feeling a little weird; Nauseous; Headaches; blood pressure went up over 220; pulse rate went way up; really ill; memory is a little off right now; felt like I am going to faint; ringing in the ears; dizzy/light headed; a really really sore arm for two days after the vaccine; allergic reaction; This is a spontaneous report from a contactable consumer, the patient. This 77-year-old female patient received the first dose of BNT162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; Lot Number: EW0171), via an unspecified route of administration on 29Apr2021 (at the age of 77-year-old) as a single dose for COVID-19 immunization. Medical history included allergies and sinus headaches which she takes (Excedrin) off and on for years in the past, and high blood pressure. Concomitant medications included atenolol (manufacturer unknown) taken for hypertension, start and stop date were not reported. Past drug history included the patient received a flu shot (unspecified Flu shot) with a mega reaction she was sick for weeks which was at least probably 15-20 years ago So, she never got a flu shot after that and she has never had the flu. On 29Apr2021, the patient had a really really sore arm for two days after the vaccine, dizzy/light headed, felt like I am going to faint, and ringing in the ears. On an unspecified date in 2021, she experienced allergic reaction. On 01May2021, she was really ill, and her blood pressure went up over 220 and pulse rate went way up. On 02May2021, she experienced headaches. On 06May2021, she was feeling a little weird and nauseous. On an unspecified date in May2021, her memory is a little off right now. The clinical course was as follows: the patient reported, "I had a really really sore arm for two days after the vaccine, it's okay now, I couldn't really move it. I feel I may be having a severe allergic reaction to the Pfizer vaccine (Pfizer Covid-19 Vaccine) got on Thursday (29Apr2021) of this past week. I am very light headed, dizzy and felt like I am going to faint, has ringing in the ears, and all that has been going on about a week, since last Thursday (29Apr2021). Then I was really ill last night (01May2021). It started last night when we went to bed around 11 O'clock. I have never had anything like this in my life. My blood pressure was through the roof. With a blood pressure cuff and a stethoscope, her blood pressure went up over 220 which was so high that had never happened before, so I took an extra pill (atenolol 25 mg tablet) last night (01May2021) which helped a little bit but not enough, and I really thought that I was going to pass out and be really sick. Because I thought that it was either having a stroke or a heart attack, my husband had to call ambulance to take me to the hospital last night. The systolic and diastolic and pulse rate went way up.  They did chest x-ray, blood work, and urinalysis, and everything came back fine and they could not find anything. They just felt that I was just having a major reaction to the shot so they sent me home. I just got home this morning (02May2021) from having to go to the emergency room. But as soon as we got home, I started with a humongous headache and so I had Excedrin/Tylenol for headaches because I used to get sinus headaches. So, I took that, and it helped a little bit, my headache got a little better. Anyhow, I am much better right now and I am sleeping. But tomorrow it will be the same." Later the patient also reported, "Today (06May2021) I am feeling a little weird with ringing of ears and is light headed sometimes. Because of the light headedness, I feels a little nauseous. But I am a still very nauseous. I feel like I am going to faint again and my blood pressure I think has gone back up. I am trying to keep calm and trying to figure out what is going on. But I am really afraid if I am having a reaction to the vaccine unfortunately. I am dizzy and I do not want to start getting worst again. I guess I will feel better if you tell me that this happens sometimes and what can I do to decrease somehow?" She also stated that she did contact her doctor about this event but she didn't get very far. Her memory is a little off right now because she really has not felt well. She stated that her biggest thing is her blood pressure. She also stated, "The only thing that I am really concerned now is about getting the second shot because I already had the reactions by the first shot. Am I going to face the same thing or even the worse with the second shot?" Treatments were received for her blood pressure went up over 220 and headaches. The clinical outcomes of the event "a really really sore arm for two days after the vaccine" resolved on 01May2021, the event nauseous was not resolved, while the events, allergic reaction, really ill, felt like I am going to faint, pulse rate went way up, ringing in the ears, dizzy/light headed, Headaches, feeling a little weird and memory is a little off right now were unknown.
