@CathyMac You'll have lovely drugs before and after, and will probably have a button for you to self-administer pain relief in the following days; you can press it as often as you like. You can't overdose. Their machine shows how many times you've used it and you must use it enough to help - don't wait for pain to crush you.
The worst pain I had was in my shoulder, for some time - maybe even a couple of weeks. It's because they put your arm up during the whole surgery to give them free access to your breast and underarm, so your shoulder joints and muscles become sore. That was the worst of it for me.
One of my best friends was waiting for me in the ward, with chocolate and ginger beer, and to unpack my bag into the drawers. :)
