I tore off the bandages at 5:30 AM after being wrapped for about 17 hours. My arm and hand swelling had decreased dramatically. Then I went back to sleep. But by the time I got out of bed three hours later, the swelling had returned.
The bandaging clearly works, especially when done in combination with the manual lymphatic drainage. But I think it will take more than a couple of days of wrapping to get back to normal.
