An 82-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number and expiration date was not provided), via an unspecified route of administration (left arm) first dose on 30Dec2020 10:30 at single dose for covid-19 immunisation. The patient's medical history and concomitant medications were not reported. The patient stated that I had the vaccine back a week and half ago on 30Dec2020 and was due to get the booster this month and wanted to report severe pain arm for two days. The patient stated that he had many vaccine (Unspecified Vaccine) over the years and have never had anything that hurts so bad after about six hours. The patient just wanted to know that was that normal. Consumer further stated, "I took the vaccine about 10:30 in the morning and about four hours later, it started getting sore but that thing was normal you know some vaccines (Unspecified Vaccine) do that but along with that it started hurting about four hours after the vaccine and it continued to get worse and that night I went to bed and I cannot sleep, it hurts so bad. The patient even have thoughts about getting up and go in to the emergency room. It was the worst pain I have ever had and I could not move my arm. I could not sleep on the right side or on a left side and all I did was take Tylenol as prescribed and that helped a little bit but not much but I did not go to the emergency room, I am not going to do that but I felt like it because it hurts so bad but I made it through the night and next day it continued to hurt really bad. I just keep taking Tylenol every four hours and that continued for two days and then finally I was able to raise my arm up above my head without little pain, it was discomfort, but it was not hurting so bad." The patient stated that the event started about two hours later it started, it started hurting and then it continued to get worse and worse and it was severe, that is the reason why I am calling that it was severe. I wanted a shot or morphine to relieve myself that how bad it was." (no clarified further). The patient stated that the vaccine was given in my left arm only about one inch below the top of my shoulder which I think that might have been the problem, I don't know if you can answer that or not but I have never received the vaccine or shot anywhere near that area, it is always three or four inches down in my muscle, on my arm either on left or right, this was given in my left arm but this was given almost in my joint I am wondering if that would cause pain." The patient stated it was given only one inch below the tip above shoulder may be that is causing so much pain." The patient just wanted to report the severe pain, that was for two whole days and then it was subsided and it lasted for four days and I still have uncomfortable feeling in my arm. I was finally able to raise it above my head, my left arm, after two days but it was not comfortable to do it, it was painful." The outcome of the events was unknown.
