A 54-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, formulation: Solution for injection, Lot Number: EW0196) via an unspecified route of administration in left arm on 25Jun2021 (Time of vaccination: Between 18:50 and 19:00; at the age of 54-year-old) as single dose for COVID-19 immunization. Medical history included ongoing hyperthyroidism was diagnosed just a couple weeks ago (Oct2020). They did a nuclear scan test looking for hot and cold spots (unknown results). It has been almost a month now. They did different tests then checked her TSH (thyroid stimulating hormone) which was off a little bit. That's what prompted further tests. The diastolic heart failure was diagnosed back in Oct2020 and ongoing. They did a Holter monitor for so many days. When they got the results that's what he saw. She is real sensitive to a lot of things. She has a lot of allergies and is not one to respond well to things. She has food allergies and is not one to take medicine. She had diagnosed allergies, compromised immune status, respiratory illness, genetic/chromosomal abnormalities, endocrine abnormalities (including diabetes) and obesity. Family History included Blood clotting issues, Factor V, diabetes, hypertension, heart conditions. Concomitant medications were none. She doesn't take any medications. No prior Vaccinations (within 4 weeks). The patient previously took morphine for food poisoning one time she was at the hospital and they tried giving her Morphine and she had a reaction to that. As soon as they gave her the IV it went straight to her head. The same happened with the Lovenox shot. She had a sensation through her body that was not normal. She was in the hospital at that time and it was a couple years back. She is real sensitive which is why she was so scared to get the vaccine. She was worried about the ingredients. Even diphenhydramine hydrochloride (BENADRYL) she not so much as has an allergic reaction as she is sensitive to the medicine. Even paracetamol (TYLENOL) puts her to sleep. Historical Vaccine included influenza vaccine (FLU) shot last September or October and did fine. Also received levofloxacin (LOVENOX) shot and went straight to her head. She had her first dose of the Pfizer Covid-19 vaccine last Friday, 25Jun2021. Since then immediately she experienced headache, wooziness/ real woozy, extreme nausea that went on for hours and hours. At midnight Friday night it took a turn for the worst. She fell asleep, but the nausea was unbelievable. Saturday morning it started subsiding a little, but the nausea stayed the longest. Sunday was a good day, but then today she woke up feeling okay but as the morning wore on she felt a headache, stiffness in her neck and back, and shooting pain in her left arm from her shoulder down her arm like being shocked. Her arm looks okay. It is a weird sensation, the neck and head stiffness. The shooting pain keeps going. Shooting pain in her left arm up to her shoulder in the arm she received vaccine, and itching in her back. Most of her symptoms started 5 to 8 minutes after she had the shot, so around 19:08 to 19:10. She did call the doctor's office. She doesn't know what the stiff neck and shooting pain are. She asked if these symptoms are normal after the vaccine or heard about before. Asked for guidance for what to do. Stated a lot of it happened when she first got the shot, and she felt worse by midnight then fell asleep because she was so exhausted, but on Saturday the nausea still continued. Stated that yesterday, Sunday, she didn't have problems, but today (28Jun2021) when she woke up she was having shooting pain in her left arm and shoulder, which was the arm she received her vaccine dose in. She didn't have pain before in the beginning, and the headache came back as well as stiffness in the neck. Trying to see if this warrants a medical emergency and it is a concern for me. She is a nurse and had delayed reactions. She wanted to make sure hopefully not too problematic. She is a registered nurse. She works for the hospital and has been there for 30 years. She works on the trauma floor post-surgical. If she sees something happening she takes the smallest dose first. She was worried as they first gave her the shot, and her symptoms got worse and her nausea went to the tenth degree at midnight. She left a message at the office and asked to have someone call her, but they were tied up. She hopes someone calls today because she goes back to work tomorrow. She just has concerns because she knows she is sensitive. Her physician is an attending for a family medicine clinic. She didn't know this existed, she just Googled and found this number. It is all on the left side of her body. The headache started immediately after she had the vaccine. It is associated with the weird sensation in her neck. It's almost like it could be the glands, she can't describe it. The headache came back with her stiff neck and left shoulder pain. She didn't feel it yesterday, but today she noticed it cropped back up. She keeps having a stiff neck like working out and the muscles tighten up in Jun2021. Real woozy started immediately after she had the shot. She was woozy, dizzy, crazy. She couldn't move or drive in Jun2021. It was not cool. That went away, and then this morning it just slightly tried to come back a little bit. Extreme nausea started immediately after she had the vaccine. It was a long haul. She had it all Friday night until Saturday afternoon when it subsided. It comes and goes. She felt it just a little bit this morning. It is northing like the first day. On 28Jun2021 (Today) she had more head and neck stiffness and the left arm thing. The injection site was a little sore when she got the shot, but this is different. That's why she called the doctor. The pain is changing for the worse, and it is different. Stiffness in neck and back, she had it right after the shot. Today she has a headache, stiffness in her neck and upper shoulders, and shooting pain. She can't figure out what is going on. It got on her nerves. It is worse than when it started on Friday. Shooting pain in left arm she just noticed that today on 28Jun2021. That is what worried her. It is all into her shoulder and into her forearm. It just hurts differently. It wasn't doing this. Injection site was a little sore: She had just a little bit of soreness. That is different too. Her arm is the alert for her today. She was working yesterday moving patients and turning and elder person all day. She doesn't know if she could have aggravated it moving and turning. She also had itching in her back. It was an internal itching all on the left side of her back. It was like inside her body, not like a scratch on the skin. It was internal itching. It started immediately 5 to 8 minutes after she had the vaccine. It happened again on Saturday afternoon. It is not cool. It was like in her back and spine. She thinks that might be okay now. She knows some of her symptoms are normal. She just kind of had to throw it out there. It is not life threatening, but she shouldn't ignore it. She is concerned because she is sensitive to so much. She can't answer that right now. She needs to let Pfizer be aware. The shooting pain in her arm keeps coming and going almost like being griped. It is in the should and that whole area. It is aggravating. She was 99% sure the Covid shot caused her symptoms. This wasn't happening before. It is her body's way of responding to this for whatever reason. She is worried about the second dose. She started to go to the ER that midnight, but she cried and went to sleep. The nausea went to the tenth degree/nausea aggravated, and she knew something was going on. She wanted to see if her symptoms have been reported and what she should do or watch for. She wants to know if Pfizer has heard this before and if they haven't she is looking for extra knowledge and guidance. A visit to emergency room or physician office was not required.
