Hi whitebeach, and welcome to the TMSWiki Forum!
Most of us here believe, along with Dr. Sarno, that CFS is a TMS equivalent, along with fibro. The thing is, anything can trigger the onset of symptoms that eventually morph into TMS. For example, I crashed my bike and broke my hip in 2008 - an actual structural injury, right? Followed by surgery to insert pins into the femur, so I had to recover from that as well as the break. But to have worsening symptoms two years later, of hip pain, foot pain, dizziness, and shaky legs, all being attributed to the original injury by chiros, PTs, and orthotics specialists - well, it turns out that was all TMS, and a downward spiral of increasing and worsening symptoms was stopped cold by learning about TMS and making a decision to fully embrace that knowledge.
But the initial trigger was a broken femur. Just like a virus could possibly be the initial trigger for CFS. It doesn't mean you have to have a lifetime of symptoms. It's just that your brain has latched on to a weak spot in your physiology as a convenient place to produce symptoms, somewhere where there is a conditioned or memorized response. You have to take charge and force your brain to let go.
Anyway, what we find here is that everyone is different. Their symptoms are different, their associated "equivalents" such as anxiety and depression are different, and what is easy or difficult to tackle is profoundly different. Because we're all unique.
To get back to your specific question, I can personally relate to what you're saying. Not CFS, but my vague non-vertigo dizziness/off-balance/brain fog symptoms are very difficult for me to tackle, whereas pain is not that big a deal for me. I sometimes get pain in various places, but it's never enough to keep me from doing anything I want to do, I assume it's TMS, and it eventually goes away, although it can take a while. I sometimes get headaches and digestive distress, but both of those are quite easy for me to banish quickly, using self-talk and mindfulness techniques that I've learned doing this work. But the vague dizziness - that one seems to be tougher for me, perhaps because it's hard for me to visualize a different outcome. It can totally disappear if I'm engaged in something fun and active, but it often shows up at what I know are conditioned times and places, and it's definitely worse when I'm under stress. It's clearly less when I practice mindfulness more consistently for several days at a time (but I always end up getting distracted again).
For what it's worth.
