You need a new DR. Ask your primary to find out who/where in the USA specializes in your kind of problems and go there. This sounds much more neurological/brain connections than having to do with the vaccine. With the right Dr there might be at least a partial fix for you. A major medical center would have a panel of Drs to review your tests and each bring their expertise to the panel. Sometimes that's what it takes - many brainy inputs.
I've never had a flu shot because it usually mutates making the shot basically ineffective.
I hope you can find a solution and be able to live normally. I wish you the Best Of Good Luck. @marko82
