Clarifies did not receive Pfizer COVID Vaccine until 18Jan2022. Is having a better day. Has been a real long road to get here. Still not feeling like self. Clarifies has not spoken to Pfizer regarding symptoms had after receiving Pfizer COVID Vaccine.

Within an hour or less of getting Pfizer COVID Vaccine felt almost immediately a warm sensation. Probably not a big deal. Felt something moving though. Had no pain at injection site. Just felt like equilibrium was a little off. Had a little bit of panic, panic is not the right word. Told pharmacist who administered Pfizer COVID Vaccine about past health concerns and pharmacist did not care. Was sitting a little bit after receiving Pfizer COVID Vaccine, feeling a little off. Pharmacist did not look or examine just asked if there was inflammation at injection site and told caller to go home and take a Tylenol. Was with wife. Got to car and did not feel right and needed to go back in administration site. Something was just off. Felt like was walking strange. Couldn't quite hit ground normal. Said nothing, pharmacist could see to go home and take care. When getting in car had tremors really bad. When leaning back while wife was driving, felt like falling. Progressed into much more, so many symptoms. was hard to breath, felt like being electrocuted, and like broken glass through veins. was told had anxiety. Has never had where went to take blood, things this occurred but was a little bit blurry.Feeling like being electrocuted: Took blood or something and blood shot out, was insane. Blood pressure must have been going crazy but doesn't know. Never felt that kind of feeling.  Suddenly knuckle was killing in right hand: Dealt with symptoms before going to hospital as well. Symptoms were very randomized and got worse. At birthday gathering, all of a sudden knuckle was killing in right hand. Never had this problem before. Was really weird. Felt like heart was going to start racing. Had to get away from everyone. Before know it was getting shooting sensation in left hand all way up into chest. Thought was having heart attack. Has never had a heart attack but was guessing. Had pain and pressure electrical, shoot from left arm up to left chest. Could write a book with experiences, weird. hard to breath: Began shortly after receiving Pfizer COVID Vaccine. Clarifies did not begin the same day received. Is not as severe now. Got worse as time moved on, was not 24/7. Sometimes still has shortness of breath. Thank God is doing a lot of neurological exercise with therapy doctor and has calmed down. But this is 8 months out. Was happening daily for longest time. feeling like being electrocuted: Began days or weeks after receiving Pfizer COVID Vaccine, somewhere in that range, can't be 100% certain. Have weird freaks episodes every now and again. Was a different sensation then. Was literally on floor kind of on knees couldn't move and felt like middle of trunk, abdomen was paralyzed and absorbing energy. Don't know what was doing. Now, when happens is more like a buzzing in legs and hands. then accompanied by racing in heart and high blood pressure. Worst documented blood pressure was 171/90, which is not normal for the caller. Clarifies the blood pressure was 171/91 but could clarify with office on record at doctor's office. Even if caller was a little nervous, something going on bad in conversation, blood pressure elevated slightly but never 171/91.Broke glass through veins: Has had a couple of relapses and with other symptoms of broke glass and zaps. Felt like acid in veins, blood was acidic. There was tearing in muscles. Thought nerves were being attacked. Does still happen but is infrequent. At one point happened daily. Lyme's Disease: At one point was supposedly diagnosed with Lyme's disease. Mentioned this to pharmacist prior to receiving Pfizer COVID Vaccine. Was diagnosed with Lyme's Disease in 2017. Is not 100% certain diagnosis being Lyme's Disease. Is only diagnosis caller has received from symptoms had prior to receiving Pfizer COVID Vaccine. had reason did not want to, was worried about getting Pfizer COVID Vaccine, about something else being at play. Figured will look at medical record. Is worried that anything like Lyme's disease will discredit situation happening to caller. Clearly, did not have any of symptoms caller had prior to receiving Pfizer COVID Vaccine. Neurologist ran tests and other complications might have related to Pfizer COVID Vaccine but does not know. Everything cam mimic Lyme's Disease. Before knew had Lyme's Disease looked up and basically could have had Guillain Barre and MS you name it. Don't know what happening. Before3 received Pfizer COVID Vaccine wasn't dealing with symptoms. Doesn't want existing diagnosis to pass blame. Dates of hospitalization were either 30Jan2022-31Jan2022 or 31Jan2022-01Feb2022. A month ago was flipping 1 and 0 numbers in brain: A month ago was flipping 1 and 0 numbers in brain. Couldn't even find paperwork. Maybe brain is dealing with so much in general, flying out of brain. At beginning could not read sentence and retain what was being read, like brain damage, was weird. Words were jumping off page, so blurry and overwhelming. Wife did paperwork before things got better. Could sign name and that was it. Had to ask wife to read things and couldn't do it. Had to take breaks in between. Was messed up, didn't know what was happening. Is getting better. Sometimes, knows what is up. Is not here to blame Pfizer COVID Vaccine  Follow-up attempts are completed. No further information is expected.
