@Nefertari, I too had chemo first, then surgery. I did have a mammogram and ultrasound about 2 weeks after my last chemo, and surgery 10 days after that. Whilst I didn't have a sentinal node biopsy (I knew I was node positive so went straight to axillary clearance), I did have a radioactive tracer injected in to the tumour site the day before surgery, under ultrasound guidance, as well.
You've certainly had a rough time. As @Sister has said, all hospitals will have a process by which to moke complaints, compliments and comments. I would suggest you just jot down the events of the recent past, and how it has made you feel, use what you've written here as a basis. You don't have to do anything with it now, but down the track, when you're ready emotionally you can put it all in writing and send it to the hospital.
I have one other major concern. In amongst the paperwork that was completed the other day, from what you've said, I sispect was your consent for surgery. Also, from what you've said, I don't beleive the consent is valid. In all honesty, can you say what procedure/s you're having on the day, because if not, I wouldn't be letting them touch you, until you know and have a reasonable understanding of what surgery they're recommending and why
