I don't think he was saying you're not in pain. Fibromyalgia is a painful condition. In order to even give the diagnosis you have to have pain in so many joints so I'm pretty sure he believed you are in pain. I'm a little confused about what you wanted. It seems like usually you are complaining that you don't want drugs or surgery or anything. You can check on the Fibro forum, but from the people I know who have it they usually aren't given narcotics for that dx. That's not to say you don't need methadone for your other issues, just that the best treatment for the fibro piece maybe is OTC meds and behavior modification (a former co-worker of mine had to be very strict about her activity levels & never, ever go even just a little over what she was allowed to do. her husband & kids had to help her even with the simplest things like carrying in the groceries or hanging a picture on the wall. it was super tough on her to make those changes, but after a few years & a short while on Lyrica, she was able to return to the workplace & prepare meals like she always used to love to do pre-fibro. once she got her routine down, she really was only taking Motrin to manage her fibro symptoms). The Fibro people really could tell you better; I just think maybe you need to find out what the normal treatment is before you decide whether or not to try the doc's advice.
Only you know what you want out of a doctor, but I think at some point you need to decide what you are & are not willing to tolerate in your doc and stick with it. I do wish that all of us could have perfect doctors all the time, but that's not too likely to happen. Even the best docs have bad days. I know I get into arguments with my PM b/c one day he'll tell me to cut back on activity & just take more meds, then the next visit he tells me I should have tried to cut down on the meds on my own and be more active. I put on my angry face & tell him he's just completely confusing, and sometimes I even go home and write hostile letters to him cursing him & his family (which I promptly shred almost as soon as I finish writing them), but at the end of the day, he really does quite a bit to help me so I am willing to put up with his crazy moods. After all, he has pain problems himself & that is both a blessing and a curse. On the upside, he better understands what it's like to be in pain. On the downside, when he's in pain he gets as short-tempered as I do when I'm in pain and sometimes that spills over into my appointments with him. But best of all, he puts up with my way over-the-top anxiety about sedation/anesthesia and I know most pain docs would never tolerate such a severe phobia. So I keep with him & most of the time I'm pretty glad I have. :)
If you are written for a Xanex & a half, then take them. Regardless of whether you keep or drop any or all of your doctors, there's no reason to suffer with stress & worry. Do take care of yourself & try to feel better. Maybe take some time do work on one of your paintings. Or write a poem (I always love your poems). Just something low-stress to get your mind off things. It will be okay. I promise. :)
