced it had retained legal counsel to investigate.
In a news release, Robinson said he was confident the Binnall Law Group from northern Virginia "will leave no stone unturned and enable us to use every legal means to hold CNN accountable for their lies." Firm partner Jesse Binnall has represented former President Donald Trump and his campaign in litigation.
