I am obsessive about no BP, blood draws etc. from my affected arm. I changed PCP docs once after her assistant ARGUED with me about BP cuffing that arm! (If it was a life-or-death matter and that was the only place they could draw blood or something, that would be different…). I wear a medical alert bracelet on that arm. I have had three surgeries, including total hysterectomy, for pelvic floor prolapse (unrelated to my BC, but it has been its own nightmare) and each time have worn a fluorescent pink “lymphedema alert— no needles, BP, etc” sleeve to surgery and during my hospital stay, with my doctors’ knowledge and consent. So far I’ve had no problems during surgeries.
