On the evening about 8 hours after the Covid 19 injection she got a rash on her shoulder that she had the shot in. The rash went across her chest to the other shoulder. On her neck she had hives up to her face and down her chest a little bit. She has been taking Benadryl for the past 6 days. She is very concerned what is going to happen with the next dose. She contacted her primary health care provider and it was recommended that the caller pre-medicate. The caller states it says not to pre-medicate. She has her next Covid 19 vaccine in 2 weeks and she was nervous. She did file a report with the government. It was in the information she received from the hospital where she got her Covid 19 injection. Every day at 2:00PM she gets a text message. They monitor her for up to a year. Every day she checks in and says how she feels, is she having trouble completing daily activities, did you have to call your doctor. They gave her a paper at the hospital where she had it done.

She is due for the second Covid vaccine on 26Mar2021. It was reported that several hours after the injection in the evening, maybe 8 hours after she had the injection is when her symptoms began. She does feel like she is improving. Today was the first morning that she didn't take the Benadryl. She had no respiratory problems. But she was very concerned because the hives were pretty prevalent. It was very uncomfortable. She was taking 50mg of Benadryl for 5 days. When she went to the pharmacy to pick up a cream too, the pharmacist thought that a steroid would be good. She was concerned. She emailed her primary care doctor with pictures. When querying seriousness of events, caller states it was bad enough that she went to the pharmacy and called her primary care doctor and sent her pictures. If she had developed any respiratory issues she would have gone to the emergency room. If she was non medical she would have gone to the emergency room but because she's a nurse she thought she would ride it out.

When querying red and itchy eyes, she reports only the eyelid. When querying gastrointestinal issues, she reports she has diarrhea, but she has gastrointestinal issues.
