mvb70, I haven’t experienced these symptoms before. However, several years ago my neighbor was diagnosed and treated for inflammatory breast cancer. As part of her surgery, they removed most/all of her lymph nodes in her left arm area. As a result, she contacted lymphedema and had large fluid build-up in her arm. Without lymph nodes, the lymph fluid is not able to “flow” and thus the buildup of fluid.
I’m not sure about your dad’s specific case, with his liver surgery and fluid build-up. I had a liver resection myself, for CC (in 2004), and they removed several of my lymph nodes. But I did not experience any type of lymphedema.
I wish the best for your dad and hope they’re able to determine what he is experiencing.
