I've noticed this for a few years now...my ankles have a reddish-purple tint to them, as if they have been badly bruised, but they aren't. There is no pain in my ankles, but while the skin on my feet is perfectly soft, the skin on my ankles is calloused and hard.
What is making my ankles look like this? Could it be because I am overweight? (height: 5' 4.75" weight: 143 lbs. age: 16)
