I just read a remarkable post (below) that was made just yesterday on a thread from 2003 entitled, "Wrongly diagnosed for 2 years - see real cause". In the original post, the author traced the cause of her FM symptoms to a tight psoas muscle. It's a good example of how a diagnosis--whether FM or many others--is not always a correct one. The story below tells of how another man discovered his own CFS/FM symptoms were also being significantly impacted by a tight psoas muscle. I put his story under the "Sleep" forum, because of his reference to "excruciating insomnia". There's been a number of threads on PR discussing various therapies addressing structural issues and how they've been helpful. I'm convinced they're a large part of my own health picture. Wayne Written by Michael on 8-3-15 "This post change my life ... almost overnight! I had been suffering from CFS for ten years. Like many, I had tried EVERYTHING in the book. I had been told my symptoms were related to early childhood trauma, and had been working with several practitioners on trauma release for about two years, but the symptoms were not improving. I had been suffering a particularly bad bout of CFS for the past few weeks. I had excruciating insomnia, and slept only a couple hours in early morning, and when I woke, it felt like my body had been through war. During the day, I could not focus on the simplest of tasks. A few nights ago, I came across this post about the psoas muscle. I did more research, and learned that the psoas muscle is the primary muscular mechanism in the fight/ flight response (receiving orders from the amygdala), as the psoas muscle is what moves the legs to run. I noticed how much tension I carry in the psoas muscle, and that part of my pattern of CFS was tension in the gut, and difficultly breathing, all related to psoas tension. I looked up some simple yoga stretches for the psoas, and did them before bed. The first night, I slept a full night, and woke reasonably rested. I think it may have been easy for me to begin to correct the psoas tension, because in my past life (before CFS) I was a highly trained athlete. I believe the psoas is the link in the chain between psychological states (for me, the result of childhood trauma) and the somatic/ bodily symptoms of CFS. I have learned so much about this chain (from amygdala to vagus nerve to psoas muscle), and I would be eager to share information with anyone who thinks it might support them. If you would like to dialogue more about this with me, please email me. My prayers to all who suffer from these chronic illnesses. Michael"
