I had two concussions 3-4 years ago. One of them I had lingering headaches and weird issues from. I was diagnosed with “post concussion syndrome” back then and saw a neurologist for a few months. My symptoms mostly subsided but I’ve always felt like there was some dormant issue in the area where I hit my head. I would still get pains there every so often when I was super stressed out or dehydrated. After my second Covid vaccine back in April I had one of the worst headaches of my life for 2 days then was still sore in that spot for weeks. It seems like I’ve had intense brain fog since them and flare ups in that area more often. Anyone else with similar issues? A post about this I tried to make in a post concussion syndrome group on Facebook was denied by an admin which is frustrating. I’m not anti vax but I don’t think it was tested on people with TBI or post concussion issues. Theoretically it makes sense that the extreme inflammation from Covid or the vaccine could potentially cause lingering symptoms from brain injuries to flare up again. Just curious if anyone else has had a similar experience…
