severe aches; voice very raspy; headache/lingering headache; wiped out /fatigued/tired; lethargic; it took a minute for her to catch her breath; flushed; itchy; muscle aches; something that look like hives on the arm/hives on the lower right arm; skin felt really hot to touch; fire engine red on the right upper arm; pain at the injection site; This is a spontaneous report from a contactable nurse (patient herself). A 46-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot: EK9231), via an unspecified route of administration on 06Jan2021 11:00 in deltoid left at single dose for covid-19 immunization. There were no medical history and concomitant medications.  Family medical history relevant to event was none. Relevant tests were none. Patient reported she received the Pfizer COVID-19 vaccine on 06Jan2021 and had pain at the injection site. On 07Jan21 she started having muscle aches and got something that look like hives on the arm and her skin felt really hot to touch, it was fire engine red on the right upper arm. On 08Jan2021, she woke up and felt like she got hit by a tractor trailer, has severe aches, voice very raspy, and very wiped out with headaches.  Patient mentioned injection site arm was bright red and warm to touch after injection, but has improved. When waking up this morning on 08Jan2021 even walking this morning from the bedroom to the bathroom she was fatigued and it has gotten better with her walking around, but she still felt wiped out. The muscle aches was very short lived. She went to do something at work and it took a minute for her to catch her breath and that and the muscle aches went away and that was it. An hour later she felt very flushed and itchy and coworkers joked with her about what she ate for lunch, which was nothing different. On the opposite arm from injection arm she had hives on the lower right arm. They were there about 15-20 minutes and it turned completely fire engine red and that lasted about half an hour. She showed the doctor she worked with and they recommended diphenhydramine hydrochloride (BENADRYL), which she didn't take, it was weird. All this subsided and she felt fine afterwards. Last night she felt very fatigued when walking around the house. This morning when she woke up she felt very, very, very fatigued. Walking took a lot of effort out of her. It is hard to explain, but people say this was how they felt when they had Covid. She felt very lethargic and very tired. Patient still had a lingering headache, but nothing like she felt earlier this morning. It's not terrible, but it wasn't pleasant for a couple of hours. Patient was unable to provide seriousness for today's events (08Jan2021), and stated it wasn't really life threatening, but more significant than yesterday. Patient denied having any other vaccines the same day or 4 weeks prior. No history of problems or adverse events with vaccines in past. Pfizer Covid-19 vaccine with events were reported as related.  Events did not require a visit to emergency room or physician office. Outcome of severe aches, voice very raspy, headache/lingering headache, wiped out /fatigued/tired were not recovered; outcome of lethargic, it took a minute for her to catch her breath, flushed and itchy was unknown, and outcome of other events were recovering.
