I am so glad you get to finally have the surgery and really be on the road to being better by Thursday.
it is great that the doctor is booking a nice, long block and going to have time to calmly deal with any extra he finds once inside, but can leave as much there as is reasonable. And YAY that he is considerate of poor Matt sitting and worrying--is there someone who can wait with him that day?
Honestly, as horrible as those cysts sound, growing so fast is a good sign as far as nothing being too scary (I think). and I bet you will feel so much better once they are out and you recover.
I'll be sending you every good vibe I can all day on Thursday--and I bet so will half the DIS.
