Well the job of a pdoc is not necessarily to prescribe but to evaluate to what extent mental illness is contributing to your symptoms. A good one will consider that this could well be medical illness or medication side effect or both or any combination of things along with some element of mental illness. So it's worth considering. You can ask if there's a pdoc in your area who is particularly knowledgeable about pain or chronic illness.

You are not obliged to follow through with their suggestions. They would just adding information and perspective. If you don't think much of them, you don't have to continue seeing them.

Is there a chronic pain excercise, aquafit or yoga class where you live? Or even art or cooking? It could be a non-drug way to help with things? When I was ill for a long period, I didn't get out as much and classes like that became a lifeline.
