I too had some sharp pains at the surgery sites, especially under my arm where some of my lymph nodes were removed. It's been over a year and I still get them every now and then. I don't know if that's what you are experiencing but no matter what it is, if it's bothersome please check with the docs and make sure that it's normal and see if there is something you can do to get relief. Remember, you've been through A LOT and your body is trying to adjust to everything so be kind to yourself. You will get better in time but be patient. I'm almost a year out since chemo and I still have issues every now and again but overall, I'm feeling terrific. I wish you the same. Love and luck.
