thought maybe he had Lyme disease; Almost passed out a couple of times; Felt a little fever-ish, flu-like at first; he lost weight/he lost 20 lbs; He states it turns out he did have a minor sinus infection; his total body just felt so horrible, like he was dying; lightheadedness/he was so dizzy; sodium was slightly low; felt a little fever-ish, flu-like at first; allergies; This is a spontaneous report from a contactable consumer (patient). A 60-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration, administered in left arm on 22Apr2021 at 10:00 (Batch/Lot Number: ER8735) (at the age of 60-years-old) as dose 1, single for COVID-19 immunisation. Medical history included neuropathy in his feet and in his legs as well, autoimmune disease and carpal tunnel syndrome. Concomitant medications included fish oil and colecalciferol, menaquinone-7, phytomenadione, retinol palmitate, tocopherol, tocotrienols nos (VITAMIN D COMPLEX); both taken for an unspecified indication, start and stop date were not reported. The caller stated he had a reaction to the Pfizer COVID-19 vaccine. The caller stated he has been going through living hell since it started. He had his first injection at the end of Apr (22Apr2021) and his second one at the beginning of May (13May2021). He stated his condition has worsened and has been escalating. He has seen multiple doctors and it's all coming back to the vaccine. He stated he is about ready to jump off of a bridge. He stated unfortunately he is in a really bad way, and he is not getting any better, he is getting worse. He is out of work and he really needed help as to what to do. He stated they tried giving him 5mg Prednisone and it was making him even worse, it's just horrible. The patient mentioned his symptoms started relatively mild, he felt-flu-ish, like he had the flu in 2021. He mentioned he lost 20lbs and is now 200lbs. They thought maybe he had Lyme disease, he was tested multiple times for that. He then thought he had maybe he had really bad sinus allergies, like a sinus infection. He stated it turned out he did have a minor sinus infection and was given antibiotics, but he is 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. He clarified it was like his total body just felt so horrible, like he was dying. He had no appetite, he lost in appetite back in Jun-ish. He went to the hospital last Thursday (date unspecified) 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 has a border collie dog and he tried to let his border collie out for a walk, but he was so dizzy, he had to lay down. He mentioned he almost passed out a couple of times that day. He mentioned he has been checked out multiple times. 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. Patient clarified he was not hospitalized. He went to the Emergency room at 10:00 and was there until about 21:00 (date unspecified). 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. 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.  Caller clarifies 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 didn't remember if these symptoms began after the first or second dose. When attempting to clarify if he was currently suicidal since he made the statement he is about ready to jump off a bridge, the caller responds that he is not. He states he would be lying if he said it hasn't entered in his mind, but he would not hurt himself. He has a wife, a dog, loved ones and he doesn't want to leave this planet. He stated he is in a very bad way, and he believed it was life-threatening. The patient reported that he received his second dose of vaccine on 13May2021. He stated when he was tested back in early 2021 or latter 2020, he was ANA positive. The events resulted in Emergency Room and Physician Office visit. Outcome of events was unknown.
