Physical therapy isn't always the right thing for chronic pain. When you read about things there will always be good stories and bad stories I guess, so it's about feeling confident in your Doctor. And if they think it has got worse and it is the next option, then just keep asking questions I guess! I don't know if they have them in the US, but I meant more than just pain management, but a specialised pain clinic where they use a range of things from medication, to counselling, to teaching techniques and gentle therapies as well. Would it be worth asking your surgeon about this? ie asking him if it would be worth you trying this before scheduling surgery? He would be able to refer you I reckon if you had the name of a specialised pain clinic. Or he might tell you straight that you are at a stage where surgery is the only option now and it is about more than pain relief. Difficult for you xxx
This kind of thing - I came across the John Hopkins when researching Pancreatic Cancer They seem to be the top place for Pancreatic things. And also have a pain centre.
