Bleeding/felt blood on her arm /blood was coming from the top of the band aid; This is a spontaneous report from a contactable consumer reporting for self. This 81-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot# EL3248) via unspecified route of administration on 14Jan2021 02:00 PM at right arm at single dose for COVID-19 vaccination, clopidogrel (manufacturer: Aurobindo, lot# QR7520022-A, expiry date: Apr2022) oral from Dec2020 at 75 mg once a day for TIA (Transient ischaemic attack). Medical history included TIA from Aug2019. She had her first TIA Aug2019, and then had her second a couple months ago, it was not as severe, the buildings moved and she walked like she was drunk, but had only one other thing than walking funny and buildings moving, she can't remember what that was. Pain, blood cholesterol abnormal.  Pain in both of her arms, she said her left arm hurt more than her right arm from time to time, and when the left started hurting she took all the pills, but she didn't take Hydrocodone though it is prescribed, she didn't take that unless she was in a lot more pain than usual. She said her doctors said different things about her arm pain, one said she had a torn rotator cuff, another said arthritis, someone else said it was something in her neck but it was a big word that she didn't know, she just knew she had pain. Concomitant medications included acetylsalicylic acid (BABY ASPIRIN, manufacturer: Bayer, UPC number: 349483 48150) from Aug2019 for TIA; carbamazepine from Jan2021 for pain in both of her arms; metoprolol succinate, had been taking it a couple years; zolpidem; hydrocodone for pain (she only takes if she is dying of pain, clarified to being in a lot of pain); atorvastatin for cholesterol. The patient reported that she had COVID-19 and experienced side effect. She said it happened after the 15 minutes observation when she left to drive home on 14Jan2021. She said 5 minutes into her drive she felt blood on her arm and put her hand in her shirt, and wiped it, saw blood. She said the bleeding was weird so she pulled over to look at her arm, and blood was coming from the top of the band aid where normally it would seep down from the bottom. She used five baby wipe, and wiped a lot of blood, until finally she thought it stopped bleeding. She was not light headed or in pain, it was a 45 minute drive and she got home and was still bleeding so she took her shirt off and put a towel around it to stop the bleeding and it finally stopped. She said she didn't think to report it until her doctor said to when she told him, he had said maybe the girl who gave her the shot hit a vein, but she should tell them. She said maybe she did hit a vein, because she had never had problems when getting a shot or more than a spot of blood in the past. She said one thing that may be important was that she had a couple of TIAs, many series (unable to clarify) her doctor friend assessed that with three MRIs and MRAs. She said she just refilled one of her medications, Clopidogrel, and was reading the instructions for it and it says it can cause excessive bleeding. She said that she was not bleeding so she didn't worry about it, that maybe that caused excessive bleeding.  She had not had a second dose, but she didn't want to go through this again with the bleeding, though if it was just a vein or air that may not happen. She said she was very healthy, no underlying conditions at all, never had a problem before, her arm was not painful, she was not light headed. She said the baby wipe she had on her arm after the car ride was full of blood, and she still couldn't get the band aid off, so she wrapped her arm towel kept sopping up blood until finally it quit. She put another band aid over the bloody band aid, and it quit and she was fine. She had no injection site pain, no tiredness, no headache. Lab data included she had MRIs and MRAs, but there was no bleeding. The action taken for clopidogrel was unknown. The outcome of event was recovered.
