A 67-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 2 via an unspecified route of administration, administered in Arm on 13Mar2021 11:13 (Lot Number: Unknown) as SINGLE DOSE for covid-19 immunisation. Patient received the first dose of vaccine on 20Feb2021 at 9:30AM also at age of 67 years old for covid-19 immunization, patient experienced typical side effects later on that same day in the evening, it was a headache, then next day it was a headache and she did have joint and muscle pain, it all subsided. Medical history included degenerative arthritis, seizure disorder which was diagnosed when she was young, hip replacement from 2005, the left hip was replaced in Feb2005 and the right hip was in Dec2005. The patient's concomitant medications were not reported. The patient previously experienced allergic to codeine and Iodine Dye. She received no other vaccines on the same day or the 4 weeks prior. She didn't remember the exact date but she got the pneumonia and flu shot either late 2020 or early 2021, and she was given only half the pneumonia shot, they didn't give full amount and said that the same time next year to get the rest of it. Pneumonia lot probed but she did not have it on hand at the moment. The patient had pain in the right knee, going down into legs, into the foot, and now into the right hip its kind of like all through the right side of leg into hip but more in the back of the knee, like the back of leg down to foot, she has pain in the right knee, due to walking with pain like this and limping because of the right leg, the stress of the strain on the right leg has now caused pain in the left knee. She was also having muscle pain in the right arm, between elbow and the shoulder. The right leg pain started with the 2 weeks after receiving the second dose, the left knee pain started yesterday (as of 12Apr2021). She initially didn't pay much attention to it, she thought it was arthritis, as it came and went with the rain, but as the days went on, she said wait a minute and thought it must be something else. Right leg pain was worse now, she can't walk up steps, she was moaning and groaning because of the pain, it has limited her range of motion now because of this. Investigation included she has back problems, but the doctor will check that when she spoke to the doctor she said it might be sciatica. Patient did not have to go to the ER, she actually already had the doctors appointment annually scheduled already but she did actually contact the doctor to still tell her, because of the pain. Patient took aspirin for treatment but it didn't do much. Aspirin "HEB Brand" lot is WJ04707 and Expiry is Nov2022. The event back problems/sciatica onset date was on an unknown date in 2021, other events onset date was reported as Mar2021.
