That's fascinating, jeff_w, that brainstem compression could cause all the symptoms of ME/CFS, including PEM and severe POTS.
Are you now free of all ME/CFS symptoms after surgically addressing the craniocervical instability that caused your brain stem compression?
Yes. I had severe POTS since 2014, and that is now completely gone. I also had PEM since 2011, and that is now completely gone. Brain fog is gone, too, along with light sensitivity and the many other symptoms.
So a while ago I did some experiments where I applied a substantial force to pull my whole skull upwards from my spine for around 5 or 10 minutes, in order to stretch and elongate my neck (basically I used some household furniture to wedge my head in place, and then used some of my bodyweight as a downward force, sort of hanging my body under my skull).
Your experiment is fascinating for many reasons. Neurosurgeons who specialize in craniocervical instability, which was the cause of my ME/CFS, do exactly what you did: A Traction Test.
They grip the skull and apply traction to see if this eliminates symptoms of brain stem compression. They measure how many pounds of traction are needed to eliminate your symptoms.
During this traction test, the neurosurgeon will ask if your symptoms are being relieved (subjectively), and they also look at objective measures - specifically: Heart rate/POTS & cervical angles.
After this neck stretching exercise, I noticed some mild improvements to my ME/CFS symptoms, improvements which would last a day or two.
Your positive response strongly suggests brain stem compression! Have you ever had an upright flexion-extension MRI sent to a specialist neurosurgeon? If not, I'd strongly recommend this. You could be onto something here.
In my case: It took
30 pounds of sustained traction to eliminate my POTS and PEM and overall ME/CFS symptoms.
The "cervical traction pillows" weren't enough for me. I needed a halo, screwed into my skull, followed by neurosurgery. If you have severe craniocervical instability, you will need neurosurgery to permanently solve the problem.
I wonder if your experience throws any light on the nature of regular ME/CFS? Could some sort of brainstem compression, or perhaps brainstem swelling due to inflammation, be found in regular ME/CFS, causing or contributing to the symptoms?
I actually had "regular ME/CFS" in every sense of the illness. I met every national and international criteria. I also developed symptoms after what
seemed to be a virus(!). I was a true textbook case.
My thinking is this: My autonomic nervous system was disrupted due to brain stem compression. The autonomic nervous system helps control the immune system's functioning. And so, structural brain stem compression can disrupt the immune system, leading to immune abnormalities.
In terms of lab work immune system abnormalities, from 2014 onward I had testing that showed:
- Positive chronic EBV IgM
- Reduced Natural Killer Cell Function
The above markers are classic ME/CFS findings, according to Dr. Kaufman -- the ME/CFS specialist that I was seeing.
However.
Recent research by Dr. Ron Davis is not supporting the "viral theory" of ME/CFS. He's finding no differences between people with ME/CFS and healthy controls in terms of viral markers.
If you look at the
ME/CFS brain autopsies, they found enterovirus infection in the brain stem. Dr John Chia says enterovirus likely enters the brain by traveling along the vagus nerve, which runs from gut to the brain; and this nerve happens to enter the brain at the brain stem (the vagus connects to the medulla oblongata of the brain stem).
Or, it could be that structural brain stem compression leaves the brain stem vulnerable to viral infiltration. Hence, the autopsy findings.
We would need to see these autopsy findings tested on a much larger scale, in order to know how universal these findings are.
It could also be that the brain stem compression disrupts the autonomic nervous system so that the immune system can't clear viral and/or bacterial infections normally.
