Caller (reporter) was a consumer calling on behalf of her husband (Patient, currently 43 years old, was 42 years old at time of vaccination, male) inquiring about side effect information for the Pfizer Covid-19 vaccine. Caller stated "my husband was having some side effects from his Pfizer Covid-19 vaccine, I wasn't sure if they are common or if you any remedies for them. Since his second dose, he (patient) had frequent headaches, acid reflux, issues sleeping, but I'm not sure if that's due to acid reflux. His lactose intolerance was still bad. He has had less and less of a desire to eat as time goes on--he is pre-diabetic so she needed to make sure he's eating, he's having some weird chilling at the injection site like putting bengay on it but that's intermittent. He's feeling uncomfortably warm--doesn't have a fever, just feeling uncomfortable hot. He's moodier than before but I don't know if that's symptoms of vaccine or consequence of the acid reflux and lack of sleep, more disengaged than before, withdrawn. We're about a month out from his second dose now. He got his second dose 03Sep2021. He's able to sleep a little bit, but we're not sure if it's because of the acid reflux.Usually does not have to take Lactaid tablets unless he chugs a whole gallon of milk. After the first dose, he had a much more severe reaction to dairy. It was so much he had to call in sick the day following. Had a little bit of cheese on his taco and a dollop of sour cream and it put him out of work. Now he was taking Lactaid tablets at every meal, but he still has dairy issues and they are now worse after getting the vaccine.

After the second dose he has had an increase instance of headaches and now experiences acid reflux, which he has not had before. Having trouble sleeping and not sure if it's related to the acid reflux or if just something on its own, does not know for sure. As time progresses, he has lost desire to eat.

Unable to provide NDC, Lot, or expiry for Metformin. Has been on it a couple of years, not good about taking it for probably the last year but was taking it more regularly now. Later provides he had 3 other symptoms after the second dose. Reporter questioned Is getting chilling effects at the injection site, it's random and pops up, almost like he was rubbing Bengay on it. Felt like his core body temperature has increased, just feels uncomfortably warm all the time now. It may not really be symptoms of vaccine but could be response to all the other symptoms he has, but his mood has changed, he was moodier.
