Hi...not sure...if Zygy2 is around I hopw she responds as she has dealt with this.....several times unfortunately....but she is very well informed on this topic.
Unfortunately, I've dealt with this as well. My drainage ended up not being from the pseudo. Rather it was an internal stitch that had somehow popped up. Please get to that Dr as soon as you can. I procrastinated and ended up with a csf infection.
