A 42-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE), via an unspecified route of administration administered in left arm on 22Apr2021 (at the age of 42-year-old) (Batch/Lot Number: ER8735) as UNKNOWN, SINGLE for covid-19 immunisation. It was unknown if patient was pregnant at the time of vaccination. The patient had no relevant medical history. Concomitant medication included multivitamins. The patient stated, "So, in chronological order I got the vaccine on April 22. Okay So, my first symptom that night on April 22 was headache, then on April 23rd Friday, I had symptoms of shivering body, headache, warm eye, just feeling like very bad cold or flu like. Then on Friday night to Saturday, so you can chronologically, April 24, 4 am I woke up to a very neauseal senation and feeling that I was going to faint which scared me a lot, I was supposed to go ER, but I didn't, I just you know calmed down, given it was 4 a.m. in morning and don't want to scare my family and that was very scary symptom. April 25 I felt my lymph node swollen and ever since April 24 I had dizziness. So, I would feel dizzy from time to time particularly in the middle of the night like 4 am that's when I felt the dizziest. The nausea was very very persistent like I felt like I needed to throw up but I didn't on the 24 of April but then on 25th and onwards I continued with dizziness felt without nausea just being dizzy. On Tuesday April 27, I started having a rapid heartbeat palpitations and that started scaring me even more. So on Thursday April 29, I started feeling sensitivity in my veins like I could feel pulses in my veins in my whole body along with raising heart beat along with heart palpitations so I went to a minor emergency room provider. They told me I had to hydrate properly, rest, not exercise and to allow for the vaccine to make it through my body because the symptoms that last up to two weeks and they suggested that if I still felt like I was gonna faint, I have to visit the emergency room. Fortunately, I didn't have to visit the emergency room but my heart palpitations, my regular heart palpitations have continued. So, I am now on beyond my 2nd week and today I scheduled the call with a cardiologist because I have a heart, you know pulse monitor, pressure monitor that takes your pressure and I wear a fitness watch and I can see in my fitness watch how my heart reaches over 120 palpitations. So, I scheduled with cardiologist for next week Tuesday and the dizziness has gone away for the most part. It's incredibly minor if I feel it but at times I feel it. But I don't like irregular heart beat and last night my pressure monitor told me, detected it because you have to detect it at right time, it's not all the time but the monitor was able to detect the irregular heart beat at 79 pulses and my regular heart beat is more like 64." The patient also stated that her doctor told her that what she was feeling her vein was reaction to her nerve system from the vaccine. So he suggested that she soak in bath tub salt, which she have been trying to as best as she can but that really was relief like she don't have feelings of sensitivity in the vein anymore the only thing that continues was regular heart beat. The patient took only Tylenol 500mg, one capsule every 6 hours, orally for the headache and after headache was gone, the patient stop taking Tylenol and then she have been trying soaking in of absence salt and she have been trying to drink plenty of fluids among which includes beverages with electrolytes. Therapeutic measures were taken as a result of headache, flu, and "feeling sensitivity in my veins like i could feel pulses in my veins in my whole body." On an unspecified date, the patient recovered from headache and "Feeling sensitivity in my veins like I could feel pulses in my veins in my whole body" and was recovering from dizziness. The patient had not yet recovered from irregular heart beat while outcome of the rest of the events was unknown.
