There's this weird liquid that smells awful in my nose which is dripping down to my throat. Is this normal?

You would be adviced to contact your surgeon so that you can be examined. You will need to be sure there is no infection in the area.

Nothing to fear!!  This is all well within normal as there is commonly increased or altered drainage issues from the nose in the early postoperative period.  The only concern would typically fall 1 - 2 weeks following surgery if dissolvable (chromic) sutures were utilized as these sometimes can become colonized and create a localized infection.  But even in that worst case scenario it is easily treated with a short course of antibiotics and all will be well.  You seem to merely be experiencing a minor increase in drainage issues and these should resolve spontaneously or with the help of a simple saline rinse to the nose on a daily basis.  F/u appropriately with your surgeon and have no fear!!
