incredible chest pressure; shortness of breath; anxiety; chest started hurting; pain across her breasts; concentration levels are off; but being that sick makes her so weary.; She goes to the bathroom 12 times a night to urinate; body aches; feet hurt/top of her feet hurt really super bad/legs hurt; pressing under her arm and she had pain really bad there; pain went around her back /whole back started hurting; This is a spontaneous report from a contactable consumer (patient). This 60-year-old female patient received BNT162b2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 1 via an unspecified route of administration administered in right arm on 27Apr2021 (Batch/Lot Number: ER8731) as single dose for COVID-19 immunisation. Medical history included ongoing congestive heart failure, diabetes, high cholesterol and high blood pressure. Concomitant medication(s) included aripiprazole (ABILIFY) taken for an unspecified indication, start and stop date were not reported; atorvastatin calcium (ATORVASTATIN CALCIUM) taken for an unspecified indication, start and stop date were not reported, noted as on of the 2 new heart medication; and another unspecified heart medication. No other vaccine within 4 weeks.  The patient received the first dose of the COVID-19 vaccine on 27Apr2021, then 2 days later on 29Apr2021 she developed side effects of body aches and couldn't get comfortable sitting, laying down, or standing, and her feet hurt, the top of her feet hurt really super bad and her legs hurt. She stated she was feeling "fair to partly cloudy" and "this is just beyond anything". She stated she literally didn't want to exist anymore the pain was that horrible, that when she was experiencing adverse effects she couldn't get comfortable in any way, nowhere to go, nothing to do, no warm bath, no hot warm or cool compresses, it was just her whole body. She said there was nothing that would help and she just didn't know if she could do that again. She only had relief through paracetamol (TYLENOL) and she took so much that she felt her liver was in jeopardy. She stated it was a really bad experience. The patient was also having incredible chest pressure and shortness of breath, onset date unspecified. She had a diagnosis of heart failure/a history of congestive heart failure, with the body aches she was having, she thought she was going into heart failure. She did call an ambulance twice (maybe 29Apr2021 then 01May2021; she didn't remember exactly which days) and the emergency medical technicians (EMT) took an EKG each time. The first time she called the ambulance the EMT's offered to take her to the hospital. Her EKG did look abnormal but it could have been attributed to her history of heart related issues or anxiety. The second time her chest started hurting it was hard to distinguish between pain and pressure. There was definitely pressure. There was also pain across her breasts (onset date unspecified) and underneath her arm (on 29Apr2021; initially she was pressing under her arm and she had pain really bad there), she was questioning her lymph nodes. Then the pain went around her back and then her whole back started hurting and her whole body was hurting, onset date 29Apr2021. She had never experienced anything like this before, as stated. She also reported that her concentration levels were off (onset date unspecified). She couldn't listen to music or do anything like that. She spoke with her doctor but being that sick made her so weary (onset date unspecified). The patient reported she didn't know if her symptoms were because of the COVID-19 vaccine or because of her new heart medication, but she said it's stupid to think her symptoms could be caused from her new pills. Her doctor wanted blood work on 27Apr2021 primarily because of all the medical diseases she had. She's guessing maybe blood work would give her an indication of why the vaccine made her feel the way it did. She went on 05May2021 to get bloodwork. She went to the bathroom 12 times a night to urinate (onset date unspecified) and she asked her doctor to put her on Lasix so she could just get the urine out. The doctor told her that her heart and her lungs sound good.  The patient asked if she should still get the second dose of the vaccine as she was worried that the symptoms could be worse after the second dose. She was supposed to return for her second COVID-19 vaccine on 14May2021, but she was not going (though she knew she needed to get the second dose), she did not want to get it.  The events body aches, feet hurting/legs hurting, pain underneath her arm, back pain, were ongoing but lessened in severity. As of the time of reporting, she had started to feel better, these events (body aches, feet hurting/legs hurting, pain underneath her arm, back pain) were resolving. The outcome of the other events was unknown.
