Headache; lymph nodes are swollen; he felt very constipated the last few days so he took 2 Dulcolax; loss his appetite; burping a lot; really really bad watery diarrhea; he is itching under his arm and around his crotch where his lymph nodes are; his arm was sore; nausea; This is a spontaneous report from a contactable consumer or other non hcp. A 68-years-old male patient received second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, formulation: Solution for injection, Batch/lot number was not reported) via an unspecified route of administration on Feb2021 (age at vaccination 68years old) as single dose for covid-19 immunisation. The patient medical history and concomitant medications were not reported. The patient previously took milk of magnesia for covid-19 immunisation and experienced diarrhoea, bnt162b2 and experienced headache. The patient experienced that in Feb2021 he had headache, lymph nodes are swollen, he felt very constipated the last few days, so he took 2, loss his appetite, burping a lot, really really bad watery diarrhoea, he is itching under his arm and around his crotch where his lymph nodes are, his arm was sore, nausea. Patient is calling about the COVID shot that he received the second shot, he confirms the Pfizer COVID 19 vaccine. He really needs some help he got the second shot 6 days ago. This is the 6th day. He did not have too many bad side effects. he had a headache, and his lymph nodes are swollen and itching they are not really swollen bad, but they are swollen, and he felt very constipated the last few days, so he took 2 Dulcolax, not yesterday but the day before he took 2 Dulcolax in the late afternoon. Yesterday he had a normal bowel movement, then he loss his appetite. He has been burping a lot and had like GI upset and this morning got up and he has really really bad watery diarrhoea and nausea and he just feels lousy all over. He does not know if it is from the Dulcolax or from the COVID 19 shot, he got it 6 days ago and didn't have these symptoms until now, he still has the swollen lymph nodes, and he is itching under his arm and around his crotch where his lymph nodes are, and he is wondering what they suggest. He called his primary care and that is getting nowhere. He called a GI doctor, and he hasn't been there in quite a while, so they don't want to be involved. He does not know what to do if he should get a COVID test. He has not been out anywhere at all in literally like a year. He has not gotten any contact with anyone. He asks could it be that he has COVID? Are diarrhoea and nausea side effects and can they occur 5 days after the shot. Primary Care: He did not get the shot there, he got it from the (Facility Name withheld). He has to be honest it's kind of a disgraceful arrangement, as far as people giving the shot. The quality of the people. Giving it at a ball field is not exactly conducive to feeling confident about it. When you watch tv, they get a shot and they are in a chair, but there they had a nurse completely unprotected and these are people outside and they are massive amounts of shots and he doesn't know if it is getting applied right. It is just not a good feeling of confidence; it was poorly organized. The first time he got the shot he has underlying conditions, including blood thinners, he is on 2 blood thinners. he had to wait 45 minutes after the first shot. The second time they didn't even ask the question, they didn't time anybody they let people pull in by loads of cars and just basically guessed about how long they had been there. They let him go in 10 minutes which was strange they were not at all concerned. There were people sitting under a tree and they were waving people to leave, and they didn't know when people came or anything. They gave him a card and had him back up and he rolled through the waiting area. He knows this isn't a Pfizer issue, but the administration should instil confidence. Product details: He doesn't have the vaccine card with him, he does not remember what he did with it he thinks it is in his wallet. he could get it later if needed for the NDC lot expiration, but he does not have it right now. Dose: Unknown, he made sure they knew it was the second shot. The thing was they were so incompetent there were first people getting shots and second people getting shots. He bets he was asked 4 times in 4 different places if this your first or second shot and he said this is his second shot so when the nurse came over, he asked to make sure, and she said this the second shot because he didn't feel comfortable, but it said shot 2 on it and it said that on the card they gave him, so he assumes they got it right. The only thing is 2 days ago he took Dulcolax late afternoon and now he has diarrhoea. He is thinking he might be sensitive to laxatives because a few years ago he took 1 tablespoon of Milk of Magnesia and had diarrhoea for 3 days. No further information provided. He just feels so lousy and last night his stomach felt bloated he had nausea and threw up at least once maybe twice. Food was just refluxing, and he hardly even hardly ate anything yesterday, his stomach was in nots it was just upset, his digestive system is very upset. He thinks he gave all the information he did have a terrible headache and lymph nodes were swelling and his arm hurt. He had itching in his lymph nodes as well that was pretty much what he had. He confirms the itching was pretty much localized to the lymph node areas. He did not have fever. he didn't have anything else. That's all he had just a sore arm which he had the first time he had sore arm for 1 day, the second time it was a couple more days that his arm was sore. He does not think he had anything else other than the terrible headache that was his only first shot incidents. He clarifies he bad a headache after both the first and the second shot, he has a bad headache right now. The clinical outcome of the event was unknown. Therapeutic measures were taken as a result of he felt very constipated the last few days, so he took 2 Dulcolax.  No follow-up attempts are possible; information about lot/batch number cannot be obtained.
