Lyme disease; Felt a little feverish, flu-like; Sinus infection; his total body just felt so horrible, like he was dying; No appetite, he lost in appetite; Lost weight; Lightheadedness/Dizzy; almost passed out a couple of times; sodium was slightly low; This is a spontaneous report from a contactable consumer (patient). A 60-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Batch/Lot Number: EU10150), via an unspecified route of administration, administered in right arm on 13May2021 09:00 (at 60 years old) as dose 2, single for COVID-19 immunization. Medical history included neuropathy, and carpal tunnel syndrome, both from an unknown date. Concomitant medications included fish oil; and colecalciferol, menaquinone-7, phytomenadione, retinol palmitate, tocopherol, tocotrienols nos (VITAMIN D COMPLEX); both taken for an unspecified indication. The patient previously received the dose 1 of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) on 23Apr2021, for COVID-19 immunization. On an unspecified date in 2021, the patient mentioned his symptoms started relatively mild, he felt-flu-ish, like he had the flu. He believed he had the second dose 13May2021 and the first dose on 23Apr2021, he confirmed he was 60 years old then. The patient thought maybe he had Lyme disease; he was tested multiple times for that (unknown result). He then thought he had maybe he had really bad sinus allergies, like a sinus infection. It turned out he did have a minor sinus infection and was given antibiotics, but he was still not getting better. It was like from the reaction he had with the vaccine and taking an antibiotic, it threw his body into worse shape, like a super wharf. It was like his total body just felt so horrible, like he was dying. He had no appetite, he lost in appetite back in June (unsure). He took the antibiotics, and he also lost weight. He went to the hospital last Thursday because he was so lightheaded when he walked. He was pushing his mower across the lawn and it hit him, and he had to lay down for hours. He mentioned his wife was out of town. He has a dog and he tried to let his dog out for a walk, but he was so dizzy, he had to lay down. He almost passed out a couple of times that day. He has been seen by a Cardiologist and his heart is fine. His family physician has seen him at least 2 or 3 times. He had a COVID test while he was the hospital. He was not hospitalized. He went to the Emergency room at 10:00 and was there until about 21:00. They did all kinds of bloodwork and nothing was real revealing. His sodium was slightly low, but this doesn't account for any of his symptoms. The doctors were at a loss. They said they could do an MRI at about 16:00 or 17:00, as he was still in the Emergency Room. He agreed to get the MRI, but then they shifted staff. He has been in contact with a Neurologist, and she thought maybe he had Long Haulers but it's not really adding up to that. The doctor doesn't think it was Long Haulers from his impression of their visit. His symptoms seem more connected with the vaccine. He stated he felt a little fever-ish, flu-like at first, like it wasn't anything. He kept thinking maybe it was allergies and then as it got worse, he thought maybe it was Lyme disease. He had three tests done for Lyme disease. He just was not feeling himself. He clarifies it was within a day or two of getting the vaccine, he felt this way, but he honestly doesn't remember if these symptoms began after the first or second dose. The events required visit to Emergency Room and Physician Office. He states he is in a very bad way, and he believed it was life-threatening (unspecified, pending clarification). The outcome of the events was unknown.
