affects her vestibular system; can't make quick movements with her head or do any bending or turning/couldn't even sit up in bed she would just fall back into bed; ear problems; She feels like her balance is on a rocking boat or a floor that's moving/mess up her balance; She had imbalance problems, vertigo and dizziness/Her doctor has diagnosed this as positional vertigo; This is a spontaneous report from a contactable consumer (patient) from a medical information team. A 72-years-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 1 via an unspecified route of administration, administered in arm left on 09Feb2021 (Batch/Lot Number: EN6201) as SINGLE DOSE for covid-19 immunisation. Medical history included she did start getting a ringing in her left ear about 6 months ago. Concomitant medications included VITAMINS NOS. Caller received the first dose of the Pfizer vaccine on 09Feb2021. The second dose is scheduled for 02Mar2021 (lot number: EN6198) on left arm. She did ok for a few days after she received the Covid 19 vaccine. Caller started to experience some symptoms one week on 16Feb2021 after receiving the first dose of the vaccine which continued and are still persisting. She had imbalance problems, vertigo and dizziness. She guesses it affects her vestibular system. She had real bad spinning. She couldn't even sit up in bed she would just fall back into bed. She had to stay in bed. She reports it took a while to get in to see a doctor and to get therapy. Her doctor has diagnosed this as positional vertigo, but she said she never had it before. So she went to see a therapist and has been going to therapy for about 5 weeks. She started therapy on 04Mar2021. The therapist did the Epley's maneuver and that got rid of the spinning. But she still has bad balance. Her symptoms haven't gone away and she's had them for about 7 weeks. She's concerned and she thought therapy was helping and she was improving but yesterday morning she felt real bad again and she had to stay in bed again. She doesn't know why it comes and goes and it never goes away completely. She feels like her balance is on a rocking boat or a floor that's moving. And she can't make quick movements with her head or do any bending or turning. She's been going to therapy but she doesn't know why all of a sudden it comes back worse again. She can't really do normal things. She's seen where young people are having trouble. The Covid 19 vaccine must mess up her balance and must cause some kind of ear problems. She wishes she hadn't of gotten the Covid 19 vaccine, but she thought because of her age she should have. She's worried. She went to her doctor and he didn't know what to do. Her primary care doctor suggested she go to therapy. She figured she would have some symptoms with the Covid 19 vaccine but her symptoms came later. It took her this long to realize her vertigo and balance problems might have come from the Covid 19 vaccine. But the problem is, she was looking at a website and she found that lots of people are having these side effects. Caller read some information online and noticed people have been reported imbalance and dizziness problems after receiving the vaccine. She thinks it was a mistake to get the Covid 19 vaccine. She read that some people are getting ringing in their ears. She reports that the ringing in her left ear was there prior to her receiving the Covid 19 vaccine and she doesn't think the ringing has changed any. When she had the real bad spinning the doctor thought it was positional vertigo and that was in her right ear. She thought about asking her doctor for an MRI but other people she read about said the MRI didn't show anything. She only went to her doctor's office. When she felt the worst she didn't feel like going to the hospital. She reports her husband had the same Covid 19 vaccine and he didn't have any trouble with it. Caller wants to know if these symptoms are associated with the vaccine. Also how long can the symptoms last since it been several weeks she's had them? The duration of protection against COVID -19 from the vaccine is unknown at the moment. For event vertigo positional, patient visit physician office. Treatment received for events balance disorder and vertigo positional. The outcome of the events balance disorder and vertigo positional were not recovered. Outcome of the other events was unknown.
