She is out of breath when she is talking; Can hardly take the pain/all muscles seem to be hurting/things really started to hurt in the group of muscles; She started getting bad/shw was awful/she thought she was dying; Vaccine in the right arm, which swelled up for a while; Pinched nerve under my arm sometimes/she has pinching nerves too underneath her arm underneath her underarms; It will go numb (both arms); This is a spontaneous report from a contactable consumer (the patient). A 59-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection), via an unspecified route of administration, administered in right arm on 24Mar2021 16:45 (Batch/Lot Number: ER8727) as single dose for COVID-19 immunization. Medical history included ongoing spinal stenosis (is in the very bottom of her back and she had three back surgeries, one surgery in the middle of her back, one is the neck and one on the bottom of her back and this is years in the making), ongoing diabetes, fall on 01Feb2021 or 29Jan2021, she fell and her arms were outside and caught her fall and the underarms hurt and she fell onto her breast hard; according to the HCP she had a look and said she pulled the muscles and this is ongoing. She stated that the muscles would be across the top shelf of her breast above the start of cleavage and under her arms on the outer sides of her breast, underneath her shoulder blades and to her spine things are getting better but she was not perfect and is still hurting and now is lucky if she can reach to grab her diet soda; overweight from an unknown date, and tooth infection from Mar2021 (probably about 6 days before getting the vaccine and is taking Clindamycin 300mg capsules and takes it three times per day). There were no concomitant medications. The patient stated she had the first dose of the vaccine on 24Mar2021 and she is supposed to get the second dose on 07Apr2021. She stated she had the vaccine in the right arm which swelled up for a while (in Mar2021) and next day was fine. By Saturday (27Mar2021) things really started to hurt in the group of muscles. By Sunday (28Mar2021), she could hardly take the pain and went to the HCP on a Tuesday. The pain totally changed. All muscles seem to be hurting, pinched nerve under her arm sometimes. Sometimes it will go numb (both arms). Above T11 and 12 by 1 or 2 places that it would go numb. When she lays down it goes away for a while. When she sits up, it is painful. She reported she has never experienced pain like this. This was worse than her fall. Her doctor thought things were exasperated by the vaccine and she was given prednisone. She also took Tylenol#3 every 8 or 9 hours. She was wondering since she is scheduled on 07Apr2021 for the 2nd vaccine if she should take the shot and how to know if she should or not do this to do more pain to herself. She stated that the pain was enough to make her cry and she has pinching nerves too underneath her arm and underneath her underarms the pain goes down if it gets really bad. She stated she saw her primary care HCP after she got the COVID Vaccine and she wanted to go to the emergency room but she figured they would give her some type of medication so she went to see the HCP and waited two days to see the doctor. On a Saturday, 27Mar2021, she started getting bad and then Sunday, 28Mar2021, she was awful and then on Monday 29Mar2021, she thought she was dying and saw the doctor on Tuesday, 30Mar2021. She also stated she is out of breath when she is talking on an unspecified date. The outcome of the event "vaccine in the right arm, which swelled up for a while" was recovered on an unspecified date, and unknown for other events.
