My knee has been bothering me but I've been walking anyway because it doesn't feel worse when I walk. But then I spoke to a woman who asked if I knew when I had torn my miniscus. I said I didn't and she said she didn't either but she knew when she ripped the whole thing loose. It was very painful and she hit the floor. I asked what she was doing when it ripped loose. She said she was doing aerobics. I thought, "Well, my knee is safe!" But the more I walked, the better I remembered the doctor's assistant saying in a hesitant voice, "Well, it's all right if you walk, but don't shovel or squat."
So I was walking but then I started thinking, 'What if he didn't mean five miles a day with enthusiasm?'
So I've dropped back to half what I was walking...or a little more, but more gingerly than before.
