By the next day she felt well enough to shower, and she saw that she had 2 inches by 3 inches raised red whelp. In Dec2021 she had a mastectomy on right side. The two nodes that were removed on right were also red and raised. She was told to get the shot, she went to the oncologist and got antibiotics because she didn't want to be in the ER for an infection. She took the antibiotics for five days. She asked her doctor, looking at the redness, the redness looked like a bar of soap, 2 inches or 3 inches. Not sure if she missed the muscle and it went in the tissue or if an adverse event. The whole day Wednesday she had a fever and then she took Tylenol and the fever subsided for several hours. She took her temperature again and it was going back up again. But by Thursday no fever or anything, then she saw the red whelp.

When querying seriousness criteria, caller states the weakness, couldn't make it to the toilet to urinate, 2 inches by 3 inches red whelp on right arm at injection site, would be between medically significant and disabling. On her chest, near her right armpit, there were two nodes that were also red and raised. Her doctor was more interested in the arm. The doctor was afraid the pharmacist who administered the injection, missed the muscle and the vaccine went into the arm. Because with the first Covid vaccine her arm was fine. When giving an intramuscular injection it is supposed to be given straight in, maybe the pharmacist went in at an angle and gave a subcutaneous injection. She was so sick with the fever. She saw the two nodes on her chest were red and raised on the 24Feb2022. Redness went away after about three weeks, it took longer. Treatment included she was on doxycycline for the redness and right arm swelling so then she got a urinary tract infection from the antibiotic. Then she went to her primary care doctor. The normal flora in her bladder was disturbed so she needed another antibiotic, Ciprofloxacin, 250mg by mouth every 12 hours for five days, in a pharmacy bottle, ndc/lot/expiration unknown.
