Additional Information: Reason for no lot number: of Pfizer COVID vaccine: Complainant does not have the product with them at the time of call. Received call from consumer regarding the Pfizer COVID Vaccine Booster. She is calling on behalf of her husband, who is at the doctor's office. She tried to report on CDC. She talked to Pfizer before about another drug and Pfizer was very informative and upfront. She does not have a reference number for previous report. They both got all of their booster doses at the same time 12 days ago. Her husband's issue occurred the very next day. She provided his weight as being between 185-190 lbs. She did not have an email for provider. His primary care is retired and he is seeing her primary care to see if there is anything they can do to relieve the pain that is not a heavy medication. He did see his orthopedic guy. He went to see him before and that is the name and contact details she provided. He had spinal surgery and had neck and vertebrae fused Nov2019. That was the doctor that recommended the doctor who did the surgery. She later stated it was Oct2019 instead of Nov2019. The day after the booster shot, he began to have pain in left side, which he never had on that side before. It was in his neck and went down to his scapula. Then, his armpit was tender and very lumpy down his rib cage, so she looked it up and there had been reports of lymphadenopathy. 31Dec2021 is the day he received booster shot. They had to drive quite a distance to come back to (Name withheld) and knew he struggled the entire way. The first stated it was persisting. She would say it is a tiny bit better, he can find places where he sits or moves where he can stop it, but it is a stabbing pain. It is hard to describe. It is a muscle that tightens in his neck and she can feel it and it goes down the scapula. Then he has a feeling of congestion in the front. He is swollen on left side below clavicle. She did not feel armpit because he got worse after driving. She tried to probe around to try and help relieve him. That was by 03Jan2022. Lumpy rib cage improved quite a bit. She used it as a massage center for him and could not get into a doctor right away. It seemed as though massaging tending to help them release. On 04Jan2022, he said that was bothering him. That was the least of the things. The stabbing pain is in his shoulder and connection where trapezius comes across that spot in his shoulder. It is not painful, just kind of a presence. He received Pfizer COVID vaccine booster on 31Dec2021. Lot and expiration are unknown. It was injected in his left arm. 1st dose of Pfizer COVID vaccine given on 05Feb2021, Lot and expiration are unknown. It was injected in his left arm. The 2nd dose of the Pfizer COVID vaccine was 26Feb2021, Lot and expiration are unknown. Injected in Left arm. They decided to get the booster because there was so much to talk about. He is a younger man. The is 81. They thought maybe they were more at risk than they think they are and his sister had gotten it and thought they were being foolish to wait. He takes no medications. The only thing is that he had spinal surgery. They received it while in (Name withheld). If they came back to (state name), there would have been a month wait. When they called to get it in (Name withheld), they had it the next day. They both had sore arms with the first two. It was no biggie and it was in the left arm. She said it kind of matters that they did everything together and she had no significant things. She did have a strange event. Separate report completed for her. He also felt a little funny on Saturday, after getting his booster. The pain portion started on the 02Jan2022. His sore arm lasted a day or so, and was very minor. Physician Office visit : Yes The Orthopedic doctor. He x-rayed him to determine if related to surgery and it was not. He said he could not offer anything other than take Tylenol unless he wanted a heavier medication, which he did not. No Prior Vaccinations (within 4 weeks).

She does not know enough to complete report for him other than he is dealing with the same thing. Separate report completed for his doctor. She just felt Pfizer should know there are people that are experiencing these side effects. It is not mentioned and it may have changed their mind about it. She thinks people should know there is a chance of having a reaction and her husband has really suffered.  No follow-up attempts are possible; information about lot/batch number cannot be obtained.
