@sophie, firstly congratulations!
I had the breast bad on aswell and hated it, so uncomfortable, I couldn’t breath and it was just a pain.
I didn’t wear mine properly and im now 4 weeks PO – I wore mine to bed after day 5 only and I my implants have stared to drop now… as far as ice pack are concerned they saved my life!! well they help soooo much with the swelling and pain so call the nurse up and ask why you were told this… you cannot use heat pads. im sure you can use ice packs from day 1.
good luck xxxx
