Hi @MillieR
Sorry to hear you are having some strange side effects with your treatment. I had the same chemo regime as you by the sounds of it but finished the Taxol, Herceptin and Perjeta around 7 weeks ago I think and am now four weeks post surgery. I had the pencil poking feeling in my lymph nodes and also a load of stabbing sensations in the breast. I remember the sensations in the breast was quite full on in the first few weeks of the weekly treatment. When I asked my oncologist she basically said she wouldn't take it as a bad thing. That probably doesn't help you much but I would guess we aren't alone with having some strange sensations happen as we go through treatment.
I know we all say this and you have probably heard it many times but try not to google :( you really end up stressing yourself out more and more and speak with your breast care nurses or oncologist if you can and never be afraid to ask them questions. I have also found lots of people are so willing to share their stories and talk things through on here as well.
Take care x
