This is a fascinating article. The study of TMS is my TMS. That said, I have an open question about this part:
The first is that if inflammation can cause what we recognise as depression...
This statement does not fit my personal experience. Without going into a long debate, colds (sore throats, laryngitis, URIs of all kinds, etc) are a TMS equivalent symptom, at least in some of us. The statement that inflammation causes depression has also been made in a number of medical research papers. I've noticed that I get colds much less often than I used to after learning about TMS, and they never anymore have association with other sick people, the season, atmospheric humidity, on and on. Colds are a fear reaction of intermediate intensity, at least for me. They've always been. I even had a dream about it that told me precisely that. The brain/mindbody knows how to quietly eliminate a respiratory virus without you feeling a symptom, just like it doesn't ordinarily give a shit about a herniated disc, with accurate understanding and low enough fear, rage, etc.
My time course has been: something unexpected makes me afraid; the first thing I notice is a sore throat (laryngeal tension); if the fear is intense/overwhelming the cold "blooms" into the usual cold symptoms lasting a week or two. By the second half of the symptoms, I actually feel great emotionally. I feel happy, peaceful, hopeful, more loving than usual. This is when I am coughing and hacking up green snot. It's green because it's full of mixed inflammatory cells and sloughed respiratory cells, coming off from inflamed airway tissues at some anatomical level(s). Visual proof of inflammation that anybody can see easily. So I would say the opposite of what this article says on this particular point, Depression (or other unpleasant emotions) causes inflammation. TMS theory might say the cold is a distraction, a psychological defense.
Has anyone else had this experience? This may be too personal, but like Jan, if you recall the last time you had an RA symptom, did a specific emotional reaction precede the symptom? How did you feel subjectively after the symptom was established (i.e. some sort of visual evidence of joint inflammation was present) and then began to abate? If anyone else has experienced this, why might it be so?
