Female Speaker: Chronic pain, Dr. Ferguson. I think when somebody has an ongoing condition don't they sometimes feel like it's on their head or the people start to think it is all on their head? Dr. Todd Ferguson: Yeah, I have seen that phenomenon happen when people are frustrated. We can say a clinician, a doctor is frustrated that my treatment just that I working, they need started to think, well, it is may be just them, you know, because I'm just so frustrated or if a patient started to think that too, and nothing seems to work may be I am just making this out, but very rarely, do I see people malingering or actually making it up unless they are trying to do something for an insurance claim or something like that. Female Speaker: Okay. Dr. Ferguson: Usually, it's real pain and even if you can't find anything on lab values, you can't find reasonable explanations for it. That doesn't mean that not experiencing pain, which is means I haven't found the cause or I haven't found the reason for it. You see you know things don't always show up in labs. They are there to assist us but they are not everything and so I think majority people are really experiencing pain and anyhow some with yes in their head, because what's in our head affects how we feel. When I am depressed and more likely do feel more pain and that has to do with you know neurotransmitters and chemicals in our brain. So, you know, your body can affect your how you feel and how you feel it can affect your body, mind-body interaction. It is a very real thing. So, I think to say it's all in your head is really very true, but yeah of course, some of it is in your head because you are a person that involves the head. Female Speaker: Okay, well put, thank you.
