Additional information: Received call from consumer regarding the Pfizer COVID vaccine. She is 70 and got it when it came out last year. She first stated she got the booster on Nov2021, but later clarified it as 08Dec2021. She thinks she was 69 with the first shot. It started after the first shot, but she did not take it seriously. She provided another ethnicity as: (withheld). Grandparents came from (withheld). In (withheld)they say (withheld). She lives here for 41 years and got the shots here. She was just living in hope and has not reported it. She first stated her left hand was swollen. She clarified later as left arm. She used hand and arm interchangeably and kept getting confused about hand versus arm but clarified throughout that it was her arm for all. She went to pharmacy and reported to them, and then to her doctor and they said it would go away. She waited and waited. She was stupid enough to take second one. She got the same side effect. She still hopes it will go away and has been a year. In Nov2021, she got the booster and that was the killer. She received two in the right hand and one in the left hand and later stated it was given in the muscles of her arm. She then clarified after providing the lot numbers that two were in the left arm and one was in the right arm. She cannot remember exact start date because she did not document it. Her arm is getting heavy and numb, so she went to the emergency room, and they did some test and sent to her doctor. Her doctor referred to a neurologist and he did the test, and it was a painful test. She did the test, and they find out that she has nerve damage in both arms because she can hardly use them, and it is heavy and it scares her. She wants to know if it was a stroke and that worries her the most. When she finished the test and now her doctor will send her to do an MRI. She cannot use the hand or arm. The muscles where she got it on both arms is getting numb and heavy. She feels she cannot express it. She feels weak. She needed to get her other glasses to read the vaccine card. She confirmed that she needed those prior to getting the vaccine. The glasses she got are the ones she wears all the time. They are not new, and she needed them before for a year or so before getting the vaccine. After the 1st vaccine it was swollen on right arm. She confirmed that all 3 were the Pfizer COVID vaccines. 2nd dose given on 04Mar2021. Lot EL9264 expiration is unknown. Injected into left arm. 3rd booster dose given on 08Dec2021 injected in left arm. Lot FJ8762, expiration is unknown. When she started having pain is when she went to pharmacy. She just takes regular medications and did not take anything for pain or anything. Unknown name of test that she had done at the neurologist. It was painful. Her doctor has results, but she does not know name or results other than the nerve damage. After getting the 1st shot at (pharmacy name withheld), she got Pneumonia shot on May2021. She always gets the single shot that is every 5 years, and she never had the problem. She never had problems getting flu shot, pneumonia shot, or shingles shot. She does not have a manufacturer, lot or expiration and does not remember the exact date. She did not take it serious at first because it takes too long for her to report it and she didn't think it would last.  No follow-up attempts are needed. No further information is expected.
