Sorry for all you are going through! Sounds very close to my story. I am lucky I have a neurologist who believes me and sees many people like me, both post covid infection and post covid vaccination. When I asked her about the Omicron, she was not entirely on board with it, despite my age and risk factors, so I have held off for now. When I asked her about the influenza vaccine, she said "Go ahead, if you haven't had any problems in the past", which I haven't. I have had every vaccination under the sun being a nurse and never had a problem. She believes it is the spike protein that is causing the problems, both in covid and the vax.
