A business executive injured his leg skiing one weekend.
By the time he got home Sunday, the leg was very swollen and he was having difficulty walking, so he called his physician at his home. The doctor told him to soak it in hot water. He tried soaking it in hot water but the leg became more swollen and more painful.
His maid saw him limping and said, "I don't know, I'm only a maid, but I always thought it was better to use cold water, not hot, for swelling." He tried switching to cold water, and the swelling rapidly subsided.
On Monday morning he called his Dr. again to complain. "Say Doc, what kind of a doctor are you anyway? You told me to soak my leg in hot water and it got worse. My maid told me to use cold water and it got better."
"Really?" answered the doctor, "I don't understand it - my maid said hot water."
