Her daughter told her it was because she was dehydrated. Her daughter told her that it was called vagus something or another. Her daughter was not there with the caller. Her daughter called it vagus something, she does not remember. Her daughter told her that it had to do with inflammation and her immune system. Caller stated she also has arthritis. Her daughter told her that she was stupid for drinking wine after receiving the second dose of the covid vaccine and not eating a full meal. Whenever she passed out and fell, she did not hurt herself but it was a wake up call. She realized she was vulnerable. She was calling because she did not know why no one told her to drink a lot of water after receiving the vaccine. She got a Prolia shot in July and the nurses told her to drink a lot of water. She was asking why the nurses who gave her the covid vaccine are not saying that to people. Her daughter told her to call the doctors office about this, and she told her daughter that it was over with now, she's 95%, she was a little tired on 18Mar2021. She was unconscious for 15 seconds per her husband. Her husband was shouting her name, and she did not hear anything. She wanted to call and report that the nurses should tell people to drink water.

About 10 hours after receiving the second dose of the covid vaccine her hand on the side that she got the vaccine was cold. She got the vaccine about 10AM, and about 10PM at night is whenever her hand got cold. She had pain at the injection site where she had the first dose of the vaccine too. She had more pain at injection site after the second dose of the vaccine. It was not awful, but only if she pressed on it. Clarified that she gets Prolia shots twice a year for her arthritis. Luckily whenever she started to get dizzy, she braced her self, whenever she fell, she did not fall from an upright position. She was crouched over, and fell against trays that fell with her. Her doctor daughter told her that inflammation was because of her immune system. One other thing was that she has been stung in the past and had extreme reactions from yellow jackets in the 90's. She thought her immune system was sensitive. One other things related to her autoimmune from 3 years ago. She moved to a city in 2012. Everyone told her after 5 years she would develop allergies. In 2017, she had eczema all over her back and arms. It was not just like a topical thing where she scratched and itched, it was under her skin. She went to a dermatologist and he took a biopsy, but the results just said eczema. She went to an allergist, he finally found a space on her underarms where he could do a test. The test showed that she had mild allergies to mold and juniper. Juniper is a tree that they have there, she has one in her back yard. Her allergy was very mild. She tried everything, and in 4 months it went away. Now she just latherers her skin with coconut oil. Her diagnosis that this autoimmune issue was related her immune response from the yellow jacket reaction is a self diagnosis. A doctor had never told her this, this was coming from her own self.
