I got the vaccine last Thursday, March 4, 2021 and I am experiencing strange side effects. I wanted to be sure to send this along to you as well as, to the adverse effect website. It?s almost as if I?ve had a stroke. Initially (after the shot), I was a little lightheaded but as the rest of the day wore on, (say around 6 hours later), I started to get foggy in my brain - like I had to remember to even breathe - and tightness in my chest like asthma. There was a high pitch scream in my ears and I was more or less, kind of out of it. My hands and feet were sweating profusely. My tongue kind of reacted, too and got a little burned, like when I eat pineapple. It was then that I noticed difficulty swallowing. My sister (a medical professional) suggested Benadryl for the mouth and tongue sensation and she kept an eye on me the rest of the night. She also warned that I should not get a second shot (I totally agree). Being a trooper, I thought all of the weird stuff would blow over in a day or two, so I decided to power on and not report my issues.  Today is day 6 post vaccine and I can now see a pattern to the symptoms or episodes which are still present, on and off:  1. The ringing in my ears will intensify, and then I stare off into space, my words get garbled (I have to really concentrate on being present), my tongue gets very dry and then the swallowing issue returns (it?s like slow motion swallowing, so I bite my tongue to stay in the moment).  2. The tightness in my chest intensifies and my breathing gets shallow. I must focus and breath through it despite discomfort. Note, since the shot, I keep a Benydryl and my inhaler with me, although I haven?t used Benadryl since day 3. I used my inhaler yesterday, day 5 because of discomfort and that seemed to help, but using it triggered an ear ringing/screaming episode that came and went the rest of the day.  3. I also have nasal constriction throughout the day. The nasal passage just inflames and then relaxes. I also have phantom smells and my sense of taste got a little off on day 1, but recovered. ________________  March 18, 2021 Update  Saturday, 3/13 went to the ER because the cognitive issues had advanced. I found myself staring off into space, losing my train of thought, and unable to speak. When I did speak I stammered or stuttered. They wanted to make sure I did not have a stroke or that I was not in the middle of one, so they did some tests. They also recommended that I go ahead and take the prednisone.  After my ER visit the cognitive issues continued, but began to be not-so-frequent by Sunday afternoon. I felt like I was on the road to recovery and so delayed again, taking the prednisone.  On Tuesday (3/16), I had what I would call an asthma attack. I was having very strong bronchial spasms that would not abate. I used my rescue inhaler to try to mitigate the symptoms, but that did not work. At the same time, the cognitive issues sort of returned and the big loud ringing and whooshing  in my ears was really really noticeable.  I am having a protracted allergic reaction to the vaccine. I am not normally allergic to things, but I have noticed new allergies since this all began. Certain food items seem to bother me now and push me into the lung seizing, raw tongue, neurological, ear ringing event.
