Hi @AliMarie , I had a potacath inserted in my upper arm during a day surgery. Initially it was a bit bruised and swollen and as the others have said a little difficult to sleep on that side for a bit but pillows helped. I also saw my Physio to get some stretching exercises to help get mobility back as it was a little difficult to flip my arm over. I still do the exercises now just to keep things in check. I am really glad that I have it as it has made 6 months of chemo and the continuing doses of herceptin much easier on my body.
I hope that all goes well for you
