I've been in a cast for a broken wrist for 4 weeks. The cast goes just about up to my elbow. It's extremely uncomfortable, but the doctor just smiled and said that's the way it should be when I told him. Anyway, for about the last 3 weeks, I've been extremely tired throughout the day. I wake up a few times during the night and assume it's because of this stupid cast I have on. Just curious if anyone else got extremely tired after getting a cast on their arm. Thanks.
