Roto Rooter?

The drain had been working throughout the week, pulling some funk from the abscess.  It was mostly blood and fecal matter, meaning the sinus cavity hasn't completely closed.  As of this weekend, the output has completely stopped and pain has started to increase in the buttocks area.  I'm not sure if this is a result of just having the drain or if something is actually wrong with the catheter and that's also the reason that it's not draining any longer.

I have contacted the Interventional Radiology doc on call this weekend both yesterday and today.  They don't have anybody in house today to manage this, but I'll be heading in tomorrow, rather than Wednesday to see what's going on with the catheter.  If there is truly a pain in the ass, this is actually it.
