As discussed in several threads started recently by our Canadian comrades, central sensitization syndrome appears to be an emerging concept that is already being used as a model to attempt to explain and treat our CFS symptoms. PD White even published a paper on it earlier this year, building a bridge between functional somatic syndromes (which he believes CFS is) and CSS. I was surprised to learn (I don't know why anything surprises me anymore) that the CSS concept has made its way to the USA as well. A user on the /r/cfs subreddit mentioned that they received a diagnosis of CSS from the Mayo Clinic. Mayo has produced this helpful video to explain the concept: While CFS is not mentioned by name, he makes reference to patients with the "push crash" cycle, and "chronic fatigue" is listed at the end as something that they treat under this model, as well as FM, MCS, et cetera. While he doesn't go into depth, the description of their treatment plan at 11:43 in the video sounds basically like CBT/GET to me.
