A patient of unspecified age and gender received second dose of bnt162b2 (COMIRNATY, Solution for injection, Batch/Lot number: FG3527, Expiry date, NDC number, UPC number was not reported), via an unspecified route of administration, administered in Arm Left on 08Nov2021 as dose 2, single for covid-19 immunization. The patient medical history and concomitant medications were not reported. The patient previously took first dose of bnt162b2 (COMIRNATY, Solution for injection, Batch/Lot number, Expiry date was not reported), via an unspecified route of administration on an unspecified date as dose 1, single for covid-19 immunization. Reporter stated, Okay, so after taking the Pfizer which is my second dose on Monday 8Nov. I experienced pain in the arm at the location of the shot left arm, it wasn't bad it was, moderate and then the next day it got worse but then I started to get the typical side effects that you read about. I got the chills, I got a very light or a low fever but I had an elevated body temperature, fatigue that was day 2 and day 3. I did got, I was feeling significantly better and I felt like this is the end of it, I was fine I thought but then when I woke up on day 5, I not only had fatigue but a lot of brain fog and then I noticed a dull ache on my lower left side by body down by my kidney and I knew I didn't sprained my back. I didn't have any back problems and it is just the left side that's the same side that I got the shot on and then the not much after I noticed, that I think day 4, it was the morning of day 4, I woke up and I am like why it's my lower, it wasn't a strong pain it was a dull aching, sort of light pain to the indistinguishable almost at first but as the day went on, I realized that there is something wrong there. The next day that same dull pain was a little bit more intense definitely did not go away and it was indistinguishable strong like the pain was like it might be couple hours in a day where I almost forgot it was there and then it would get worse there is no specific time that it would get worse it's just was (Incomplete Sentence). So, I started reading about it and I have never had any issues with my kidneys. I have no underline kidney disease at all, I have been a pretty healthy guy in general but I felt like it was something to do with my kidney in it and its correct because it was coming from my lower left side of my back right around the kidneys. It sounds like I have a kidney infection you know, is it the direct result to the vaccine (Intent: General Statement) I don't know but I have a hard time explaining how also I could have gotten it considering it showed up pretty quickly after and I had no other reason to have that. So now, I am now I don't know how many days I got the shot on Monday the 8Nov sometime in the late afternoon and it is now that would be 8Nov it's not 14 so it's what a full week it has not gone away, in fact I just had to call on sick for work and my plan is to see a doctor tomorrow and see if I am looking sick and test it that. So, the other symptoms that I got you know, the light fever and the chill suddenly lasted about a day and a half but fatigue that's still there whatever it's hard to tell, but I think that it might still be there some but the other symptoms are gone, the brain fog is gone but the lower kidney pain is not gone and some fatigue is still there and so that's what I am concerned about so before I go any further, can I get a Case from you on this. Can you give me a case. Further stated, No, I don't want any of my personal information that's important to me you know my issues all that I have and then I want that on the record so the people can be warned about it and I would seek my own good medical advice. The clinical outcome of the events a lot of brain fog was recovered on an unspecified date in 2021 and rest other events was not recovered.  No follow-up attempts are possible. No further information is expected.
