She received the bivalent formulation (cap color is not on her card) She wants to know are her symptoms going to go away? She has had 5 doses of the covid 19 vaccine. Her symptoms are dizziness and unbalanced issues. This was a booster dose because she have had 5 doses. She had the dizziness coming on for a while and it got worse with the last two that she got. She have to been to every doctor known to man. She have been to two neurosurgeons, to her neurologist, her heart doctor, her breathing doctor, 3 ENT's and no one can find anything wrong with her. They just keep asking her if she have had Covid. She have not had Covid. What are you going to do about it? Pfizer is bound to know this is happening to people. You are just not wanting to admit it. I want to talk to a doctor there. Consumer says she has had five Pfizer COVID 19 vaccine shots and she has had symptoms of being dizzy, disoriented, unbalance issue, and rapid heartbeat.  She went to specialists and they asked her if she had had COVID, which she has not had, she has had 5 vaccine shots. She read the symptoms online, they are not going away, she has had them now for the last 6 months, they are getting worse and worse and she doesn't know what to do. She was 72-years-old, she has fatigue, rapid heartbeat, is dizzy, and has unbalance issues that are not getting better. She would like to know, since enough people know have it that they must know about this, if this is going to go away? She knew when it came out they didn't know what side effects would be, but she is hoping they will have information now. She just had her last COVID vaccine a few months ago. Her symptoms have something to do with position and movement of her head, it gets worse. She has a handwritten vaccine card, NDC/EXP were not provided for her doses of the vaccine. All her vaccine doses would be given on left side because she was right handed and it makes her arm a little sore, so she thinks they were all given in left arm. After her fourth dose was given 02May2022, it has been since that it got really bad. She has a weird kind of like vertigo, but the world doesn't spin, it has to do with position of her head and gets better when she lays down and doesn't move, when she is immobile. She can be in the car driving and it happens. It seems to happen more in the car for some weird reason, maybe movement. At first when she started getting it, it was occasional, and she didn't think about it. The last six months it has been all the time, and it doesn't go away. After the fifth dose which she just had that one, it was really bad now, and she was not taking any more of the vaccines, she was afraid to take any more. Concomitant Medications; With her very last COVID shot she had a flu shot the same day, and she was already having the dizzy spells. It was the same day as COVID shot, at (Vaccine facility name withheld), but she was not sure which flu shot it was. Investigations; She saw a heart doctor who had her wear a thing on her chest, she has been to two neurosurgeons and two neurologists and has had brain MRI and MRA, and she was getting ready to do an EMG and has done an EEG, and been to the breathing doctor. All of her tests have been negative, nothing comes back positive, and every single doctor asked if she has had COVID, but she didn't have COVID. She has had dizzy spells for over a year. When she first had it, they would last 30 seconds then be gone. She was very physical and rides horses, and over the last six months she was thinking she was get Alzheimer's, she has problems thinking, brain fog when she was playing piano and stuff. It seems to be positional, with her head and neck and arms.  She thought it had to do with her back so she went to the two neurologists and two neurosurgeons. They said her symptoms are similar to COVID if that was what was being reported, but she didn't have COVID, and did not have reactions to COVID shot other than a sore arm. She had four shots, and it is horrible now, the dizzy spells don't go away. The doctors couldn't find anything wrong with her. She has dizzy spells, unbalance issues, if she moves her head too fast from one side to the other or up and down, it is like a carnival ride or something.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202201318946 Same patient/vaccine, different dose;
