A 34-year-old male patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 1 via an unspecified route of administration, administered in Arm Left on 12Apr2021 (Batch/Lot Number: ER8735) (at the age of 34 years) as DOSE 1, SINGLE for covid-19 immunisation. Medical history included feeling abnormal (cut the circulation off but his head felt like that, felt like this once before when he had a wisdom tooth in the past). There were no concomitant medications. The patient previously took vicodin. Patient received his first dose of the Pfizer COVID-19 vaccine on 12Apr2021 and has not received the second dose yet, stated that there was a delay because he had issues after the first shot. He had issues after his first shot and he is recovered now. He had been to the ER three times after the vaccine. He was never admitted. The doctor said it might be anxiety. He is asking if he can the got second shot and be fully vaccinated since it has been about 4 months since his first dose. On the day of the vaccine, he never got a chance to sit down. He got the shot and was wandering around. First thing was that his left arm felt cold, temperature of his arm was cold. Within 20 minutes his head felt like he was coming off Novocain, not severe Novocain, like at the very end of coming off of novocain is what it felt like. He asked if it was normal and was worried. He then went home and he felt like his right hand was going asleep, it was like a pins and needles feeling which scared him. He went to ER on 12Apr2021. He had high blood pressure and he did not know at the time. The ER did not do any more tests and they sent him home and said the vaccine was safe and was told it was probably anxiety. At night he would feel both his legs go to sleep, like as if his heart was not working as hard. Felt like he had low blood pressure even though he could not check it. He remembers waking up where his face felt numb, like when you sleep on your arm and cut the circulation off but his head felt like that. He may have felt like this once before when he had a wisdom tooth in the past and had Vicodin and possibly got up too fast and almost felt like he was going to pass out. He thought to remedy it since he thought it was a blood circulation issue to wear tight socks and keep his legs lifted up to help with blood circulation, he did this for three nights. He did not go to the doctor at this time since he felt like he was fine. After those three nights, those blood circulation and pins and needles symptoms went away. Then he started to feel chest pain 3 or 4 days after the vaccine. He never really goes to the doctor and was able to get an appointment at a cardiologist and he did a ton of bloodwork. He did blood work in Feb2021 prior to the vaccine and it was all normal. The cardiologist did an ekg that was abnormal and read possible inferior infarct. Cardiologist asked him if he had ever had a heart attack since it looked like he had a heart attack before in his lower heart. Next thing that day was another test where he ran on treadmill, it was a stress test and this test came out fine. The cardiologist said the ekg was probably just positioning since the stress test was fine. C reactive protein, d dimer, and troponin was drawn and it was all fine and low. Next ER visit happened the week that he was supposed to get second shot which he thought may have been anxiety. He noticed his resting heart rate was elevated since the shot. He started wearing a band that was monitoring his heart beat. Felt like he had adrenaline dumps and his heart rate would go up on occasion. He had one of these episodes, one of the days he was working from home and his resting heart rate was 150 beats per min. He felt chest pain and heart beat was high and it was scary. This made him go an immediate care place around 11am, not the hospital. Another ekg which was abnormal and showed S and T wave abnormality and tachycardia. He had elevated heartrate for a long period of time. He was supposed to go to his PCP but he rushed to ER instead. He was diagnosed at the ER as a panic attack. He hyperventilated, his legs went completely numb and hands clenched and he could not move anything and everything was clenching up. His head was clenching up and felt like he was going to die. The ER gave him an anti-anxiety pill that was called lorazepam and he did feel the symptoms subside. He did breathing exercises as well. He felt better and they did a bunch of blood tests. The findings that were abnormal was his magnesium was low, high white blood cell count, and high neutrophils absolute, which is a type of white blood cell he thinks. He was prescribed lorazepam. And was told that an anti-depressant would help but it made him worse and he stopped taking it. He continued for a little bit having these panic attacks where his hands would clench up and the lorazepam would get him out of it. While he was driving, his hands would clench up and have panic attacks while driving. The third time he went to ER was in mid Jun2021 because he had symptoms of a panic attack; his heart beat was very high. He took lorazepam which should calm his mind and heart rate, but his heart rate stayed elevated, heart rate stayed above 120 while he was laying down. They did more blood and heart tests. Ekg was normal rhythm but showed tachycardia. He did a Holter monitor prior to this and only finding was often times of tachycardia, that his range of heart beat would go from 48bpm to 140bpm, all times of the day which concerned him since he thought anxiety would cause this when awake but his heart beat would be elevated even when he was sleeping. Blood test showed his white blood cells and absolute neutrophils were still high but came down. D dimer and troponin was low so there was no heart damage or blood clots. He had an appointment with his regular doctor and was prescribed propranolol, which is a beta blocker, to lower his heart rate. Since the beta blocker, reports it has worked and he has only had to take it once. He has a baseline lab tests with quest diagnostics and his white blood count was normal in Feb2021. A lot of the things that were elevated after the shot were normal back in Feb2021 prior to the vaccine. He has the labs if needed. He was never admitted to the hospital. He does not have the antidepressant to provide details because he only took two and discarded it. Now he is 100% fine. The outcome of events was recovered.  No follow-up attempts are possible. No further information is expected.
