Does anyone know why you cant take a muti vitamin or herbal supplements after surgery? I think cuz it can thin your blood??? Well, im asking cuz i had surgery about 3 weeks ago, and im not healing....(open wound) so, my doc put me on zinc and a multi vitamin, to help heal me. Oh, i had a breast lift...you can read my nightmare post on here!!!!! Anywayz, i know i can ask him, but my appt isnt til the 14th and im curious.
