She was waiting on doctor and Pfizer so she would have two people give her a decision, about second dose. Once they told her not to take another one, she decided not to report it then. The doctor was not the one who gave patient the vaccine and she called him. She was in the middle of switching doctors. (Withheld) was the one who told her not to get it. Six hours after patient got the shot, did not feel right, and can't explain it and never could. The patient just felt odd. The patient stayed same until next day and then patient was on to some other symptoms. The patient had it documented and does not have the paper with her because patient gave it to her doctor. The patient had a fever, and it was gone the next day and then had fatigue. On day 3, patient had Nausea and Diarrhea. The patient did not feel good that day and felt really run down. That did not go away that day. Just the last two days, patient feels like getting back to herself. It had improved a lot. The patient was not doing anything and did not feel right. On day 4, patient just started to get and then corrected to say that on Day 3, had a mild, dull, headache that did not stop her from doing anything, but on Day 4, the headache just all of a sudden, the right side of head right above temple started hurting. It was a terrible headache there for an hour or two. Then the left side of her chest started hurting and also had left side breast pain. Both of those was an all-day thing. It lasted one day and started to develop dizziness. The patient remembered being a little dizzy before that, maybe on 2nd or 3rd day. The dizziness was really bad on 4th day. It was like if the patient used inhaler for cough, the patient would get dizzy from holding breath to use inhaler, or if patient walked. The inhaler was Proair. This was as needed for allergies. The patient usually would do two puffs, and sometimes with allergies now, the patient would use it once daily if the patient gets to coughing a lot. The patient had an irregular heartbeat and did not know exactly when it started. It started in the earlier days in the beginning when the patient was fatigued. It felt like her heart was beating real slow and patient tried to ignore it. The patient could not explain why the patient did not feel right. Sometimes patient still has irregular heartbeat and sometimes it might be beating fast. It was a lot more often that it was at the time of report. It was better. Maybe day 2 was when the patient thinks started feeling it, so the patient was not sure of start date. It was subtle and patient sat a lot and it felt like it was beating slow. It still does it every now and then, but not as much, on day 4 it was worse, but seems to be better at the time of report. Dizziness was gone. The patient has dizziness no matter what the patient did, if the patient walked dog or walked around, the patient just was off. Weakness was worse and yesterday was first day the patient noticed her legs were not as weak and could actually walk her dog. The day before and the day of reporting were completely symptom free, and the patient actually felt like herself. These were the first days the patient has felt this way. History of all previous immunization with the Pfizer vaccine considered as suspect was reported as none. Additional vaccines administered on same date of the Pfizer suspect was none. Patient experienced fever did not feel good and felt run down, irregular heart rate, and weakness in morning, Dizziness in late morning. Fatigue, nausea and diarrhea, mild dull headache in afternoon, severe headache on right side above temple in evening and changed to late morning to early afternoon. Left side chest and left side breast pain in evening and changed to late morning. The events did not require a visit emergency room, physician Office. The patient just rode them out. The patient called her doctor's office but did not go. Prior Vaccinations (within 4 weeks) were none. Events following prior vaccination was reported as Shingles vaccine last year. The patient did not take second one because side effects were so strong. Her chest felt heavy like a bag of sand was on it. It was uncomfortable and came on when patient got home hours later, almost like this one. That was why patient did not want to take COVID vaccine. The patient also had problems with the Pneumonia vaccine the 21 or 22 whatever it was called, the first one. The patient does not remember symptoms. It was 2 years ago. The patient thinks those were just sick feelings, like fever and super sick. They were not severe, but the Shingles one scared her. When patient told doctor and pharmacist that she was scared to get COVID one because of those previous reactions, they said this one was different, and they encouraged her to get it. The patient never had any problem with the flu shot, so decided to go ahead and get the COVID shot. The patient does not have the Manufacturer, lot or expiration for the Shingles or Pneumonia vaccines. Pneumonia was 21Jun2018, and it hit her hard. The Shingles vaccine was on 25Nov2019, and that was the only one the patient got. The patient did not take flu shot last year. After patient got the shingles, patient refused the flu shot. Before that patient was ok with the flu shot and tetanus shot. No further details provided. The patient went to her doctor about something that had nothing to do with the vaccine last week and wanted to talk about her symptoms anyway. The patient was having weakness in legs at that time and was concerned and wanted to have her organs checked, so they checked kidney, liver and organs, and blood work, and all came back ok. It was frustrating to go to a new doctor and asking him how long symptoms are going to last because patient was still having symptoms at that time. He said he had no idea. The patient was still weak and not feeling right and had palpitations quite frequently. He had no idea, stating that it was new, and he did not know. The patient asked if they could be forever, and he said it was possible. That was the most upsetting thing. The patient just tried to spin it on a positive note and said the patient got it on the first and every day The patient got a little less symptom. It has not even been 21 days yet since first one, so every day The patient has less symptoms, and pretty soon they will be gone. It seems for the most part it was better. The patient was still a little pooped out and energy level was not quite there, but it was getting better.  Follow-up attempts are completed. No further information is expected.  No follow-up attempts are possible. No further information is expected.
