I too am having heart surgery to repair ascending aortic aneurism. One thing I have a little different is I have lymphedema in my arm from breast cancer and I am concerned to go without any treatment for it for several days or weeks. I have also read heart surgery can cause lymphedema. I am going to talk to my doctors and lymphedema therapist about this but just wondered if anyone else had experience with this. Along with some family problems I won't go into it all feels like too much to deal with.
