How many definitions for pain signals are out there? It doesn't stop and I have to be really honest here, it all sounds like hogwash for a person who was unstoppable and prior to her injury had the stamina of a bull (as a friend once described me).
Its limiting living in a birdcage!!! But when you are injured, unable to work, need to rely on a system for money, you don't want to risk losing your only source of income. So you sit, gagged, locked up, don't attempt or try anything and that can be most damaging. How did I survive in the birdcage?
