stiffness and muscle ache that came and went; stiffness and muscle ache that came and went/ muscle stiffness in neck; chilled, could not get warm; soreness in her arm at the injection site and shoulder region; fatigued; traveling tingling, stiffness, and tightness in muscle; This is spontaneous report from a contactable consumer. This a 58-year-old female consumer (patient) reported for herself that she received her second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; Solution for injection, Batch/Lot number: EN6198) intramuscularly into the left arm (in shoulder area) on 04Mar2021 (at the age of 58-year-old) as single dose for COVID-19 immunisation. The patient medical history included asthma, allergies. She does have a tendency to have (for no particular reason), a weakened immune system. She gets sick easy. Concomitant medications were not reported. The patient received her first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; Solution for injection, Batch/Lot number: EL9269) intramuscularly into the right arm on 11Feb2021 around 11:45-11:50AM (at the age of 58-year-old) as single dose for COVID-19 immunisation which resulted in traveling tingling, stiffness, stiffness in neck, soreness in her arm at the injection site and shoulder region and tightness in muscle.  On an unspecified date, the patient reported of stiffness and muscle ache that came and went, muscle stiffness in neck, chilled, could not get warm, soreness in the same shoulder the vaccine was given in and fatigued. She had no tingling in her arm with the second dose. She had normal stiffness and muscle ache that came and went. She clarifies the second dose was given in her left arm because she still had muscle stiffness in her neck. Her neck was still tender. She has had this muscle stiffness the whole month. With the second dose, she still had the normal stiffness and soreness in the same shoulder the vaccine was given in. With the second dose, the caller confirms she did get muscle stiffness and soreness in her left arm that goes up into her neck, but she did not have the tingliness. She had the same symptoms again in the arm she received the vaccine in except she didn't have tingliness, just the stiffness. It was definitely a lighter reaction that it was initially. For the next 3 or 4 days, she would wake up feeling okay, and end up by the evening, feeling just like she just went out and walked 10 miles- her muscle were stiff, fatigued, and ached. She also was cold and what she describes as being chilled. She did not have the chills, but she could not get warm. This lasted 3 days after the shot but that stopped. She has been checking her temperature. Time the vaccination was given was right around noon, because she knows she waited afterwards until 12:30 or 12:33 or 12:34. She had muscle pains and her neck was still bothering her. She definitely still had stiffness in her neck and muscle going from shoulder to neck. No prior vaccinations (within 4 weeks). Treatment included Tylenol Extra strength both times. She does occasionally take Advil sinus for her sinus conditions. However, she was told to not take Advil within 2 weeks of the vaccine so she didn't have any. She may have taken Loratadine or something like that, something minor. Maybe a Tylenol Sinus for allergy related stuff. The patient did not care to go and do the V-Safe and have it tracked. She knew someone that did but she was not sure if it was one with Pfizer or what but she did not want to be annoyed with it and was told it asks questions every day and all sorts of stuff. She had allergies and she knew she could get a reaction, so it was not alarming and not a big deal when she got one. She was 57 or 58, she believes she was 58 and commented that her brain was not working. Once you get past 50, you do not count and feel old. She explains after the first dose, she ended up staying at the vaccine facility for about 45 minutes. Within 10 minutes of receiving the vaccine, the arm that the shot was given in, started to feel tingly and stiffness. This kind of stiffness went to her fingers. Her arm did not go completely stiff. It was traveling, tingling and stiffness and tightness in her muscle. This did go up into the muscle that goes up into neck, she does not know what muscle that is. It was the muscle that goes up and makes you have a stiff neck if you sleep wrong. Stiffness in her neck was on the same side, clarified later as the right side. This was within the first 10 minutes after the shot and lasted about 20-25 minutes or however long it was past the half hour she had to wait. She stated she know once she reached the half hour point, it was still getting a little bit worse but not much. She waited another 15 minute and by then it had gotten a little better, so she left. She explains with the initial dose and after having the reaction, a nurse came and asked her a bunch of questions and checked her temperature. The nurse kept offering her Benadryl but she declined because she knows Benadryl makes her extremely sleepy. She has asthma and allergies, so she did have an EpiPen and inhaler in case needed for an emergency. She did not use anything and did not take the Benadryl. Contacted her allergist and the allergist said it made sense to them and to continue to monitor what was going on. The stiffness and muscle aches in that arm continued in the same side that whole day and went down into her leg, but it was not bad on her leg. Her leg felt stiff but she would not have noticed the stiffness if it was in both sides. She could tell one leg (right leg) felt funny and the other did not. The tingliness went away within an hour or two. She had what she calls normal vaccination soreness in her arm at the injection site and shoulder region. She did take tylenol, she was advised not to take Advil or anything else. She had no problems the next day. The muscle soreness came back the second night after receiving the first vaccine. She was not at all concerned, she was only reporting this today because she knows little was known and she figured it needed to be and it was good information to have. She does have a history of having shoulder surgery. She has had frozen shoulders in both shoulders within the last 5 years. She has massage therapist and the massage therapist theory is that it goes to where your body is normally weak. No investigation assessment. Outcome for the event stiffness and muscle ache that came and went was resolved and for event muscle stiffness in neck was not resolved, and all other events were unknown.   No follow-up attempts are possible. No further information is expected.; Sender's Comments: Linked Report(s) : US-PFIZER INC-2021268198 same patient/drug, different dose/event
