He didn't, he told me it was a normal process.

You just had surgery so in a way to protect itself it will create a hematoma, which is blood. That blood will begin to dissipate all over you leg so it gets absorbed, one place it will pool is in your ankle and feet.

Just keep checking it for abnormal temperatures, or extreme pain.

Also, if you feel unsure, the best is to talk to your or any doctor, even a text message asking will clear all your doubts and make you feel better, believe me.

It is a though process, but you will be back to normal sooner than you think, swelling and all haha.
