A 74-years-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection), dose 1 via an unspecified route of administration, in left arm on 27Jan2021 (Batch/Lot Number: EL9263) as single dose for covid-19 immunisation. Medical history included patient was diagnosed with glaucoma about a year or a little over a year, prediabetes, cholesterol and blood pressure. Concomitant medication(s) included simvastatin (SIMVASTATIN) 40 mg once daily taken for cholesterol, lisinopril (LISINOPRIL) 20 mg once daily by mouth taken for blood pressure; metformin (METFORMIN) 30 mg once daily taken for diabetes; timolol (TIMOLOL) taken for diabetes, dorzolamide hydrochloride (DORZOLOMIDE HYDROCHLORIDE) taken for glaucoma. After vaccination from that day until now (11Feb2021), patient still has pain on the injection site. She wanted to know if that is usual. She is concerned because she had heard that the AEs from the second dose are worse than from the first dose. Patient family doctor didn't want to entertain her concern. Her doctor said that she should refer to the one who gave the vaccine which is from the County in (State). Patient couldn't believe her doctor wouldn't want to take care of me since he said my AE is related to the vaccine. This was the weirdest thing she had from her doctor.Patient called and stated that she was am a person who received the Pfizer vaccine 16 days ago and she was experiencing still sore muscles in the arm where it was given she could not bend my arm as far as she use to be able to she cannot flex it toward her shoulders and its she just talked to her doctor's office where she told them sahe was having some adverse effects from the shot. Patient was calling to see if got any same reports of peoples whose arms got stiff, muscles are stiff, can't flex, sore, even like she say she was now 16 days after the injection she think that's a little bit long to still be feeling something. Patient also mentioned she was beginning to wonder if she going to get rid of this soreness in her arm or is that something permanent. Patient explained further when she first got it she did experience localized pain, I did not experience fever, did experience though shivering or chills but kind of thought that was because it was chilly but it might have been from the vaccine now that she think about it but she was not sure mostly it was the soreness in my arm that's her main concern is this lingering soreness in the arm after 16 days she had the injection on the 27Jan. At end of call mentioned she had seen the general side effects and may have experienced a few more other than this one but this is the one that's still with her not being able to utilize my left arm like she was used to be able to do even just reaching up to a cabinet for something in a higher cabinet or something she can't do that without feeling she was going to drop what she was reaching for and its sore its sore to do it. Reaching for a skillet down below in a lower cabinet it's like no it's not going to work or getting a gallon of milk out of the refrigerator I almost dropped it. So she feel like what was going on here I should be over this by now she can't, with both arm she use to be able to bend at the elbow and touch my shoulder well she cannot still can with my right arm but with the left arm she can't do that. She like 2 inches from being able to touch my shoulder. Fixing her hair she can't reach back behind my head very easily its with pain and effort to brush and she was left handed so maybe I shouldn't have gotten it in my left arm here I am 16 days later and she still feel like I can't utilize my arm like she use to be able to not totally disabled but know its disability in it and its annoying the pain was annoying even taking Ibuprofen.Patient really didn't have much effects, a little bit of chills but they were having cold weather, she was from (State) so she might get a chill if she opens up the windows. She really had no significant adverse effects at first except soreness in the arm, she says of the things recanted on the internet, she didn't have fever, she may have had some chills but she was lethargic, she didn't feel like doing anything, so she guesses she would say tiredness for the first day or so but what bothers her is that was 27Jan and she still does not have full use of the arm in movement. The arm used to be able to, without hesitation, reach behind her head to brush her hair or reach to fix her necklaces those things she couldn't do and she would say oh goodness what is going on. She has pain if she tries to force it and she thought well she will exercise to limber it up. She is not having continual pain like if she leaves her arm down comfortably but trying to do activity like reaching up to her shoulder or her neck or behind her head. She couldn't do that she would say the last few days it has been a little bit better but there is still pain there. Her vaccine card is in her purse she is going to be going go to the appointment in a couple of days and it scares her because she don't want to have her arm on the other side hurt, if she gets she was going to ask them to put it on the other side but she doesn't want to go through this again and what if it is permanent and both arms are then disabled she would rather have one of them working than both of them. Prior to the injection, her arm had no problem. She states she cannot touch her shoulder anymore and is unable to reach behind her neck to latch a necklace. She states now, she feels discomfort in her forearm and not as much in the upper arm. She states sometimes the pain goes into her hand; she states while she is quietly watching tv, she notices some throbbing going into her hand. She's not affected by arthritis and things like that and she's had pretty good health. She has gotten the flu and pneumonia shot and any other injections with no problem. She had a comfortable initial stick when she received the COVID vaccine with no particular pain at the time of injection. She stated she did not want to do anything for 2 days and was really tired with a stiff and sore arm. She called the doctor after 2 weeks and was not able to get ahold of a doctor. Caller is wondering if there have been reports of duration of this side effect for this long and whether or not she should receive the second shot. The outcome of the events not resolved for injection site pain and myalgia and unknown for rest of the events.
