Hi Carol,
Just reading thru a few of the last pages of your thread... I can't remember if anyone ever referred you to someone that specializes in chronic pain issues? One of the things that I asked my OS, when it was apparent that they didn't know what to do to help me when I wasn't the typical recovery after THR, was who do you suggest people see when they have on-going issues after THR. I was referred to a medical practice that has non-surgical specialists. They do a variety of types of injections and look more deeply into pain issues from a more global standpoint vs. the just a hip patient view.
Secondly, at some point I was offered medication like Lyrica or neurontin/gabapentin. These medications as well as Cymbalta are sometimes used to help with chronic regional pain syndrome. If there is concern for your morphine usage/dosage then you need the support of someone that has more dedicated experience with medications that might be more helpful in a different way and it doesn't sound like your GP is that person.
Lastly, are you still doing any acupuncture? You'd mentioned it and seeing an osteopath at one point. Just wondering if either of these therapies were or would be helpful again...
Good luck on June 12th with the new OS -- you could also ask him for referral types of information as well.
Take care,
Cardie
