Foot Swollen/Darned Bandage

After I got back from a client meeting, maybe 3:30 this afternoon, I knelt to scritch Rem's chest, all covered with bandages as it was. Thinking about bandages, I scritched his foot with the bandage around the wrist from the IV--and realized with a shock that the foot was swollen to almost twice its size. I can't believe how unobservant I am, even when I'm looking for problems. Dang bandage was too tight! It came off right then. I wonder how much of his stiff-looking walk & unsteadiness is due to the swollen and probably numb foot?
