fever; am achy; It was burning and swollen between my elbow and arm pit on the side I got my shot but no redness.; It was burning and swollen between my elbow and arm pit on the side I got my shot but no redness.; It felt like someone was holding a match under my arm.; my index finger was swollen and had a knot.; The next day it moved to the next finger and had a knot between the knuckle and palm knuckle.; This is a spontaneous report from a contactable consumer (patient). A 63-year-old female patient of an unspecified age received bnt162b2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE Solution for injection Lot Number: ER2613) via an unspecified route of administration in arm left on 17Mar2021 12:15 as dose 1, single for COVID-19 immunisation. Medical history included breast surgery from an unknown date and unknown if ongoing caller states in October she was going for a routine check up and 6 days later had surgery for a breast check, pneumonia from an unknown date and unknown if ongoing history of 13 pneumonia. Concomitant medications were not reported. The patient previously took tylenol. On an unspecified date, the patient experienced that I had a fever and am achy (which I dont care about it). My normal temperature was usually 97.8 but I have a low grade fever and did not come until about 1 hour or so. I got the vaccine at around 12:15 and asked that can you take aspirin and Tylenol. I got my vaccine last Wednesday and had a couple little weird things which was not unusual for me. I had already called Pfizer because I had a fever and I wanted to make sure I can take Tylenol. On 18Mar2021, a day after that my index finger was swollen and had a knot. The next day it moved to the next finger and had a knot between the knuckle and palm knuckle. On Friday I ended up with a very strange thing under my arm where I got my shot. It was burning and swollen between my elbow and arm pit on the side I got my shot but no redness. It felt like someone was holding a match under my arm, on her right hand in her index finger the knuckle between her palm and the first knuckle swelled and she got a little tiny knot that felt like a marble. Caller states she got the Pfizer COVID Vaccine on Wednesday and then last Friday 19Mar2021, she was going to call and thought surely this was a fluke and then thought it may just be due to the Pfizer COVID Vaccine. Caller stated she was a retired librarian and retired due to COVID and she knows research was important. Caller stated that on her right hand in her index finger the knuckle between her palm and the first knuckle swelled and she got a little tiny knot that felt like a marble which happened the day after the vaccine on Thursday. She stated that she woke up on Friday and the knot had kind of gone out of her index finger and she had no idea why that would be and thought dear God why this was happening and then this moved to her middle finger the next day on 19Mar2021 which was the day after her index finger started swelling. Caller states the flesh between her palm and 1st knuckle had swelling and it was not ongoing but by the next day she would say not all the swelling had gone but she would say 85-90 percent of the swelling was gone; states her index finger was back to pretty much normal and the swelling was coming down. She was sick for three years and knows what swelling was and this swelling she had in her finger was not huge but was strange but the next morning that finger was still a little bit swollen and then moved to her middle finger swelling and it had not gone down on the index finger but the swelling was definitely down and no longer had the little marblely thing; states there was a marblely thing in her middle finger and that was the right hand and the middle finger was swollen. She always seems to have bizarre things and slept 12 hours on Tylenol 3 and does not take codeine and that was her history; caller states she had no lot numbers, expiry dates or NDC numbers to provide for the Tylenol 3 and states she did not taking it for the COVID Vaccine but it was decades ago and the Tylenol 3 had nothing to do with this and it seems to be something odd and stated that if she had to have surgery they wake her up yelling her name and nothing goes quite smooth for her medically; states she was just mentioning the Tylenol 3 because it always seems to be an odd thing and had nothing literally to do with this. In October she was going for a routine checkup and 6 days later had surgery for a breast check and states she knows she was getting older; no further details provided by the caller. On Sunday after getting the Pfizer COVID shot, in her left arm between her elbow and her armpit on the underside all of a sudden on the same arm as her vaccine, right between basically her elbow and her armpit, it swelled up a little bit and felt like she was hovering over a match and it was burning but not red, she was concerned with the burning between her elbow and armpit on the underside of her Pfizer COVID shot area. The patient underwent lab tests and procedures which included body temperature resulted as 97.8 on an unspecified date my normal temperature was usually 97.8. The clinical outcome of the event was unknown.  No follow-up attempts are possible. No further information is expected.
