Additional information: The patient did not receive additional vaccines administered on same date of the Pfizer suspect. Clinical course: Patient received her 1st Pfizer COVID-19 vaccine on 27Mar2021, and she was experiencing a pain under the arm/armpit incredibly sore where she received the vaccine; weird intermittent, low grade, background kind of like nausea. She also reported she was a little more tired the rest of the weekend. But, she woke this morning and her armpit hurts, it's a really weird place to hurt. So she went looking through the literature she was provided when she got the vaccine and it listd swollen lymph nodes. If she was remembering anatomy correctly, she thought that was where a lymph node might be, but she thought maybe she should call. She confirmed she saw swollen lymph nodes was listed on the lovely documentation she got, and every thing she has experienced is listed on the documentation, but she did not know if the random sore armpit qualified as a swollen lymph node and if that was where lymph nodes were. Stated it was just kind of weird. As a woman, it was kind of like having an ill fitting bra and the underwire was kind of poking in the wrong spot, it was  that kind of thing. It was not debilitating, just kind of hurts, kind of weird. Stated she really started feeling tired in the evening on Saturday, 27Mar2021. Stated she hit a wall in the evening Saturday, 27Mar2021. The worst was the night of 27Mar2021. She was a little sluggish yesterday and overslept a bit this morning but a lot of that could also be contributed to the fact that she had 2 small children, so tired was a common thing with her. She just really kind of hit a wall, it was really all of a sudden, like "woah" the evening of the 27 Mar 2021. The tiredness had then since returned to the "normal level of mom in a pandemic tired. Stated the mild nausea started 28Mar2021 in the afternoon. She actually ate something and still kind of felt the background tiny bit of queasiness. The events did not result to emergency room or physician office visit.    No follow-up attempts are possible. No further information is expected.
