Swellen Feet

I'm 4 days out and my feet are really swellen? Is this common?? 

Are you walking?  If you don't feel like walking just sit and flex your feet.

How's your fluid intake? 
No pains in the feet?
No hot spots in the legs?

Probably just bloating from the surgery.  I'd just keep hydrating and walking.  If the feet get warm or start to hurt could be a blood clot but chances of blood clot in both legs is nil.

Chances are just fluid retention from the surgery keep flexing while sitting.  It should go down.  My feet swell from sitting for too long in one position.

Thanks for the input. I am walking - about 30 minutes a day. I even went for a bike ride this afternoon. Just a short one. I'm taking in about 40 oz of fluid and about 50-55 gr. of protein. Getting my fluid is really isn't a problem except I don't have enough hours in my day. 
My feet don't hurt - they are just puffy! I'll just keep doing what I"m doing and hopefully they will go down soon.
Thanks again!
