Torn ACL & MCL. Why is my foot numb and swollen?

I tore my ACL and MCL on Thursday skiing. My knee hurts and is swollen. I can't walk on it and I'm in a brace and on crutches. Totally sucks. Anyway, my foot is numb like it's waking up from being asleep and it's pretty swollen. I did not injur my foot. Is this normal for an ACL injury? I'm seeing an orthopedic surgeon this week. But I just wanted some thoughts from anyone that has been through it. I'm also really worried because I have a 18 month old son. It's going to be really hard to take care of him with only one leg. Thanks for all the help! :)
