This consumer reported similar events for two patients. This is the first of two reports. A 40-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot number: EL8982), intramuscular at left arm on 21Jan2021 15:38 at a single dose for COVID-19 immunization. Medical history included Tachycardia (started about 4 years ago), Hypertension (started about 4 years ago) and Essential tremor from 2020 (she has been having symptoms for a while; finally, during the summer of 2020, she was diagnosed through a neurologist) and anxiety, all ongoing; pain, back problems and sleep disorder.Concomitant medications included ongoing Tizanidine as muscle relaxant for back problems, ongoing Metoprolol tartrate for hypertension and tachycardia, Primidone for Essential tremor and ongoing Clonazepam for essential tremors, to help her sleep, and also for anxiety. No prior vaccinations (within 4 weeks). The patient got the first COVID vaccine dose. Afterwards, she went to school and it "was downhill from there". 5 days of persistent symptoms including sweating, muscle pain, joint pain and left hand swelling. It was further reported that she had to wait 15 minutes and then she drove home which is about a 35-minute drive. So about 45 mins after receiving the vaccine, she noticed her tongue, it was more on the right side of her tongue, she can't explain the sensation. She couldn't really taste. Things didn't taste right to her. This lasted 24 hours. She woke up the next day, 22Jan2021, feeling not quite right. She took some Tylenol that morning and went on into school. She took some ibuprofen in the middle of day, it wasn't a big deal. She has a history of tachycardia, but her pulse kept reading normal. She had a drink she was drinking from lunch and she ended up having the remainder of it the last few hours of that day. At about the end of her workday, around 15:30 she was finishing the Cdrink off and she said to herself "oh that taste like a regular drink again". This tongue sensation/lack of taste resolved. At that point, she got really excited because she thought this was all that she would experience with the vaccine. She was grateful she had the chance to have the vaccine. She mentions her arm was very sore right off the bat. She experienced immediate soreness in her arm right after receiving the COVID-19. She thought when they were injecting her, it hit her bone. In fact, she joked about this with the person administering the vaccine. The person at the facility told her to rub it, it actually helps with that. This kind of soreness didn't seem like a major problem. She was still experiencing this soreness. If she is sitting on the couch sideways, with her side of her arm against the couch, she has pain that extends up into her neck. It was pretty painful. Friday, 22Jan2021 (24 hours later after receiving the vaccine), by the time she got home from work, she was really sore. She had some real muscle pain around her hips and upper thighs, both of them. The soreness extended across. It was like she had inflammation that started flaring up. She felt pretty sore that evening. It wasn't like a normal muscle soreness. She went to bed because she was pretty tired. The next morning (Saturday, 23 Jan 2021), she couldn't get off the couch. She had such bad muscle and joint pain. She slept off and on, the pain was pretty bad. Her whole body had so much stiffness and inflammation. Every muscle and every joint just hurt. She confirmed that she hasn't been able to regulate her body temperature. This has been going on since Saturday evening (23Jan2021). She stated that this wasn't normal for her. She does take medications to lower heart rate but she hadn't taken it. She was talking to her best friend about how she had been sore and slept all evening. She checked her pulse and it had dropped down to 40. Her O2 level was at 92. She didn't think it was that big of a deal. Her best friend was kind of freaking out about it. She had such pain and stiffness in her chest that extended across her shoulders, it made it difficult to breathe. She was laboring to breathe. She checked her pulse thinking maybe she was feeling anxious about it and her HR was up, but it wasn't. She states happened so bad yesterday, yesterday was worse than before. She got up on Sunday morning, 24Jan2021, and took a hot shower. When the water from the shower head hit her chest, clarified as her upper chest muscles just below her collar bone, the pressure of the water hitting her was painful. However, she was able to get up, she was moving around. Still the whole time. she had this fever-ish feeling. Her kids were telling her that they were sweating because she had the house at 76 degrees. Monday morning, 25Jan2021, she woke up and she was itchy around her left forearm. She was really itching on Friday night, but she didn't think anything about it. When she took a hot shower yesterday (25Jan2021), a red rash came up on her chest and it looked like she had hives on her forearm. She didn't know if the hot water flared that up, but she doesn't have any allergies. She also had gastrointestinal issues. She has had some nausea that has lasted the entire time since she received the vaccine. She clarifies the nausea has came and gone. She hasn't had much of an appetite. They thought she had a fever yesterday at school. It was 99. something but she had already taken Tylenol a couple hours before and she was sweating so much. She states she has also had diarrhea the last few days, clarified as the last 2 days (24Jan2021). She has already spoken to someone to report her symptoms but wasn't sure about and had question about getting the second vaccine dose. She reported having gone to Urgent care where she was told she had Post covid vaccine syndrome and that she shouldn't have a problem with the second dose. She explained she went to the urgent care yesterday, 25Jan2021. She called her doctor that morning and was told to continue to treat her symptoms and take ibuprofen and Tylenol but if she got worse, to go to urgent care. So, she went to the urgent care (Product information for the Tylenol and Ibuprofen she has been taking (Ibuprofen: UPC/NDC: not provided when probed. Lot: P142385 Expiry date: Apr2023 and Tylenol: UPC/NDC: not provided when probed. Lot: P121664 Expiry date: Sep2023). The nurse just explained (Name Withheld) was having the same exact symptoms as the patient, except it was (Name Withheld) second dose. Her symptoms were identical to the patient. The patient wasn't initially sure if it was from the vaccine or if it was her anxiety. The patient didn't feel anxious and her heart rate wasn't up. The patient told she didn't think anxiety caused her to feel like she had a fever. The school nurse looked it up and found out more symptoms kind of wax and wane. Her symptoms got much worse. On 25Jan2021, Test: Rapid COVID-19 test Result: Negative. The event immediate soreness in arm was not recovered; event couldn't really taste, things didn't really taste right to her recovered on 22Jan2021 and nausea recovered in Jan2021; and unknown outcome for the other events.; Sender's Comments: Linked Report(s) : US-PFIZER INC-2021101606 same reporter/drug, similar events, different patient
