New York, NY -- Barbara Walters hopes to be back on "The View" in three weeks. She's been gone since the middle of last month after being sent to the hospital for a fall. She revealed for the first time on the air that she fainted and hit her head on some stairs, giving her a concussion. She needed six stitches. Then, doctors discovered she had chickenpox. Walters says she's not "scratching too much."
