Patient was very good at record keeping, patient had advised all patients to save everything because she had worked in the medical field for years. They stuck the needle and sucked the blood out, the wording gynecologist use was your breast has to be cleaned out, they need to go in and biopsy and clean it out. Caller said that she had her 1st dose in Mar2021 at the (withheld) and then she had the 2nd dose in Apr2021 and within 2 1/2 weeks she had her side effects. The COVID vaccine was given in her left arm. Her left breast was all swollen and she called the gynecologist. She did not felt cancer or anything, but she felt something, and the gynecologist said to come in right away and the caller had a left breast mammogram and an ultrasound. On the mammogram the doctor noted that the lymph node was enlarged and on the note it was said that it is probably due to the COVID vaccine. But just in Dec2020 she had a negative mammogram and an ultrasound of the breast. There was a tiny cyst, not even 2 CM at 12:00, and then all of a sudden now it is enlarged, and it blew up. Following that she needed to have a needle aspiration done on the same day of the cyst and that was okay. The swelling of her breast caused the duct to swell and clog but that got better a little bit and it had gone down. They were not talking about being into May2021 and they found a papilloma that was not there in Dec2020 prior to this inflammation. On 21Jun2021 she had to have breast surgery and they were still waiting for the results of that, but they removed the papilloma. It was a tiny little thing, and they did not think that it was cancer. Everything was inflamed due to the COVID vaccine. It has just been one thing after another. The cyst blew up which caused the breast to swell and then it went down after she saw a radiologist in (withheld). The needle had to go through the duct to unclog it and they took all of it out, it was only blood, but it was swollen and inflamed. They had thought that maybe it was an infection, but it wasn't it was just swollen. She has 30 pages of reports from this before the COVID vaccine with her prior mammogram and all of this. Does this reaction she had mean that she will get inflammation on her right breast. She had to get the COVID vaccine because she worked in a physical therapy office at the front desk and her parents are 89 years old. She was calling because she wanted to tell what happened and she wants to know if there was compensation. Her breast was so swollen, and it did went down but now she had to heal from that and the thing is they did not think that it was cancer but whatever was there was inflamed and she was unable to explain it but the COVID vaccine aggravated the breast from the duct that was clogged, the cyst that was enlarged, the breast being swollen and warm and under her arm was swollen. She thought that it might go away on its own, but all of her doctors flipped out and said that she needed to go through all the tests and have all of the follow up because they don't want her to get breast cancer. The duct was clogged first and then they found the cyst that was inflamed. In Dec2020 she had negative reports and she had no symptoms. It was from the 2nd dose of the COVID vaccine. Hospital had her records. They are aware of all of this; the gynecologist is and the radiologist company in (withheld). They were all shaking their heads and they don't want all women to go through this and there is a lot of emotional anguish with this because it is a big scare. She was getting anguish from this. She felt like this is due to the COVID vaccine because all of this was brought on when she had that. She was in perfect health. She had no blood pressure problems, she was on no medication, she doesn't smoke and again, she is on no other medication except for a multivitamin and supplements, she is not even on an aspirin.
