But last night she was just finishing dinner and all of a sudden she got very dizzy and she end up falling because she couldn't make it to the bed on time. No one seems concerned about this dizziness, She was afraid to drive. She was on a biologic for rheumatoid arthritis so she went at the two week mark, she got it once a month, one vaccine last month, she wanted to get the flu and the RSV. She had 6 vaccines since 2021, (Feb2021, Mar2021 and that was the first two, Dec2021, May2022, Nov2022). This is almost a year later from the last vaccine, seems like it might have been too much of a good thing and that's what's causing the dizziness. She also have various allergies. The first vaccine she was sick for a day or two, but she took a lot of water, but it was all smooth sailing. She thought she was dying it scared her, went to the cardiologist, they monitored her for a week but she also picked up some extra heart beats. She got another two shots of the biologic, but she was nervous that day that it would cause a problem. She had couple of concerns but she got her last the new launched vaccine, Comirnaty on 06Oct2023 and end up in the ER (Emergency Room) for four hours, she had electrolytes messed up, they said she was dehydrated, all she did is drink water. They gave her Magnesium and some sodium and then an IV (Intravenous). She came home and she was okay but she had reoccurring about once to twice a week of dizziness that came out from nowhere. She was immune compromised because she get biologic for her rheumatoid arthritis. Her head just snapped and the room rolled around but she had ongoing about and it just, and she was scared to drive at this point. She have had regular medicine, she take every day. Simvastatin but she do not know how much, she take 2 other pills. In the morning she took, Valsartan/HCTZ and the other one is Levoxyl before her vaccine, she took both of those in the morning before she had the vaccine.
