Walters, 83, was hospitalized last month after she fell and cut her head. She was later diagnosed with the chicken pox. She has been recovering at home for more than a week.
"I have been a little weak. I am not in any pain. And I'm not scratching too much. I'm not itching away," Walters said. "I just feel sort of weak and tired, and I probably won't be back on the program for about three weeks."
