Someone said they describe it like being carpel tunnel, of the whole arm.

Wearing a neck brace while grocery shopping or doing othe errand running when I feel like crap is a good tool, or carpel tunnel splints whichever. People are more helpful, more likely to hold a door, bag my groceries lightly or not give me a dirty look when I ask them to bag my groceries lightly. Or wonder why I make my kid load all the groceries in the car by herself, while I just get in and sit there.
