I can't tell you anything about my experience at OHSU's nerve center, because I have not been yet. I'm in the process getting to see them. OHSU is in Portland and I live on the coast and have not been seen at that hospital so there are some hoops I have to jump thru. Their neurology department (which the nerve center is part of) is well respected and the entire hospital is in my insurance's network. They seemed an obvious choice to start with this.
One of the things they claim to be able to do is too diagnosis when any nerve issues you are having are autoimmune in nature. That's important here, (and it's what I meant when I said sort out) because the chronology of how the nerve pain has involved with me suggest there could be a strong autoimmune component. Achalasia, which seems to have always been related too, is my third major autoimmune disease. My recovery from the surgery was definitely completed by the three Covid vaccinations (as well as a flu shot). They just made everything worse.
Under normal circumstances I would have never taken that many vaccinations in such a short time (especially not after a surgery), but with the pandemic I felt to have no real choice. Above everything else if a vaccine can cause an adverse reaction like this it's a safe be the virus would be far worse.
And that's the main thing I'm looking to understand, because if this pain is autoimmune in nature, it has to treated a bit differently. And I'd like to know, so I can take better precautions if any more vaccinations are necessary.
