I’ve been told that it’s the surgeon that makes the decision whether you need one or not.
I’m having unders and I’ve been told that if I don’t get given a band I shouldn’t panic as it’s not essential for everyone.
You’re not the first person to post on here panicking about not having been given a band. I do get a little cross that your nurse would start saying what you should and shouldn’t have had! It’s your surgeon who should be telling you not the nurse, and the nurse should be discussing things with your surgeon before saying what should or should not have been done .
Your nurse should not be filling your head with worry and panic without consulting your surgeon for more information and reasons behind his/her decision not to give you a band.
