A 65-year-old female patient received BNT162B2 (COMIRANTY; Formulation: Solution for injection; Lot number: EL8982, Expiration date: was not reported,) via intramuscular in left shoulder on 02Feb2021 (Age at vaccination 65-year-old) as dose 1, single for COVID-19 immunization. Medical history included ongoing asthmatic, ongoing allergies, hip thing, diabetes, obesity, respiratory illness and hysterectomy. Concomitant medications included advair taken for asthmatic, flonase and Zyrtec taken for allergies. On 04Feb2021, patient experienced pain, walking difficulty, swelling of feet, swollen glands, tongue disorder, difficulty in standing, calf pain, leg pain, foot pain, muscle pain, numbness of mouth angular, numbness mouth, ankle swelling, pain ankle, muscle discomfort, condition worsened. Patient stated slight numbness in mouth, tongue, and (salivary) glands, similar to an anesthesia after a dental procedure. Her (salivary) glands and tongue felt "different". The symptom was experienced just for one day after vaccination "was slight, but not intense". She reported, a couple days later after vaccination (on 04Feb2021) she noticed that "both my feet, ankles and the inner part of my calf hurt bad, I could hardly walk, the pain is excruciating, I have no clue where that came from, I don't know if it is a muscle, I also have swelling on my ankles. She mentions she needs a hip replacement (the surgical procedure will probably be done in late Mar2021), the leg discomfort experienced after vaccination is different to the pain she usually fells in her hip. Upon follow-up (09Feb2021) she stated she had a slight issue with her glands and on the outside as well as little bit with the tongue on the back half but that only lasted a short time. It was almost like her neck and tongue were tired in those areas, she doesn't know how to describe it. That passed. On the 04Feb2021 she had a flare up, she needs a hip replacement, where she could barely walk. She wonders if the shot had anything to do with her hip but she was astounded at how she could hardly walk. She reported she was administered her first dose of Pfizer COVID-19 Vaccine on 02Feb2021. Starting unknown time when she woke up kind of early in the morning of 04Feb2021 had onset of excruciating pain in both feet and leg muscles down by the calf to the point that she can barely walk. She is astounded at how she can barely walk. Initially she kind of blew this off, thought maybe it would go away. Also, her feet swelled up really bad. When she went to get up out of the bed the morning of 04Feb2021 and put her feet down she automatically had pain when she went to put weight on her feet. She had to sit there and stand there for a few minutes because it was pretty sharp pain. She did not know what happened so when she started to move she was moving side to side walking very gingerly because she had a lot of pain in her feet and side of her legs on her inner calves. She thought once she got changed she would massage it or rub her feet out to see if it helped the pain and swelling; but that did not help; she even put on compression socks but that did not help. She did not go to the Physician's office related to these events; but she already had an appointment with the heart doctor that came up like it was supposed to. She went to see the heart doctor who said she would give her some unknown water pills for her feet swelled up really bad event; but patient told heart doctor she had never had her feet swelled up really bad event before. She coincidentally told the heart doctor she had gone in for the Pfizer COVID-19 Vaccine and what have you. At that time she did not have quite the level of pain in her feet and leg muscles yet. The pain in her feet and leg muscles have worsened; even if she is just sitting she experiences the pain, but pain is especially worse if she goes to stand. She has a hard time standing up which she has never had before. She has an extremely hard time walking which she has never had before. She mentioned with her other condition of hip thing, she still has to move or there will be more stiffness despite the pain in her feet and legs.
