trigeminal neuralgia; strange pain that started happening in her head; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the patient.  A 74 year-old female patient received bnt162b2 (BNT162B2), administered in arm left, administration date 05Mar2021 (Lot number: EN5318, Expiration Date: 31May2021) at the age of 74 years as dose 2, single for covid-19 immunisation. Relevant medical history included: "Sjogren's" (ongoing); "Autoimmune issues" (unspecified if ongoing). Family history included: "Rheumatoid arthritis" (ongoing), notes: On her mother's side her brother and sister had rheumatoid arthritis. There were no concomitant medications. Past drug history included: Flu shot for Immunization, reaction(s): "glands swelled up", notes: several years ago she had a flu shot and it seemed like her glands swelled up; Polio shots for Immunization, notes: She had polio shots when she was a kid and her body is pretty accepting of this kind of stuff. Vaccination history included: Bnt162b2 (Dose: 01, Lot Number: EN5318 , Expiry: 31May2021), administration date: 12Feb2021, when the patient was 74 years old, for Covid-19 immunization. The following information was reported: TRIGEMINAL NEURALGIA (non-serious) with onset Mar2021, outcome "recovering", described as "trigeminal neuralgia"; HEADACHE (non-serious) with onset Mar2021, outcome "unknown", described as "strange pain that started happening in her head". The events "trigeminal neuralgia" and "strange pain that started happening in her head" were evaluated at the emergency room visit. Relevant laboratory tests and procedures are available in the appropriate section.  Additional Information: Caller received second dose 05Mar2021. One week after second dose "symptoms started happening" in caller's head, after two weeks she presented to the ER and received a diagnosis of trigeminal neuralgia. She had her 1st COVID shot in Feb2021, she had her 2nd COVID shot on 05Mar2021 and she did have something that happened after that which she thinks that she blamed on the shot but she doesn't know for sure if it was from that. Let's just say she ended up in the emergency room with having her brain scanned one day, twice and she was also wondering if this question has been asked by other people, she doesn't know. Now she does want to say she is just curious about all of this. She really doesn't want to believe that she has autoimmune issues. She is going to wait until Apr2022 when she was supposed to have more blood tests done. When she discussed this all with her doctor and asked if it could be fixed her doctor said no. She just would like to have some information and she is not going to sue anyone. She made the decision to have the vaccines. After her 2nd dose she didn't know if she was going to get her booster or not since all of a sudden she now has trigeminal neuralgia and she doesn't believe that she has that either but she does have it. She is just a curious person. She also wants to know if this has happened in other people. She is not out to go and point fingers she just wants to try to find out information about what happened with her. The hematologist said in reports that she had thought this was occurring because of the caller's Sjogren's and rheumatoid arthritis, which the caller still questions. Event Details: She confirms that she had two brain scans a week and a half after she had her 2nd dose. She had a strange pain that started happening in her head and she had waited a week before going to the emergency room. She was at a woman's breakfast and she knew that when she got done with the program that morning that she was going to go down the street to the hospital because it was not normal for her to have pain in her head. They took her right in and she got the scans and they told her that she had trigeminal neuroglia which they don't say what to do about it. She still has it, but it is not like it was that day. She has had 2 more scans and later on they were looking at her carotid arteries which are perfectly fine. The emergency room doctor at the time wrote in his notes, which always makes her concerned, "I made sure that I told the patient that she has an abnormality on the right side and the pain is on the left side," the caller doesn't know what that means. She confirms this was in Mar2021, she still has it now but it has gotten better. History: Inquired for Sjogren's and rheumatoid arthritis diagnoses dates and she says that she doesn't actually know, but its in her records. She will say last week she did see a swallow doctor and she was having tests done. The 1st thing that this doctor said to her was asking how her Sjogren's was and asking how her rheumatoid arthritis was. She was amazed that he knew this. The only good thing about that was that he gave her more knowledge about that and he was helpful otherwise she was just floundering with it. Her provider keeps saying put eyedrops in, take lozenges, gargle and that she needs to see a rheumatologist but they don't want her to travel for that so they keep testing her for it and are looking for something until her doctor can talk to her about her having it and what to do about it. She is not out to get Pfizer but if this has happened to other people even if they don't have these autoimmune situations, then is it the vaccine. It is just complicated. She was not provided with the lot number and expiry date.  Every year she gets a flu shot and back a couple of years ago or several years ago she had a flu shot and it seemed like her glands swelled up. She went and had a test and they lost her results so she doesn't know. Except that one time she has never had anything. She had polio shots when she was a kid and her body is pretty accepting of this kind of stuff. Family Medical History Relevant to AE(s): On her mother's side her brother and sister had rheumatoid arthritis but she doesn't think any of her brothers have any of this stuff.  No follow-up attempts are possible. No further information is expected.
