A 72-year-old female patient received second dose of bnt162b2 (Pfizer's Covid 19 vaccine, Solution for injection, Batch/lot number: EN6205, Expiration date: unknown), via an unspecified route on an 11Mar2021 (Thursday) at 10:00 (age at vaccination: 72-year-old) as a single dose for covid-19 immunization. Medical history included arthritis and skin cancer. Nothing was been diagnosed. She was sure she did better with her blood sugar and her high blood pressure, but she was not on any medications for that, she just need to be careful about her diet. She doesnt know, she hasnt had it tested in a while, she stated it's possible it's on the high side like most people are and because she doesnt get enough exercise but it's nothing that she has to take medications for so. Concomitant medications included L-Carnitine because patient was vegetarian although she eats fish, she is not a vegan; Vitamin C; Multivitamin; Calcium; Joint Supplement; curcuma longa (Turmeric); tocopherol (Vitamin E); Vitamin D and Niacinamide as is supposed to help with skin cancer but she doesnt know if they really know that. Historical vaccine included first dose of bnt162b2 (Pfizer's Covid 19 vaccine, Solution for injection, Batch/lot number: EL9266), as a single dose for covid-19 immunization. On 11Mar2021, after finishing the second dose of Pfizer patient felt fine. She waited 15 minutes because it was a drive through and then she went for a walk a little later, she walked about a mile and went home, nothing. In the evening, she felt a little tired, so she decided to go to bed early and when she woke up it was night and she hurt all over. She just woke up and she couldn't think what to do and just started drinking a little bit of water. She stayed in bed, but it was very painful all over, her kidneys hurt she don't know why, she thinks it's her kidneys, her lower back whatever 2 organs liver or kidney, something internal anyways. She continued the night, but she was unable to sleep because no matter what position she was in something hurt so she would wake up about every half hour and in the morning, this was Friday morning (12Mar2021), she had to get up to feed her animals, she really didn't want to, but she was very weak. She went out to her kitchen and when she was trying to open a can of cat food, she got very dizzy and hot cool clammy sweats and she kind of slid down to the floor. She didn't fall, didn't lose consciousness but she stayed on the floor because it was so nice and cool for about 5 minutes or so and then she decided that she need to get up and get back to bed so she did that and she stayed in bed all of Friday and she also had a migraine because she is prone to that but she didn't want to take any medicines because she didn't want to there to be any chemical interactions with whatever was going on. So, she just stayed in bed all day Friday and it was really miserable. She never had problems breathing, she didn't have any shortness of breath, nothing like that but her entire inside hurts and many parts of her body. She is 72 so she have arthritis (Medical history) and she also have aches and pains but they are not related to that but this was definitely a reaction because she have not had anything like that in, she have not been sick in years and she kept thinking to herself, she live alone but it's not an emergency she don't need to go to the hospital, this is a reaction, a possible reaction and nobody died from this so if wait it will go away. She was pretty sure she had a fever, but she didn't take temperature, she really didn't do anything but go back to bed. This is Sunday, she stayed not in bed all day yesterday but a very limited activity, also she didn't eat anything all day Friday except for water and she just had a bite of cheese and couple of blueberries because she didn't want to get completely weak and then Saturday she started again, she had a little bit of soup and that kind of thing. It was more extreme reaction than she expected but she thought she will give that information. On an unknown date, she didn't want to do the web thing because she didn't have the energy to sit on the website and type. Patient did not receive any treatment for the events, not even her regular vitamins, water. The patient underwent lab test and procedure which included body temperature as unknown. The clinical outcome of events: she felt a little tired; unable to sleep would wake up about every half hour; couldn't think what to do; weak; dizzy; hot cool clammy sweats; stayed in bed all of Friday; she didn't eat anything all day Friday except for water was recovering; fever got better now; headache went away and pain (it was very painful all over, her lower back whatever 2 organs liver or kidney/ it was really miserable, entire inside hurts) went away.  No follow-up attempts are possible. No further information is expected.
