Oh well - bilateral mastectomy and lots of lymph nodes from both sides since cancer everywhere. Some lymphedema that comes and goes more in the left arm. I do blood pressure on either arm and when possible either wrist. Sometimes I have them do it twice - maybe in the other arm - if we get a reading that seems off. (I track my readings). As for blood draws - geez - had so many taken from both arms that my veins like to move, blow etc. Actually I now prefer either hand because I hate when they take it as a challenge to "dig" around. I have asked about other locations for blood pressure and blood draws from all types of providers and short of having another port put back in or going to the hospital, they are just not set up.
