AE(s) following prior vaccines were reported as none. Stated that, he was not allergic to anything he knew about as he got his shots as a child and they gave him some in the military with no reactions. Prior vaccinations within 4 weeks were reported as none. It was reported that, after 2 hours of being on hold, the patient received the covid vaccination on 13Jan2021 and the second dose on 03Feb2021, both were Pfizer. Stated that, the patient knew that his co-workers mentioned swelling of the lymph node glands. Stated that, to him, it's been over a month since he got the second shot. This morning all of a sudden, the left side of his jaw next to his ear was swollen. He enquired, could it be a side effect even though it's been a while. Stated that, he took an antihistamine and it has gone down some. It was painful and he had discomfort when he ate. He stated that, to him quite a bit of time has passed and he did not think that, he should be having these symptoms. Today, his left side close to his ear by his jawline was swollen up. He was wondered whether this was normal and enquired if he can still get side effects even after quite a bit of time. Stated that, he did not had a fever. This was the only thing that he had was he was swollen up. He was not allergic to anything. He was about to eat breakfast today, on 22Mar2021, he ballooned up by 1/2 to 3/4 of an inch. He added, when he saw himself in the mirror, he can it out to where he can see the swelling on the left side of his face, it was pretty obvious. Stated that, on 03Feb2021, he went for his second vaccine, his follow up vaccine and with his second vaccine, he experienced most of the symptoms that he had with the first vaccine, but they were a little bit stronger. He verified, both vaccines were in his left shoulder/let arm. This time, the metallic flavor on 03Feb2021, did not last as long. He also experienced a headache. He mentioned that, he has had migraines and sinus infections before, but this was just a strong headache. The headache lasted about a day and a half. Injection site soreness, after the second vaccine, the site soreness completely went away. 20 to 30 minutes after his shot was when it start and it lasted about a day and a half. Stated that, he didn't take any medications. The only thing else he took was one a day Vitamins because sometimes his diet was iffy because sometimes he works a lot, sometimes he didn't. His schedule gets chaotic, so he wanted to make sure that he at least has a baseline and have peace of mind that he was getting what his body needs. So, he would rather take a vitamin and play it on the safe side and nature's bounty Probiotic which he had been taking for about 7 or 8 months to help his stomach. Stated that, with the second shot, he had similar symptoms but just a little bit more intense symptoms than what he experienced with the first vaccine. Stated that, unfortunately he knows that Pfizer was swamped, there were 46 people waiting and it takes so long to get through to people. He understands that, it was a public health crisis and there was a lot going on. Stated that, about left side close to ear by jaw was swollen up started today around 10 am (address) time. Some of the inflammation has gone down but he still noticed swelling. Stated that, he said he was about to eat and as he went to take first bite, the pain hit him and he felt it swell up, pain while opening jaw was almost instant. This threw him off because all he did was get up and shower and make breakfast. He stated that, he had gotten full night sleep and he was working evening shifts, got off work and slept till 8:30 am until he was rested and as he was fixing to eat, he just felt pain while opening jaw and touched his face and felt his face swelling. Stated that, swelling was visibly obvious and he still had it. Stated that, on 22Mar2021, it was uncomfortable when he tried to eat and moves his jaw. After talking and eating, it was painful and uncomfortable. He stated that, it was not really hurting right now and some swelling has gone down so he was not that alarmed. Stated that, he thought he was fine and continued to use an N95 when interacting with the public. Stated that, he took off his mask to start eating and felt swelling today when he went to eat. He checked the mirror and checked some things online to see whether he could get hints to see what was happening. He saw that, people were still experiencing side effects even a month after the second shot, so he decided to find out more information before he started panicking and goes to the emergency room. Stated that, he did not know whether to go to the emergency room or not. He was told that, he can still experience side effects from the shot, even with the time that has passed, but he wanted to call Pfizer for ease of mind to see whether his symptoms should go away or if he needed to be checked out at the emergency room or something. However, he did not want to overwhelm the services that are already drained if it was not necessary. Stated that, the only thing else that happened on the same day of receiving the vaccine was the metallic flavor in his mouth. He compared it to when a person was receiving a CAT scan or something and they gave an injection and the person gets a flavor in their mouth. It was like that. He got home and by the time he got home from his injection, the flavor was in his mouth. He was drinking water and juice and the metallic flavor was still there. He thought this was just normal since COVID makes people lose their sense of taste, so maybe the metallic flavor was a reaction. He stated that, if it was something else, he would expect that he would have other adverse reactions. Stated that, he was reading up on other possibilities and everyone was like, you have a slight fever and other discomforts. Stated that, he did not get all of that all he got was swelling and the pain associated with the swelling. Stated that, he took an antihistamine to try and help with the pain and swelling that he got, and that was what probably helped with getting the swelling down. He clarified that, the antihistamine he took Excedrin Pain Reliever with Aspirin. He clarified that, the bottle says Acetaminophen 250 mg-Aspirin 250 mg-Caffeine 55 mg. He just took one. He did not take anything else because he did not know how anything else would react to the actual shot. Stated that, the reason he was called Pfizer was because he knew some of his coworkers that got the second vaccine and a week later, they had swelling of lymph glands/nodes and their neck was pretty swollen. So, he didn't know whether it had something to do with what he was experiencing even though it has been a while. The caller stated that, he didn't had any medical history or conditions that would explain swelling. Caller declines to declined to file a report on his coworkers because he did not know if it was the Pfizer vaccine they received because it has been mixed, everybody he works with just gets something so he was not sure which manufacturer of the vaccines his coworkers. Stated that, he wanted to be safe and get it as soon as he could, so he received his vaccine to be safe. Stated that, he was one of the first groups sent from his job to go get the injection. He was fortunate to receive the Pfizer and not Moderna. Stated that, he had not been sick or anything. Since symptoms were so mild, he was just taking the antihistamine Excedrin for mild symptoms. From there, he had just been lucky enough not to go to the hospital because he knows the last month (address withheld) were at capacity. The AE(s) did not require visit to emergency room or physician. Reporter seriousness for the resulted events was reported as unspecified. Treatment was received for the events left side of my jaw next to my ear was swollen/ballooned up by 1/2 to 3/4 of an inch, pain while opening jaw/uncomfortable when he tries to eat and moves his jaw.
