Additional information: Caller is consumer who received the Pfizer booster dose on 12Nov2021 around 1 in the afternoon then 12 hours she got chills and then about 6 Oclock in the morning she got bad headache then felt like she wanted to vomit. Still this lightheadedness is still being experienced up to now. She wants to know if this is something she is going to have for the rest of her life or is it temporary. The chills ended about the time when she had started dry heaving, around 6:00 AM. She would say that the chills lasted maybe 6 hours altogether. The dry heaving probably lasted about 10 to 15 minutes. She was told not to take aspirin if she happened to get a headache so she tried taking Tylenol and it did no good so she went with Excedrin and some headache powders, good's,and that's what finally helped. It was at about 3:00 that afternoon when she was feeling better with the headache. She confirmed that she recovered completely on 13Nov2021. That's when all that basically stopped but the light headedness came about on Monday, she didn't notice it on Saturday or Sunday. She says that Tylenol never works on her headaches, but the lady who gave her the shot said to try that for the headache if she were to get one. She is a production worker. she has an appointment this upcoming Friday to see the doctor regarding the light-headedness because she still feels like crap. She then added, she feels like she got something old in regard to the booster vaccine. Indication: Has a 90-year-old mom at home and a brother at home with heart issues. She works with a bunch of people not vaccinated. She wanted to do her part in getting vaccinated so does not bring any-thing home. Additional Vaccines Administered on Same Date of the Pfizer Suspect: None. Emergency Room: No. Physician Office: Has not gone yet. Has an appointment scheduled for Friday. Relevant Tests: None. At end of call, caller commented she hopes the light headedness will go away. Its dragging her down, making her feel down. She feels like she will have this the rest of her life. History/ Investigations: No, she doesn't believe there is anything else causing this light headedness other than the vaccine because as far as her heart goes, her doctor told her a few months ago that she had a heart like a 20-year-old.  No follow-up attempts possible. No further information expected.
