It’s been almost 3 weeks since my lumpectomy and SNB. I started having pain in my arm a few days ago and then noticed the cording. Does this ever go away on its own? I’m doing exercises at home but can’t get into physical therapy for another 3 weeks. In the grand scheme of things, I’m sure this is nothing compared to what I’m about to endure during chemo and radiation, but it’s causing a lot of distress right now. Anyone else dealing with this?
