Brief Answer:
Not exactly sure of the question.

Detailed Answer:
ok... getting injured will literally jangle the nerves.
Reasonably if someone has had a series of injuries then there can be neurotrauma that will cause pain.
I think that giving anti-depressants and believing someone is entirely legit are not separate viewpoints. Here are a few of the things anti-depressants do:
1) they help depression which makes pain feel worse
2) they often have direct action on the nerves and spine that lowers pain directly
3) they down regulate the jangle. About the only thing that does.

Then, it depends on the actual source of pain and the type of pain for more detail. AND, sorry, but, there's the obvious addiction issue if someone is on narcotics BUT there is the BIG addiction issue that I am telling you specifically because I think it is the most important thing here in that many nerve jangle conditions are 1) real 2) might not be treatable and 3) I want you to realize this is the most important thing personally I have found of importance in my daily life and that I value you.

The parts of the brain involved with addiction automatically give an internal dialog. It is a reflex. It is not necessarily to be believed much.

Example. Every time I exercise it says I must quit, "I don't need to do this". and, actually I do need to exercise.

So, the nerves are jangled from operations and injuries. There really is pain. There is a reflex that will automatically as a protective measure cause you to not fully move to minimize the potential for pain. This gets in the way and accentuates pain and decreases mobility. Physical therapy can be helpful; aquatherapy is uniquely good at it. Narcotics tend to make this reflex worsen but they don't have to and they are not automatically bad.

I hope this is helpful
