One thing that I might suggest that you consider, especially given that docs cannot identify a source of your pain, is of course anxiety . . .but, the other, and I would think that you would need to find a doctor who accepts this condition (even thought the have official recognition) and ask about fibromyalgia . . . the problem is that fibromyalgia, like chronic fatigue syndrome, is usually diagnosed through elimination of other causes . . . I read a paper some place that says that anxiety and depression can intensify the symptoms . . . in any case, I am not qualified either as a med doc or as someone who has experienced fibromyalgia to tell you much about it . . . and, as I say, there are some docs who do not believe these conditions exist . . . . so, you may have to try a couple of docs before you find one that will listen . . .
I could see that Ativan would not ease pain unless it would help you to sleep but that is not happening . . . .and I am not overly keen on meds because of friends who had a difficult time weaning themselves off of them when they no longer needed them . . . do consider a chat about fibromyalgia . . . I am a bit surprised that none of your med docs spoke to you about it (or did they?) . . . do keep us updated and let us know if we can be of any support to you . . . you must be truly frustrated, but do keep asking questions . . . .you deserve an answer and a solution . .. take care, kc
