She stated that her doctors were against her staying with her daughter and mentioned that she thought that it should be fine for her since the vaccine should be able to protect her. She clarified what she meant by her having a reaction to this last one, she experienced difficulty breathing, at first, she was not sure why, so then she read the paperwork to see, she was able to check off difficulty breathing, dizzy, and weak. It did not last long, it lasted just day or 2. She also experienced chest pain, it was like an elephant sitting on her chest. She was tired, had muscle pain, chills, she was nauseous but didn't throw up. She did not have arm pain where the injection site was but felt pain on the opposite arm and it was not red, that's the way it usually was. She again stated that she is not sure if this is all related. she stated that she doesn't know when it started, she recalled thinking oh gosh she doesn't feel well, maybe it's a reaction, she read it as it was something that came across, something effecting her. She got the shot in the doctors office, when she came home she didn't feel bad, the next day she even took her bandage off on 30Jun2022, and asked her daughter if she saw anything because her daughters usually gets red, hard, and hot but her daughter told her she saw nothing on her arm. She stated that then it was the first of July when she felt the heaviness in the chest and everything she said prior. No investigation, she was at the doctors office because she had a blood test, she didn't receive any shots at the visit except this. She did not think she needed it, but she could tell by her doctors eyes that she wanted to her to get it. she clarified that the Blood work was on Monday 27Jun2022 and appointment was on Wednesday 29Jun2022, the blood work was cholesterol and other stuff they check regularly, there was some stuff that went up and down.
