headaches; dizziness; nausea; vertigo; physical therapist says he getting better at his balance but it doesn't cure dizziness; This is a spontaneous report from a contactable consumer. This consumer reported similar events for four patients. This is the first of four reports. A 74-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 2, via an unspecified route of administration on 30Jan2021, at the age of 74 years, (Batch/Lot number was not reported) as DOSE 2, SINGLE for covid-19 immunisation. Medical history included type 2 diabetes mellitus from an unknown date and unknown if ongoing: Additional Information: about 12 years ago and cardiac operation from an unknown date and unknown if ongoing: Additional Information: about 6 years ago. There were no concomitant medications. The patient received first dose of COVID vaccine BNT162B2 at the age of 74 years on 09Jan2021 for COVID-19 immunization. The patient asked if there were any studies being done on the long term effects of dizziness with the vaccine. The patient's wife reported that her husband began getting headaches, nausea, and dizziness two months ago. They have visited several specialists who cannot determine anything wrong. The patient's wife stated about 2 months ago, her husband started getting dizzy and they have been going to all kinds of specialists, had an MRI, EEG, heart monitor, carotid artery test, went to neuro-ophthalmologist and nobody can find anything wrong. They are both concerned. He's having headaches, vertigo and sometimes nausea; he hasn't passed out. It seems like the common denominator was the Pfizer vaccine. She was wondering if there is any studies being done on side effects like long term. She states her husband has never passed out, he just has constant dizziness and headaches, he's been to two different ENT doctors, a neurologist, a cardiologist, a regular doctor who did blood work, an ophthalmologist and they recommended to neuro-ophthalmologist. They have been to every doctor, they have been to the ears nose and throat and they said its not ears; eye doctor said it's not eyes; neurologist said it's not his brain. He wore a heart monitor for 2 weeks and they will be having a teleconference with the cardiologist tomorrow for results. He just got the heart monitor off Friday. Even though they haven't spoken to the cardiologist yet, he said if they don't hear anything its fine, so she thinks if there was a problem he would have gotten in touch with them already. They will know more specifically tomorrow. It started with dizziness. About 2 months ago he started getting dizzy, but it would only last maybe 10 seconds then would go away and then it got more and more frequent so they went to the ENT doctor thinking it was crystals and went in for a procedure and then that wasn't working so the doctor prescribed physical therapy so he's still going to physical therapy because the doctor said it could be the vestibular nerve. He's been going to physical therapy and he's doing exercises and the physical therapist says he getting better at his balance but it doesn't cure dizziness. He has intermittent dizziness and it was very short lived, like she said maybe he thought it was the crystals but after a few visits they decided it wasn't the crystals, and he had a MRI. She's been driving him, because he's been afraid to drive. In the middle of Jul2021, he got the carotid artery and EEG then had blood work done also in Jul2021 for his primary doctor and everything came out fine. She thinks if there was a problem they would have told them. The cardiologist gets reports everyday from that heart monitor, he wore it 24 hours a day, it looked like a phone. Headaches have been in the last week. When he first started getting these dizzy spells, they only lasted a few seconds, he was driving and he got scared when it would happen when he was in the car so he decided he wouldn't drive, then they started lasting for an hour, these dizzy spells; then its been getting progressively worse, they will last for hours and he will feel dizzy. This past week he started getting headaches and they've been lasting. He has tried Tylenol, Advil, Aleve and nothing gets rid of these headaches. He had a headache when he wasn't dizzy, and when his headache went away, he started getting dizzy again. She needs to stand by light, she might have to get a magnifying glass. He's going to see the neuro ENT doctor, they are going to see Wednesday. The neuro ophthalmologist recommended the neuro ENT doctor, they have been trying everything. The outcome of the events dizziness and headaches was not recovered, nausea and vertigo were unknown while balance disorder was recovering.
