Yuck! My nasty drain! TMI Alert!

I Andy and I stayed up a little late to watch a redbox movie. I went to use the bathroom and noticed (TMI Alert) pus like goop ozing from my drain site! I had my drain out 4 days ago and it had been scabed over. The drain area and up to my incision had been hard and painful for days, not nearly as painful as when the drain was in but close. My doc told me it was not infected and I had nothing to worry about. Any way me being me I squeezed the area and more came out. So I drained as much as I possibly could from the area. Yuck! There was a ton, it just kept coming! The color and texture changed to a more normal looking fluid and we covered it with gauz. The pain and hard/swollen areas are gone! What the heck was all that about?  Major fluid build up that needed to be drained? Pus? Infection?? I'm freaking out a little hoping it's not infected. We probably didn't need to do this but we called the plastic surgeon on call at our hospital. I feel bed now because we are going to wake up some poor doc to tell him about my oozing drain site, just so he can tell me to call my doc in the morning. I can't believe that was what was causing all that pain for the past few days.
