sinus headaches; Her platelets are supposed to be 150,000 to 180,000, and hers are normally 120,000. Right now they are like 30,000.; Suspect ITP; This is a spontaneous report from a contactable consumer (patient).   A 68-year-old female patient received bnt162b2 (BNT162B2), dose 2 administered in Arm Left on 26Feb2021 (Batch/Lot Number: EL9267) at age of 67-year-old as 2ND DOSE, SINGLE for covid-19 immunisation.  Time the Vaccination Was Given Between 1100 and 1300. Vaccination Facility Type was Mass vaccination drive thru site. Medical history included she had a low platelet count before the vaccine, Seasonal allergies, Sinus headaches, diagnosed allergies, compromised immune status, respiratory illness, genetic/chromosomal abnormalities, endocrine abnormalities (including diabetes) and obesity. She doesn't remember what vaccines caused her to have a sore arm, maybe tetanus, but she doesn't remember. Her maternal grandmother had leukemia which is one of the possible causes. She never had anybody else in her family with ITP or anything like that. Concomitant medications included paracetamol (TYLENOL), ibuprofen, caffeine, paracetamol (EXCEDRIN), all taken for headache.  She had both doses of the Pfizer covid 19 vaccine. The patient had her first dose of the Covid-19 Vaccine (lot: EL9269) on 05Feb2021 in her right arm and her second dose in her left arm on 26Feb2021. One of the reasons she got them in 2 different arms was because she heard she might be less likely to have arm pain. She doesn't remember what vaccines caused her to have a sore arm, maybe tetanus, but she doesn't remember. It has been years since she had another vaccine. She had enough that she actually wrote in her journal on 28Feb2021 that she was getting unusual black and blue marks all over and they were bigger than usual. It is possible it was immediately as soon as she had the second dose. She wrote on 28Feb2021, but she knows that is not the first day she noticed it. It is getting better. she still gets new ones that seem random. She has 2 marks right now on her trunk. She has one on her stomach and one on her side. She is still getting them but not as frequent or as bad. Some she knew where they were from, and others she had no recollection of hitting herself. She went to the doctor and had a regular physical and bloodwork done, and she is in the process of being diagnosed. They suspect ITP (Immune Thrombocytopenia  Purpura). The AE require a visit to Physician Office. She gets seasonal allergies, and from time to time she gets sinus headaches. She thinks she might have had some headaches at that time. She assumed they were sinus headaches because it felt like they were. During the day she took 1 Excedrin and 1 Extra Strength Tylenol for the headaches. At night she sometimes took 2 Tylenol and sometimes Ibuprofen. She does remember having some headaches. Her headaches come and go. She had them she is thinking in February or March. She still has headaches. It is normal for her year round. She had quite a few more for a while, but now it is more normal like once a week. She takes the Excedrin, Extra Strength Tylenol, and Ibuprofen as needed. She tends to go with Excedrin and Tylenol for headaches during the day if she can. At night she tends to go with Tylenol unless she took it too close to bedtime to be able to take it at night. The Tylenol is 500mg. The Excedrin is a mixture of 250mg Acetaminophen, 250mg Aspirin, and 65mg caffeine. When she took the Ibuprofen she usually took 600mg. She did have bloodwork done. Her platelets are supposed to be 150,000 to 180,000, and hers are normally 120,000. Right now they are like 30,000. They said if she notices anything weird to go to the ER. She has had several platelet tests done. The first was on 04May2021, and her platelets were 30,000. The second was on 11May2021, and her platelets were 30,000. She had it done again on 17May2021, and her platelets were 25,000. Last week she had a bone marrow scan, and she will need a bone marrow biopsy. She did have a bone marrow biopsy done at a surgery center, but no treatment. It was to rule out other possible causes. The outcome of sinus headaches was recovering, of other events was unknown.
