it takes her a while to get the body parts moving; She does not feel like eating; headache; her stomach is pretty upset; her neck is kind of stiff/Aches were Neck/back of head is kind of stiff; pain around the arm/her arm was hurt/upper left arm to bottom of arm was sore; This is a spontaneous report from a contactable consumer (patient) reported that: A 74-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE; Solution for injection), dose 1 via an unspecified route of administration, administered in Arm Left on Friday, 12Mar2021 in the early morning probably about 08:30 AM as single dose for covid-19 immunisation. She was 5'4, but thinks she shrunk a little bit and is now 5 feet 3 inch. Initially stated no medical history, but then reported she gets migraines. Caller reported she does not get them on a regular basis; had more in her younger years, migraines are hormone driven and once she went through menopause, she stopped having them regular; she maybe gets them 5 or 6 times a year now. The patient's concomitant medications were not reported. No additional vaccines administered on same date of the Pfizer Suspect. The patient really did not have a reaction on the day of the vaccine, no swelling or soreness. The next day, Saturday, 13Mar2021, and Sunday, 14Mar2021, she noticed her arm was hurt, she wants to know if that could be a reaction. The patient stated that, at the time, she just dismissed it. It stopped hurting on Sunday. Today, 16Mar2021, on Day 4, she woke up with a headache and her stomach is pretty upset. She heard people say right after they got the shot that they had side effects, the same thing she is having, so she doesn't know if this is random and doesn't know if it's connected to the vaccine or not. She is concerned and wants to know if she should get the next dose of the vaccine. Clarified the pain was not at the injection site; her upper arm and maybe to her elbow was just sore, no swelling or redness, just sore arm. This lasted through the next couple of days after the shot. Patient mentioned that she absolutely did not have much of a reaction; she has had issues with bee stings in the past, described as big, huge swelling and redness, no breathing associated with it. Patient stated she has been told that is a reaction. She clarified she did not have anything like that on the day of the injection itself. She is in between doctors right now; she doesn't have PCP. She hears from friends that the PCPs do a lot of diagnosing and treatment over the phone. She doesn't know if it's a state thing because she's been to dermatologist, eye doctor, had her teeth cleaned twice at the dentist during this pandemic. It feels like maybe she has some aches; her neck is kind of stiff, maybe because she has been in bed all day, because of her age, she can feel aches and pains more often. Patient also mentioned that in the morning, it takes her a while to get the body parts moving. She has not been up and has been in bed. She is laying back down again because her neck or back of her head felt kind of stiff. No treatment was taken. She did not take or eat anything today yet because her stomach has been upset. It has been 4 days since she received the vaccine, and she would assume she would've gotten the side effects closer to the day of injection. She is scheduled for the second dose on 29Mar2021, and she has questions about that: if this means anything, is this connected to the injection. Headache started at about 6 AM when she woke up this morning. She has been holding off on taking Aleve or Excedrin because of the upset stomach waiting for that to calm down because she does not want to throw up. She does not feel like eating. She has not eaten yet, but she knows she needs to. She doesn't know if it's her neck or the back of her head, but it is kind of painful when she stands up. Her stomach might feel a little better, not that she's hungry, but she's thinking more that she needs to eat whereas this morning she was not going to do it and didn't care. She has basically been in bed all day; she spent more than an hour on hold. Clarified that she was not sleeping, but in bed. When she got up, she noticed pain in her neck or back of head. She had not been up long enough to tell if it's still going on, she just got up once or twice for a quick bathroom break.
