Hello, I am currently being treated for breast cancer. A medi port was inserted, about 9 weeks ago, for easy access. A few days ago I was coughing a lot, I also had developed neuropathy of hands and feet....I noticed my neck started to hurt, as if perhaps I had pulled my port loose from my artery after all of the coughing. I asked my Oncologist to look; She ordered an ultrasound from Cardiology. It confirmed that I had developed deep vein and superficial clots in my neck. I am on my 3rd self injection of blood thinner(2x per day). The pain has spread into a wider area and is more intense. Should I be concerned(?) What symptoms should prompt a closer look from a Dr.(?) What should I expect as a Prognosis????
