traveling tingling, stiffness, and tightness in muscle; traveling tingling, stiffness, and tightness in muscle; traveling tingling, stiffness, and tightness in muscle; stiffness in neck; soreness in her arm at the injection site and shoulder region; muscle aches; This is a spontaneous report from a contactable consumer or other non hcp. A 58-years-old female patient received bnt162b2 (BNT162B2), dose 1 via an unspecified route of administration, administered in Arm Right on 11Feb2021 (Batch/Lot Number: EL9269) as 1ST DOSE, SINGLE for covid-19 immunisation. Medical history included asthma from an unknown date and unknown if ongoing and hypersensitivity from an unknown date and unknown if ongoing . There were no concomitant medications. She does have a tendency to have (for no particular reason), a weakened immune system. She gets sick easy. She is a substitute teacher and she knows when she was going to be teaching little kids, she was going to be sick, but that just was her. She knows its just because she has allergies. She was not sickly but she knows her limits. The patient did not have any prior vaccinations within 4 weeks. The caller 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 didn't 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 doesn't know what muscle that is. It's the muscle that goes up and makes you have a stiff neck if you sleep wrong. The caller states the 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 states 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. The caller explained 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 the caller declined because she knows Benadryl makes her extremely sleepy. Caller confirmed she doesnot have any UPC, Lot number or expiry date for Benadryl, she didnot take any. She has asthma and allergies so she did have an EpiPen and inhaler in case needed for an emergency. She didnot use anything and she didn't take the Benadryl. Caller states she did contact 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 wouldn't have noticed the stiffness if it was in both sides. She could tell one leg (right leg) felt funny and the other didnot. 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 needs to be and its good information to have. The patient did not visited to emergency room/ physician office. Therapeutic measures were taken as a result of events with Tylenol Extra strength both times. The outcome of the events were unknown.  No follow-up attempts are possible. No further information is expected.; Sender's Comments: Linked Report(s) : US-PFIZER INC-2021268268 same patient/drug, different dose/event
