You have your hands more than full, Michelle. Thanks for finding a few minutes to let us know how all of you are doing. When my mom was undergoing radiation I found recommendations of aloe vera gel to rub on the skin. It's also good as a general hand lotion. Mederma (an onion-based gel) is designed to help with scars and might also be useful.   

I received the booklet and papers to do with the knee replacement and see that I need to start ahead with stretching, exercise, and strengthening, and also plan a major re-arrangement of the furniture around here. I talked to a friend about mowing the lawn for a month or two. Helpers will be on call for trips out, and the biggest challenge will be The Dogs.
