I have been going through some crazy symptoms since having Covid last year. I have been through every type of test and doctors couldn’t figure anything out. Aunt Jessie was here to aid in my anxiety and questions as I was panicking for a long time. My symptoms all started after Covid and a random sexual encounter where I developed joint pain, burning “pins and needles” pain all over my body, blurred vision, memory issues, etc. finally one doctor tested me for Epstein Barr syndrome “EBV”. My tests came back positive showing I had a current active infection. Out of all 15+ doctors and specialists, a blood doctor finally told me he heard of bizzare issues coming from ebv. So I joined an EBV page, and have been learning so much. One person who has gone very deep into this disease is Anthony William. Who actually published a book on it. Look up his ebv video and it will go over pretty much every single symptom you just mentioned. He wrote the book Medical Medium and you will have answers to all of your questions if EBV is the culprit.
Nobody really knows much about it, everyone will tell you it has nothing to do with your symptoms unless you have immune suppressing diseases already. But little people know that there are some very series variants of the disease that can literally kill you if not taken care of in time.
I would watch the video, ask your doctor to get tested for the antibodies. And go from there. Doctors really can’t do anything but you can change your diet to help you. I’ve been listening to his book and have started seeing good progress already!
If you do get a positive result (95-98% of the adult population has at least 1 strain of ebv) join the “stuff that works” website group and people will be there to support you.
I'm not sure why you think it's vaccines causing this, but have you asked your doctor about that possibility?
I'm sure it's really scary, but try and remain positive. It may end up being nothing like the first doctor thought. :)
I'm going to ask the mods to move this to neurology so it's better categorized.
