Clinical narrative: After about an hour following my second COVID-19 Injection I began feeling warm.  My forehead felt warmer so I figure I may have had a slight fever at that point.  I received a metallic (Note I say metallic but I know it wasn't actually metal but that's simply the best way I can describe the taste I experienced) following the injection about 5 minutes after.  My arm remained sore following and still remains sore as of this report.  I experienced a decline in mental acuity following about an hour after injection.  I began to feel lightheaded and exhausted to the point I was experiencing severe disorientation and confusion.  I was having trouble putting sentences together and experienced a ringing sensation in the ears.  I felt like I wasn't even present anymore.  I couldn't comprehend things around me and apparently had conversations I don't even remember having.  Note that at that point I had gotten home but don't even remember getting home.  I just know that this did not begin to wear off until around 8:45pm  when it was like someone flipped a switch and I suddenly was coherent again.  It was an odd sensation to experience.  The arm remained sore and the metallic taste returned briefly after this experience.  I experienced a similar feeling from the HPV injection years ago, but just like this it was a temporary thing that resulted in no long term issues.  However, I cannot tell you fully what we did the rest of the day until around 845-9 pm.  I also remember becoming partly agitated after the injection like my body just all of a sudden took notice of something and shot into action.  I had received my allergy injections this same day about two hours earlier as well and none of these reactions ever occur with those for me.  I continued to drink liquid as far as I know as there were a few empty bottles of water next to me.  I have no recollection of getting them.  It's odd.  There's just this brief moment in time that is just missing from my memory with a few short bits and pieces that are there like a puzzle with some missing pieces.  I feel I became so fatigued I could not function.  My emotions I remember were off and hard to control during this period too.  I felt like I was having some random mood swings.  I feel ok now though aside from the upset stomach occasionally and the fatigue and arm pain (but even the arm pain has partly decreased now).  It all ceased.  I have a number of health issues outside of this but have not experienced this long of a period of almost intermittent amnesia and incoherency following an injection before.  I believe it made me that much more tired or reacted with one of my many conditions or genetic variants that perhaps may have been part of this.  I'm happy to provide anything I can to help with this.  I am greatly appreciative of all the CDC has done to get us this vaccine and continues to do to ensure our safety both before and after injection.  It is commendable.    I did fill out my survey through the V-Safe portal as well and will continue to follow up there should I have any changes.  I have not sought medical care following this event as the coherency and such have seemed to resolve in regards to the vaccine injection.  Only thing left are known side effects at this point besides an occasional increase in numbness and tingling that I already experience in my legs and feet.  My absolute best guess for the cause is my immune system which already has some issues regulating (doesn't always like to learn everything it should and we are currently searching for an undiagnosed autoimmune disorder currently going on as well in me) on top of allergy shots today.  it was perhaps just a bit too much demand on it all at once.  But it seems to be balancing out again now.
