She had a mild outbreak of shingles which began about three days (on 14Oct2023 or 15Oct2023) after she got the vaccine. She did not know it was shingles at first and just had an itch on the left breast and it went a little bit under her arm for a little patch but not in the area where she puts deodorant or shaves and it was more towards the back and that afternoon  she kept itching and scratched through the shirt and when she took of her shirt off that night, she looked in the mirror and she saw little dots and thought it was some kind of bite like an insect of some sort. She looked closer and it was red underneath and had these little dots of patches on her breast and a patch under her arm and kept looking at it every day morning and night. She wears contact lenses and uses reading glasses and looked in a magnifying glass with light and finally noticed the blisters after a couple days on those same spots and she thought they were bites, and she was a medical nurse in a hospital so she has seen so many cases of shingles and has had family members with shingles, so she knows what shingles are. Now they are fading away and she can still see traces of it and it is not getting any worse than the spots she told this agent about and she counted 6 on her breast and four under the arm and they did not rupture. The blisters she could see underneath her bra on the breast and knows it was not an insect and she took her shirt off and saw spots and looked inside the shirt but saw spots and was itching and put Cerave cream on it and when she saw the blisters and thought about looking shingles up online again to refresh her memory and read that prednisone could help it so she bought some cortisone which turned out to be ointment but she intended to get cream so she used that. The blisters she looked at every time she was in the shower, and they were still there and thinks the ointment was not such a good idea so she stopped using it. She did not go to the doctor and thought it was stupid to pay him to tell her what she already knows. Causality: She would think "not the shingles is not directly related" and thinks it probably riled her immune system and reactivated her roster virus; however, if she had not gotten this covid vaccine she would not have had an outbreak.
