A 51-years-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection), dose 1 via an unspecified route of administration, administered in Arm Left on 27Jan2021 15:00 as single dose for covid-19 immunization.Medical history included menopause or has been through menopause, Flu shot, hormonal issues, she started with a bizarre virus, whole lymph node response; It was lymph nodes in her neck, arm pits, and groin. Every two days she would have lymph nodes reacting, she had a little infection and inflammatory markers come back positive. Concomitant medication included probiotics, vitamin c [ascorbic acid] (VITAMIN C [ASCORBIC ACID]) and vitamin d [vitamin d nos] (VITAMIN D [VITAMIN D NOS]). The patient previously took flu for influenza immunisation and experienced peripheral swelling, tetanus vaccine for immunisation, amoxicillin, and experienced drug hypersensitivity, flagyl [metronidazole] and experienced drug hypersensitivity. The patient reported adverse events associated with her first Pfizer COVID vaccine shot. She experienced swelling in the upper breast area, swelling and pain in the neck, swelling in the armpits (for about 7 days) that got very itchy for 3-4 days but has since disappeared. She thought on whether to get the second shot of the vaccine considering these side effects since her doctor did not know why this was happening according to her. She thought she would report some side effects after one shot of the Pfizer COVID19 Vaccine. It was strange. She did not read the symptoms until seven days out. Then she saw some have reported a lot less. After the shot, that night she had swelling in her upper chest. She thought it was lymph nodes in the breast and chest area on the side she got the shot. The next day her arm that she got the vaccine in got very large. Then, she does not know if it was related, two days later she had itching on both of her feet. It was the tops of her feet and only for a couple of days. She is not counting that. Day five after the shot has been the main problem. Her armpits started itching like crazy. It was severe itching and swelling in her armpits. The itching lasted for three to four days. The lymph nodes in her arm are still swollen. It was five days after the shot. It was both armpits. The night of the shot she had a lot of neck pain and she thought it was probably the lymph nodes in the back of her neck. That has lasted and was slowly diminishing. The patient was not planning on getting it. There was an agency that for assisted living for people that need help. They were giving it and had extra doses. This guy in charge at the assisted living house offered it to caller and caller's husband because her and her husband run a behavior health counseling. He offered it to them as healthcare professionals. He was given a batch for the residential agency but had extras. She was going through menopause or has been through menopause. She has hot flashes and has hormonal issues. The first week of December she started with a bizarre virus. She got tested for COVID and it was negative. It was not a rapid test it was a sendoff. Through that illness she had a whole lymph node response which was super unusual. The doctor said it was really strange. It was lymph nodes in her neck, arm pits, and groin. Every two days she would have lymph nodes reacting. She had recovered from that and was back to normal. Four days before she got the shot all of that had resolved. Prior to getting the vaccine she had been tested for Lymphoma and it was negative, and she had a little infection, and her white blood count was normal. She had inflammatory markers come back positive prior to getting the vaccine. She went to the doctor on 27Jan2021 and asked if she should get the shot. The doctor said to do it because if she got COVID it would be worse. She was going to have a follow up with doctor for the ongoing stuff and he might do more test. Never in the course of any of that did she have itching armpits or swelling that lasted all this time. She never had chest swelling. The shot in the arm and it moved across her chest. It was reported that, back in the 90's, in 1993 or 1994, flu shots caused her arm to swell really large and stayed swollen for three months. That was the last three flu shots she got in the 90's. Then the doctor said not to get them. No one said why. She doesn't have allergy to eggs or anything that she knows to cause that. She has gotten all other vaccines and tetanus within the last 10 years. Her arm would kind of react but not like that. It went away in a reasonable amount of time. She didn't get a fever.
