Hi! An update from me - would appreciate your input
I went to London and got the upright dynamic MRI scans. (Traveling to London with ME is the craziest thing I have ever done. But I somehow survived

) My upright scans have been reviewed by a radiologist in London (Francis Smith) and by the neurosurgeon in Barcelona (Gilete).
Both the radiologist and neurosurgeon concluded that I have CCI, AAI and possibly instability down to C5, in addition to tonsillar herniation.
((However, they got different measurements, which I find a bit strange. For those interested, the neurosurgeon reported a CXA of 126 degrees and a Grabb-Oakes of 9 mm in upright neutral (there was no difference compared to the supine mri scans), BAI translation of 4 mm, 7 mm herniation of tonsils below foramen magnum and not much hypermobility. The radiologist reported a CXA of 134 degrees, Grabb-Oakes of 10 mm, 10 mm herniation, damaged ligaments and hypermobility. BDI wasn’t mentioned by either one, so I guess it was normal.))
In the neurosurgen’s opinion I need fusion, probably c0-c5, asap. Based on the objective findings and my symptoms, he thinks I will only get worse and that there is no other option than surgery. He wants me to come to Barcelona for a clinical examination (and surgery).
I find all this a bit scary and overwhelming. I was not prepared to hear that I may need a fusion that extensive (all the way to c5). Also, I’m not yet convinced that my symptoms are caused by the instability. On the one hand, I know tilting my head back and forth triggers a POTS flare, stabbing neck pain and flu/hung-over-like symptoms that can last for many days. On the other hand, I don’t feel like I in general get better with a neck brace when upright, which one would expect. (I realize that it could be because it’s not a good fit. I tried two different types which I purchased online. The first made me nauseous and sick after 10 minutes wearing it. The other one doesn’t make me worse, but I don’t think it makes me better either. I should probably see a doctor to make sure I wear it correctly before I conclude...) Perhaps I need to have a traction test as well...
Another factor that makes me uncertain is that I got sick with ME after a viral infection. I’ve read that infections can cause CCI and AAI, but that it is rare. I guess it could also be that the infection has triggered an underlying (autoimmune) disease affecting connective tissue, or that there’s an underlying genetic connective tissue disorder that made me prone both to infections and to developing instability, but I don’t have any of the signs of hEDS and I’m thoroughly examined for autoimmune diseases...
I would love to get any input and thoughts you (
@jeff_w and others) may have on this. I’m thinking about getting an online consultation with Dr. Bolognese to have a second opinion. I’m also waiting to see a neurosurgeon and a neuroradiologist at a public hospital where I live (although they are not experts).
