Hello there!
I had a lumpectomy for a 1cm lump on the upper outer quadrant and lymph node biopsy in December. I arrived at the hospital at 7:30am, however there were delays due to the junior doctors striking and the first patient didn’t go to theatre until 10:30am. There were another two to go after her and before me and I didn’t go to theatre until 4:30pm. I filled in the time by reading, chatting with the other women and nurses and a lot of stretching and pacing! 
I was a little tired and groggy when I first woke up but actually became quite lively very quickly after that. I was told by the surgeon that I had a lot of stitches and that 5 lymph nodes were taken in total. The pain was nowhere near as bad as I’d expected and I could move a lot more than I thought I would be able to. I just spent the next couple of weeks taking it easy and the pain, bruising and swelling subsided and movement came back more and more each day.
I took the dressing off after two weeks and I have one incision (they’d done both procedures through this) measuring just under two inches, but other than that, my breast looks exactly the same as it did before.
Sleeping was the trickiest thing for me as I’m a die hard side sleeper and had to sleep not only on my back, but also propped up for quite a long time. Two months out and I’m back on my side again. Oh and the surgical stockings. I had to wear these for two weeks after the surgery and didn’t mind them during the day, but seriously fell out with them during the night!
I received the results at my pre-arranged appointment four weeks later and all margins and nodes were clear.
I hope this helps and feel free to ask anything if this has thrown up more questions.
Wishing you all the very best x
