Post-surgery notes from the cancer ward

My husband has been home from the hospital for six days, and is 13 days post-surgery. The surgeons believe they got everything--the mass, the nodes, the secondary lymph nodes. He is weak, and mostly incredulous at how weak he is. As he has been unobtrusively healthy his entire long life, he has never really experienced to what extent surgery in your body flattens you. The day of the surgery found high gusty winds, up to 55 mph, slamming trees against the windows of the waiting area. This made waiting even more unsettling than it already was.
