Additional information: Caller stated there has been no vomiting or fever. Caller has had IBS for years and eats a gluten free diet. This is the only symptom that is still lingering. Caller inquired have other people experienced this Because caller scheduled in 3 weeks to get another one, should I be extra precautious for the 2-3 days after the next vaccination incase its worse, how long will it last, Is there a silver lining to all this that our immune systems are properly prepared if we get the virus. Question was asked Is there a silver lining to all this that our immune systems are properly prepared if we get the virus. Caller declines to make a report and does not have wife's card at this time to provide information from. Caller states he is sure it was the same bottle and batch as he received. Caller states he and his wife got the vaccine in last Monday 22Mar2021 together within minutes of each other around 2:30pm. Caller states they both had varying side effects. Caller states they lingered for both of them and continued and even now and he wants to check to see if these have happened to other people and if he doesn't need to be alarmed and let it run it's course. States they both had a sore arm, he had chills and muscle aches that started about 5-6 hours after and went for about 24 hours. Caller states his wife got headaches and she did not get headaches in the past and was very tired and was sleeping a lot. About 48 hours after, not the next day but the day after they both got GI symptoms. Caller states he has IBS and GI issues so it is not unusual for him but states his wife had a normal intestinal tract and can handle anything. States it was a queasy stomach and cramping, not nauseous. Caller provides his wife was regular to say the least, she was more on the backed upside. States not regular for 3-4 days is quite unusual. Caller provides that they don't eat the same as he is on a gluten free diet with his problems so he does not feel it is diet related and easily dismisses this. Caller states he thinks it is a coincidence that a couple days following the shot especially in his wife case that it would be a little suspect of the shot if it was just him but at the same time he finds interesting. Caller provides for the most part he is feeling about right where he was prior to the shot, and because of his stomach issues he had a colonoscopy that came back clean a few months ago. Caller states he is confident it is not a GI tract problem. States it erupted in both of them along those lines and if they go to urgent care with this he has no idea what they would do. States the symptoms are a grumbly stomach and then go and are fine and then it gets grumbly again and they go again. States it's nothing gas it's just odd. Caller declined to make a report for himself or his wife stating he is not looking to get involved in scientific research.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
