Could Redness In Soles And Heels Of Feet Be A Matter Of Concern?

Hi, I noticed while at my dermatologist that the soles and heels of my feet were very red. The Doctor indicated it may have something to do with the Crestor I have taken for the past 4 years, and may be drying out the area in question. They gave me some dermatologic cream and told me to keep the area moist. They didn't seem to think it was of great concern. I'm in no pain. and it doesn't itch. Thought I would check with you for another opinion. Thanks, Charles.
