normal headache/Weird Headaches; pressure moving around from side to side and pressure in the back which is not like a normal headache for her; Low Grade Temperature; Tired; achy joints/Joint Achey; achy arm; This is a spontaneous report from a contactable consumer (patient) via medical information team. A 53-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Formulation: Solution for injection, Lot number: Unknown), via an unspecified route of administration in left arm on 08Apr2021 at 16:45 (at the age of 53-year-old) as dose 2, single for covid-19 immunisation at "PRIVACY" county public health. The patient medical history and medications were not reported. The patient did not receive any other vaccines within four weeks prior to the vaccination. Caller was a 53-year-old female consumer who received the second dose of the Pfizer COVID-19 vaccine on 08Apr2021 and reported having "normal side effects after the second dose" including achy arm, low grade temperature, normal headache, achy joints. However, yesterday morning she woke up with a "weird" headache that she describes as pressure moving around from side to side and pressure in the back which was not like a normal headache for her. She states that she has taken Tylenol and it did not completely resolve the headache. She also reports that it improved since yesterday, but she does still have the headache today and she wants to know, at what point should she be concerned. The patient was stated that when she took Tylenol to help with her headache it did not help very much. She was calling about the Pfizer, verified Pfizer Covid Vaccine, she has received both doses. Caller states she received her second dose on Thursday 08Apr2021, and she felt like she had the normal, not that bad symptom. Stated that was on Friday and Saturday and done by Sunday. Caller stated yesterday morning, she started having weird headaches and she was not a person that gets headaches, she maybe takes Tylenol once a year. Clarified the headaches are random bursts of pressure on one side, then the other side and then the back of her head then on both sides, all day long. She had no issues in the night and when she woke up, it was back again but not as fierce. Caller asking was this potentially part of the Covid thing, were you think you are done with the symptoms and then another one comes along. Is this related? Stated it worked for her normal headache, but it did not work for her weird headache. She noticed with the first one, if she moves around a lot it dissipates, but if she treats it like it has pain, it stays. She does not take any medications. Caller wanted to know how long headaches typically lasted after receiving the Pfizer COVID-19 vaccine in the clinical trials and what was the best thing to take for this type of headache after receiving the Pfizer COVID-19 vaccine. The adverse events were not resulted in emergency room nor physician office. Therapeutic measures were taken as a result of normal headache/weird headaches, pressure moving around from side to side and pressure in the back which is not like a normal headache for her. The events were reported as non-serious. The outcome of achy arm, achy joints/joint achey, tired was resolved on 09Apr2021, normal headache/weird headaches, pressure moving around from side to side and pressure in the back, which was not like a normal headache for her, low grade temperature was resolved on 10Apr2021.
