I see. I’m very sorry about your recurrence. Are you a candidate for Verzenio? From their website: “Verzenio is approved for women with HR+, HER2–, node-positive early breast cancer with a high risk of returning, as determined by a doctor, or certain types of HR+, HER2– metastatic breast cancer.” I take it in addition to an AI; my oncologist is a big fan.
The lymphedema exercise class I do is in-person at a cancer resource center in my city. The class is called Healthy Steps and is based on the Lebed method; if you don’t have an in-person class available to you, check out this link: https://www.gohealthysteps.com/find-a-class.html
It looks like there are YouTube videos and maybe live classes online. I find Healthy Steps extremely helpful, and can tell a difference when I miss more than a week.
