This 80-year-old male patient received the second dose of BNT162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Lot Number: UNKNOWN) via unspecified route in Apr2021 (at the age of 79-years-old) as a single dose for the corona virus, to get rid of it/ it's supposed to be sure he didn't get it. Patient had no medical history. There was no relevant family medical history. There were no additional vaccines administered on same date of the COVID-vaccine. Patient had no adverse events following prior vaccinations. He remembers his first polio shot he got that back in the early 50's and his second shot was a cube of sugar, called the salt vaccine. Stated he's been getting vaccines for a long time and he never had any trouble with any of them. The patient previously received the initial dose of the BNT162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE) in 2021 (March or April) in the left arm which was deemed invalid by the vaccination provider due to temperature related issues (i.e wasn't cold enough). He explained he received a letter informing him of this incident and recommending a replacement dose (which he thinks was on 06Apr2021). About 2 to 3 weeks before he got his first COVID shot, he got a flu shot in his left arm, about 4 or 5 inches above where he got his COVID shot. The patient's concomitant medications were not specified. He reported that the second vaccine (BNT162b2) caused him problems. On 06May2021, he woke up with his right wrist twice as thick as his left one, it was swollen real bad. The right wrist was quite sore and painful. He didn't know if he was getting carpal tunnel or what it was, so he went to the ER about it and they gave him three different kinds of pills, two of which included tramadol 50mg one every day and ibuprofen 400 mg. The ER couldn't determine the cause for his reaction. About 3-4 days after taking the prescribed medication, his reaction subsided quite a bit and was not nearly as hurtful, but his left wrist then started swelling and being painful/sore. Therefore, he continued to take his medication and it improved. It was like that for a couple/ three days, and it calmed down. He thought he was okay 2-3 days ago, but this morning (14May2021), his right shoulder was swollen and pretty sore and was getting worse; he was in so much pain, so sore he could hardly even move his arm, he couldn't pick it up straight in the air, couldn't get his elbow up past his ear. The patient also reported that when he got off his bed, his left knee was sore and it felt like a fire underneath his kneecap and he was having trouble walking. The left knee was swollen real bad and was hotter than a firecracker. Thus, he went back to taking his pill again. The knee pain started the morning  of 14May2021 about the same time it seemed and has worsened, and he took a 400mg ibuprofen and the other pill he's taking, "100 mg doxycycline or something". Patient hadn't been doing much since, he was feeling kind of laid up, he had thought it was all done with yesterday (13May2021). He stated he's been hearing things about allergic reactions to this COVID shot, was sure that a lot of people are having complaints of allergic reactions, and was sure he's not the only one who has had a problem like this. He asked if there was anything he can take to block it because he is sure when this calms down after a week or whatever, it will be his in his right knee or left shoulder or wrists or ankles and he's 100% it's about that COVID shot. He stated he's never had arthritis before. He stated that he has never had any problems like this before. He is supposed to go see his doctor in a week or two. He tried to call the doctor to make an appointment, but he figured he would wait a couple days, but he is hurting bad today (14May2021), and he hasn't been to anybody yet except for the ER. The patient stated it looks like the vaccine is methodically causing this spread into his body. He also reported that it feels warm outside of his left wrist, towards the edge of it and all the way to the joint of the little finger and he thinks the swelling will start again. He expressed feeling anxious about his reactions. He asked if there were any kinds of pills he could take to block the effects of the vaccine from working in his body. He stated it seems like it's going from one area to the next and it seems like it's going through his joints and he doesn't like that. His left wrist still got a little bit of soreness in the back near the joint, but doesn't appear to be swollen. Regarding the right wrist, he has recovered completely, it feels better; doesn't feel any soreness in any place and doesn't look swollen. The clinical outcome of right wrist twice as thick/left wrist started swelling recovered on unspecified date; left wrist painful/sore not recovered; right shoulder is so sore not recovered; left knee was sore not recovered; anxious was unknown; feels "warm" outside of his left wrist/ felt like a fire underneath his kneecap was unknown; left knee is swollen not recovered; arm was so sore unknown; carpal tunnel unknown; trouble walking unknown; right shoulder was swollen was not recovered.
