Promising (or warning) viewers that she was about to "tell you more than you want to know," Barbara Walters returned to "The View" Monday following a six-week ordeal that left her with a head scar and memories of an itchy recuperation.

"Today after a lot of scratching and rest, I am fine and I am healthy," Walters said, then lifted her hair to reveal the scar from a gash over her right eye. "People have said I should have my head examined," she said. "I did and I'm fine."

Looking reasonably happy and healthy for someone who has recovered from both a serious head injury and chickenpox, Walters explained that early New Year's Day, when she was at a friend's home in Miami, she hugged a well-known actor also in attendance (whom she declined to name).

She learned later that he had shingles -- an adult-onset reaction to what is normally a childhood illness, chickenpox. Shingles is contagious to adults who have never had chickenpox, she explained.

Then, a few weeks later, while at the British Ambassador's residence in Washington for President Barack Obama's inauguration, she fainted and her head struck a marble floor. She learned at the hospital that she had also suffered a concussion.

In an interview aired on "World News" last night, she told David Muir, "I did not have headaches. I did not have vision problems. I would not have known that I had a concussion if I hadn't had CT scans. I felt a little lightheaded . . . but that's all." She added, "The only cure for concussion was rest. The pox came and went weeks ago. The head injury took longer."

Walters, 83, had two special guests greeting her at Monday's taping, Mayor Michael Bloomberg and Regis Philbin. The latter confirmed reports that he is returning to TV -- in a show for Fox Sports.
