This is a spontaneous report from a contactable consumer (parent, patient's mother) via a Pfizer-sponsored program. A 55-year-old female patient (reporter's daughter) received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection) via an unspecified route of administration, administered in right arm on 01May2021 (Batch/Lot number was not reported) (at the age of 55-years-old) as dose 2, single for COVID-19 immunisation. Right arm because of cancer the patient can't do the left arm. Vaccine was not administered at military facility. Medical history included ongoing anxiety. Concomitant medication included lorazepam (ATIVAN) taken for anxiety, start and stop date were not reported. Historical vaccine BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection) via an unspecified route of administration, administered in right arm on 10Apr2021 (Batch/Lot number was not reported) (at the age of 55-years-old) as dose 1, single for COVID-19 immunisation. The patient had no prior vaccinations (within 4 weeks) prior to the first administration date of the suspect vaccine. The patient had no adverse events (AEs) following prior vaccinations. On 03May2021, after the second dose of the Pfizer Covid-19 vaccine, the patient started to have complaints of a severe headache, felt like her head was going to explode, ringing in the ears, and pressure in the ears. The patient has been to several healthcare professionals (HCP's) and has been grinding her teeth for two months, wears a night guard, and thought to have Temporomandibular joint (TMJ) disorder. Caller states that they don't know if her daughter could possibly have ear nerve damage. Caller is asking if severe headache, ringing in the ears, pressure in the ears, and nerve damage are side effects of the Pfizer Covid-19 vaccine. The headache caused severe pain. She feels like her head is going to explode and sometimes gets cracking noises in ears. The patient has gone to the emergency room twice but was not admitted to the hospital. The emergency room took tests and did not find anything. The patient was given a cocktail at the emergency room. The cocktail took care of the patient for two hours and knocked the patient out for a couple hours. The patient is having the same problems. Headaches have improved, the only thing that has improved. Ringing in ears and pressure in ears are both persisting. Feels like head is going to explode has improved somewhat. The cracking noises in the patient's ears are not constant like they were. The patient was sent home with pain medication she could not take. The patient does not handle the medication well, the pain medication made the patient very sick. The patient is also on anxiety medication three times a day now to get through the day. Caller clarifies the patient did take the pain medication for about a week. The patient went to a neurologist. The patient is also on anxiety medication three times a day now to get through the day. She takes Ativan one quarter of 1 mg, three times a day. The patient was taking more but was jittery and has cut back to one quarter of 1 mg three times a day. Takes one quarter of 1mg Ativan late at night to sleep. Caller began taking the Ativan right after symptoms began after receiving the second dose Pfizer Covid Vaccine. Caller states her daughter went to her primary care doctor, an ear, nose and throat specialist. The ear nose and throat specialist checked the patient for sinus problems and did not find anything. She also had 2 facial computed tomography (CAT) scans, magnetic resonance imaging (MRI), and had a lung scan. The patient went to a neurologist who studied the report and did not see anything. She has been to a neurologist and an ENT specialist, but no one has been able to confirm anything about her daughter's symptoms. The patient grinds her teeth so she went to a dentist and had a mouth guard made because thinking the patient may have TMJ. The patient has been wearing the night guard for two months with no improvement. The outcome of the event severe headache, felt like her head was going to explode was recovering; for pressure in the ears, ringing in the ears/cracking noises in ears, and grinding her teeth was not recovered, while for the rest of events was unknown.  The lot number for the vaccine, BNT162B2, was not provided and will be requested during follow up.
