yesterday I got a really, really bad headache, that I still have; sore arm; This is a spontaneous report from a contactable consumer (patient). A 67-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE; lot number: EL3246), via an unspecified route of administration in the left arm on 06Jan2021 at a single dose for COVID-19 immunization. Medical history included lung condition, sarcoidosis, immune system problems, ongoing headache and migraines. Concomitant medication included topiramate for headache and to ward off migraines. States it is in a white bottle, but a pharmacy bottle from (Pharmacy name). She provides discard after 18May2021. Now clarifies it is Topiramate, the generic, 50 mg, it helps ward off migraines. She sees a neurologist for this, not by her internist, she sees the internist who prescribes it twice a year, actually, it is so her headaches don't turn into a migraine, this is just a worse headache, she doesn't know what this is from, hopefully it will just get better. The patient previously took codeine and experienced drug allergy. It was reported that she received the first dose of the vaccine on Wednesday, 06Jan2021. Patient reported that "she's a headache person and gets them all the time." Per the reporter, late yesterday on 10Jan2021, she got a really, really bad headache, that she still have. Could this be vaccine related this far out? The only thing she got right after the vaccine was a sore arm. It's not debilitating (the headache). She is going through a few stressful situations with a friend and her son going through a divorce. She do have a lung condition that's now in remission. She was being followed by a pulmonologist and she is taking something. She is allergic to codeine. She will continue to take Tylenol and will continue to just deal with it." She said that her husband believes the current headache is related to stress. It was further reported that she got the vaccine last Wednesday, on 06Jan2021, she is a headache person, she gets headaches all the time, and takes Topamax (later clarified as the generic, topiramate) on a daily basis, but yesterday on 10Jan2021, late afternoon, she got a really really bad headache, that is still there today, but she didn't get it right after the vaccine, she wondered is that related, or would she have gotten it right away, the headache? States it is not horrible bad, it's just a bad headache, she still wants the second vaccine, and she doesn't want this to interfere, she has a lot of medical conditions, this is why she was afraid to call. Her husband doesn't think this has to do with the vaccine, but she felt like, let her just call. She still has it (headache), she is a headache person, it got better then she got it again, and it also could be stress related, she has been dealing with a few things: she has a friend giving stress, her son is going through a divorce. But she did not get it right after the vaccine, the vaccine was early Wednesday, which is why her husband doesn't think it has to so with anything. Also, she has a lung problem, and thank god she is in remission, she has sarcoidosis, and she has immune system problems, so she has medical reasons. But the issues most important are the lung. She is having blood work done tomorrow, so it has nothing to do with it. States this is good to tell about the stress: she has a friend, a toxic friend, she lives in (State Name), the friend lives in (City Name), and she is a negative person, and she is ending a longstanding friendship, which is not like her, so that is weighing on her mind, and that is, could be, adding to it, and even hurts a little, that's stress, but since she had the vaccine, she thought to call and see. She can definitely get the second dose, right? This report doesn't affect her getting the second dose? After reviewing the call recording, there is no mention of the friend getting the vaccine. The reporter said her friend is giving her stress, and in regards to the statement "weighing on her mind, and that is, could be, adding to it, and even hurts a little, that's stress, but since she had the vaccine", the reporter was referring to herself. Additionally, the statement "But she did not get it right after the vaccine, the vaccine was early Wednesday" the reporter was also referring to herself. The outcome of the event 'headache' was not recovered while unknown for the other event.
