You can always call a surgeon's office after hours. If you listen to the message played, it'll give you a way to get in touch with a nurse on call.
Make sure you're wearing your compression vest, draining whatever you can regularly and keeping track of the amount of drainage. Take your meds, drink some water, and make sure you're getting up and walking around regularly. Swelling is very normal, as is soreness. I would suggest calling your surgeon's office if you haven't already. If it sounds bad to them, they'll have you come in.
