Hiya,sorry you have found yourself here and you are having to go through all this over Xmas, I had lumpectomy and Sentinal node biopsy in March and felt pretty good the next day, it's not a bad op and I felt well enough to walk out of hospital a couple of hours after coming around from surgery, you may feel a bit tender and must be careful not to use your arm on your Treated side too much but as long as you have support at home then you should be able to enjoy Christmas Day with your son and your lunch!
