Other than going completely stir crazy, Dad's doing well. He's still essentially home bound, but he's continuing to strength train using medical resistance bands, and says he's really toning his core. Way to go Dad! He and my mom have made it out to a few dinners and movies, which is definitely a boost to his spirit and confidence.
Dad's next medical appointment is in early October and he expects to learn more about his prosthetic, including when he'll start using a temporary one and get fitted for his own. Fingers crossed that he'll be ready sooner rather than later!
