D.K.
I have been there many times. Including the day I came home with a C-section. Block off a room with you and you little one. Get the TV going. Make yourself as comfortable as possible. Make sure you nap when your little one does. It stinks, but it's life. As for nursing, your little one is already exposed and nursing gives antibodies. I would continue to nurse and call to find out what you can take to make yourself more comfortable without harming your little one. A nice hot shower will make you feel ten times better.
