Hey guys, I was given a CBT booklet a while back from the university of Liverpool, essentially it explained that m.e/cfs is due to an onset of a virus or trauma, but then the body becomes weakened (so much to as short as five days it can start occuring). Which produces weakened muscles, which would explain the muscle pain. And then the weakened thigh muscles which are responsible for a lot of blood being pumped to the brain would cause the profound fatigue and cognitive impairment. Is there actually any evidence based upon this? Sorry if this is in the wrong section or it has been posted before..but I'm just wondering what kind of science is behind what they are purporting.
