Well done @Nefertari! It's tough at the best of times, but you've had a tough time of it.
The Sentinel Node Biopsy is a minefield! Mine was agony, but others experience it like you (I'm envious). It always reminds me about having a baby. Some are desperately keen to tell you about their horror stories! And it's always best to ignore them because we're all so different. Same goes for BC. So don't listen too much to other people, keep your own counsel.
Take it nice and easy, and be kind to yourself. K xox
