Very rairly do I ever take care of a patient with cronic pain that I truely believe is having pain. When you ask most of these patients what their pain is on a scale of 1-10 they will often say it is an "11 or 12" while they are talking on the phone eating a sandwich. Now there are definitely patients who I have taken care of that I truely believe are having pain but they seem to handle it differently, they are still active in there own care for the most part and tend to have a different personality. The ones I believe will also usually rate their pain as a "6 or 7" because they truely know what pain is. If you look at the majority of patients that say they have chronic pain they usually have crappy coping skills, f'd up family lives and support systems, many times they are overweight and they often times don't want to change anything. The majority of times when I have true chronic pain patients they usually have great personalities, good coping skills, strong support systems and they are a joy to take care of. And yes, most (not all) of the time they have something that is medically diagnosed and not just a label like fibromyalgia. I don't know enough about TMJ yet but I do know that I once had a girlfriend who wouldn't give a BJ because it "hurt my TMJ" and she had a crappy family life, poor support system, poor coping skills and other chronic pains that she was free to talk about.
