Don't know why, but I haven't been able to get feeling in feet and hands nor get rid of severe neck pain all day. Usually takes a few hours, but I've done it all ... the meds, exercises, stretching, etc, and it still wouldn't be physically safe to go out. Walking the dog was risky enough.
These are physical things, but I'm sure the bipolar interacts. And I know the bipolar worsens with age.
