Hi Jo
You actually need to take very little as it’s a day case!
Wear loose front-opening tops. You won’t be happy having to lift that arm and breast into a t-shirt or sweater when it’s time to get dressed! It’s hard to predict the weather so the ward may be too warm or too cold - provide for both, especially cosy socks and something like a cosy cardigan to wrap round you if it’s cold while you’re kept in bed. You can then wear it round your shoulders when you leave.
Most of the stuff I took was unused (puzzle book, newspaper, novel) but think about things that make you feel good - I took essential oil to sniff occasionally and Rescue Remedy for reassurance. You’ll be too dopey to read after but a book/kindle does help In the waiting time prior to surgery. Small mints are good if you have a nasty taste in your mouth or you are dry-mouthed afterwards, or the Ricola sweets you can buy from pharmacies.
Basically, you won’t be there long enough to miss anything. If you were staying overnight it would be different but your time is mostly accounted for and, after surgery, you will be groggy and, when that has lifted, be discharged into someone’s care so there is no need for much. Maybe others will suggest extra things.
I’d leave your handbag at home, with your purse/wallet, and only take your phone if you really must take that selfie or text people. Similarly, leave all your jewellery at home as it has to be removed for surgery.
For the recovery period, get in both paracetamol and ibuprofen in case you get pain. You’ll be advised to take paracetamol anyway but, if your pain is severe, you can alternate them every 2-3 hours for greater effect. However, check with your breast care team to be on the safe side. Don’t assume it will be very painful. I didn’t use any pain relief at all and I’m no Amazon.
You’ll need to drink plenty of fluids so make sure you have a range of things available. It’s hard to know how you’ll react to a general anaesthetic but err on the safe side and make up or buy in some soups till your appetite returns. Make sure you have front opening pjs (George at Asda do some very good pjs, front buttoning, light and stretchy); and front-opening loose tops (I nicked a couple of my husband’s old, soft shirts). As you are having the SN removed, you may have a drain for several days. This came as a shock to me and was a great diversion from any misery as I worked out ways of getting the damn thing round with me. Eventually I devised a papoose from a scarf! Some hospitals provide a carry-bag.
Afterthought: in case of an allergic reaction to the dressings, have a good antihistamine in the house!! Yes, I did
I hope it all goes smoothly for you. Make sure you do those exercises!
