A clinician or therapist should be able to help you. They must understand pain themselves and be able to explain it to you, making it personal and giving meaning to your lived experience.
One is pre-existing beliefs: eg/ possible causes, the types of things that will relieve it, the types of things that won't, how much influence you have, other people fix me etc.
These are all conditioned, so no blame.

But some may be right and some maybe wrong.
The more we hold onto them without considering other possibilities, the more we may be following the wrong path.
