severe arthritis in his left shoulder;normally can't raise his left arm above his shoulder;can now raise his left arm above his shoulder/bad arthritis in his knees;knees have not been hurting as bad; This is a spontaneous report from a contactable nurse (patient). A 59-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection), intramuscular, administered in the left arm on 13May2021 10:20 AM (Batch/Lot Number: EW0170) (at the age of 59-years-old) as 2nd dose, single dose for COVID-19 immunization. Medical history included arthritis (severe arthritis in his left shoulder; he has bad arthritis in his knees), dengue fever from 2001 to an unknown date (he had Dengue fever twice), cholesterol, diabetes, and gout. Concomitant medications included vitamin D taken for an unspecified indication, start and stop date were not reported; zinc taken for an unspecified indication, start and stop date were not reported; unspecified antacid and unspecified medications for cholesterol, diabetes and gout. The patient previously took Percocet from an unspecified date (over 10 years ago) and it did not have any effect on him. The patient previously received the first dose of BNT162B2 on 22Apr2021 (Lot number: ER8735) (at the age of 59-years-old) at 10:20AM intramuscular injection in left arm. The patient received the vaccine because that was what they said everyone should do. He does not take the flu vaccine, because he does not get sick. He takes Vitamin D 5000iU. In 2001, he got Dengue fever. They say there is no cure for that, but he has a fever. It is an old wise tell, but he drank Sunguni, which is some kind of alcohol in. It did not taste good, but it took care of the Dengue fever. Eight hours later, and it was gone. He was hit by a skeeter. He was sick for three days. After three days of being sick, this old lady was like here take this. He was like well why not, because he was hurting everywhere. Then bam, eight hours later, he was fine. The second time he got Dengue fever, the same thing happened. He is a "Military brat", so he has all of his vaccines. The patient reported that he was just an old guy, fat guy person (as reported). He takes medication for cholesterol, diabetes and gout. He also self-medicates; he takes Zinc 50mg, and Vitamin D 5000iU, and sometimes he takes a typical antacid. The patient reported that he received the second dose of the COVID vaccine last week or the week before. Clarified he received the second dose on 13May2021. He received the first dose of the COVID vaccine three weeks prior to the second dose. He had a surprising outcome. He was hoping that other people have had it too. He has severe arthritis in his left shoulder. He normally takes Ibuprofen like crazy, like boom boom boom (as reported). He normally can't raise his left arm above his shoulder. He had no reaction to the COVID vaccine. He has had no swelling, no muscle aches, nothing. He can now raise his left arm above his shoulder, and he can reach all the way up to the ceiling. He wanted to see if it was true; it has now been five days since he noticed. The next day after he got the COVID vaccine, it started getting better. He noticed about five days ago, that it was completely gone. He has not had to take Ibuprofen in five days. He wanted Pfizer to know that he does drink, and he did not stop drinking this whole time like they told him too. He does not wear a mask. He states, "if a mask cannot keep a fart out, it ain't going to keep covid out". The patient clarified that it began on 15May2021. Every morning, he wakes up and takes a shower. One day it dawned on him that he could lift his hands above his head. It was either 19May2021 or 20May2021, that he realized he could lift his arm above his head. He has had no issues operating a push mover or weed whacking. He feels like he has wings. He asked his doctor if he could get the COVID vaccine in his knees too. He has bad arthritis in his knees. His knees have not been hurting as bad. He feels like the COVID vaccine attacked his arthritis. He has not had to take Ibuprofen for five days now. He was hoping that there was something in the COVID vaccine that might lead to something Pfizer was not planning for. Kind of like Viagra, how it was used for something it was not created for (as reported). He told his doctor to sit a few doses of the COVID vaccine up for him. He wants another dose of the COVID vaccine. He has been swinging his arms all around. He has been climbing on ladders. Normally he was too old of a guy to climb on the ladders. He did not change any habits, including eating habits. The only thing he stopped was taking Ibuprofen. He did not have any reactions to the COVID vaccine. The outcome of "severe arthritis in his left shoulder; normally can't raise his left arm above his shoulder; can now raise his left arm above his shoulder/bad arthritis in his knees; knees have not been hurting as bad" was unknown. The patient reported the causality for the event as: He thinks this is a sign in a positive way. He hopes that this will create new stuff, that there is something in there that might help people, like people with rheumatoid arthritis. He does not take anything. Percocet does not have any effect on him. He does not know why people steal Percocet. Lot number, NDC, expiration date: Unknown. That was 10 years ago. He has a high threshold to pain. He does not feel pain.
