I came across a great book, it has a lot of studies mentioned in it, very scientific, it covers most common pain syndromes, IBS, fibro, Urethral/bladder pain, and much more. I was able to read the first chapter on Fibromyalgia, really good. He mentions a study with a control group and a placebo one where the control group improved on 50 mg of Amitriptyline. Later the mentions some case studies of his own patients. One lady is seen in his office with severe arm pain. After antidepressant therapy (imipramine, 60mg) she improves. He diagnoses her with psychogenic rheumatism. Pretty fascinating stuff, I will try and buy it. Has anyone else read it? I'm especially interested in the chapters on bladder pain and chronic pain. Here are the chapters if you're interested: Part I. Psychosomatic syndromes. -- Fibromyalgia, fibrositis, and myofascial pain syndrome -- Chronic fatigue and chronic fatigue syndrome -- Globus and fear of choking -- Dysphagia and esophageal motility disorders -- Non-ulcer dyspepsia -- Irritable bowel syndrome -- Urethral syndrome -- Behavior-induced physiological changes : hyperventilation and aerophagia -- Chronic pain syndromes -- Part II. Mechanisms of bodily complaints. -- Somatization -- Hysteria -- Deception -- Mechanisms of bodily complaints : main conclusions.
