Kloser, have you considered extended physical therapy? Especially water therapy? Being in a pool lifts the weight of your body off your back, therefore the weightless water therapy you do is less stress on your back, less painful, more useful, longer lasting, and more therapeutic. I spend hours a day in the pool (I have all kinds of back injuries and metal rods and screws holding things together and am in excruciating pain ALL the time, except when I'm in the pool). Of course, this is not a cure or even a long lasting therapy, but any little bits of time you can alleviate the pain is SO worth it. Even still, since I can't LIVE in the pool, I'm on pain meds with a pain management doctor, and that would be my next recommendation. Not being able to *see* an injury or problem In the diagnostic films is, yes, going to be problematic, but the fact is that you can't ALWAYS see the problem causing the pain. If you can find a doctor who hasn't forgotten that part of his/her education and is willing to try some prescription meds as pain management, that's your best bet. You will probably have to shop around quite a bit for a doctor like that, though. I'd try to find a pain management doc and explain that you have chronic pain for reasons as yet undetermined, that you are NOT just looking for drugs, and ask if they can help you with some pain meds and a course of physical therapy. If you show them you are willing to do physical therapy as part of your treatment plan, they may be less inclined to automatically label you as a drug seeker. Good luck and keep us posted.
