30 to 40 bumps on her left breast; 30 to 40 little red bumps just on that one breast; little, tiny bright red bumps on her breast; rash; Itching; Red lines almost connecting to every single dot or bump; This is a spontaneous report from a contactable consumer (patient). A 65-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE; Lot Number: EL3302), intramuscular in right arm, on 29Jan2021 (at the age of 65 years), as dose 1, single, for COVID-19 immunization; atorvastatin calcium (unknown manufacturer), via an unspecified route of administration, on an unspecified date, at an unspecified dose and frequency, for plugged carotid arteries; lorazepam (Strength: 0.5 mg), via an unspecified route of administration, on an unspecified date, at 0.5 mg, twice daily, to go to sleep (or in order to get through the day); valaciclovir, via an unspecified route of administration, on an unspecified date, at an unspecified dose and frequency, for herpes; and potassium chloride (Strength: 10 mEq/mL), oral, on an unspecified date, at 90 mL, every 2 weeks, and then at 8 tablespoons, every 2 weeks, for deadly hypokalemia. The patient's medical history included immune deficiency, high blood sugar (not diabetes), left arm is broken, deadly hypokalemia (deathly cramping), herpes, plugged carotid arteries (carotid artery is 50% stuck), go to sleep, and thyroid. The patient explained that she has 40 diagnosed medical conditions. The patient also had agent orange exposure in the 1970's which continues to wreak havoc in her system. The patient was immune deficient, but they do not know if she has lupus or rheumatoid arthritis. The patient explained that she doesn't have enough veins to know. She only has one vein left, and it takes 6 months' worth of blood test to determine what she has. She can only have 1 blood test every 6 to 9 months unless it is an emergency. If she has to have blood taken and doesn't have a vein, she has to drive an hour away to a place that takes it out of her neck, and she can't drive that far anyway. The patient has lung issues and cough issues. She gets bronchitis really easily. Right now, the wind hasn't stopped in 3 days and she isn't having any issues, so she hasn't had to take medication (benzonatate). If she is coughing and sounds like a cartoon character, she takes some. The patient's concomitant medications included thyroid (ARMOUR THYROID) for thyroid, benzonatate for lung issues, acetylsalicylic acid (BABY ASPIRIN) for plugged carotid arteries, and unspecified vitamins and minerals. The patient previously received pneumococcal vaccine for immunization (pneumonia shot). Because of her deadly hypokalemia, every 2 weeks she takes a compounded incredibly high dose of 90 mL a day of liquid potassium chloride liquid. It's 10 mEq/mL and she can take up to 90 mL, sometimes she gets away with 4 tablespoons. She takes 4 tablespoons in the morning and 4 in the evening with 1 cup of water, so she doesn't die of deathly cramping. She is surprised she hasn't died yet. The patient has these medicine cups that she fills to the top. The cups say 1 fluid ounce and she fill the cups twice in the morning and twice in the evening. She believes it is 8 tablespoons. She has tried to take less but its deadly. The pharmacy boils it pure with nothing but cinnamon, and then places it in empty green vials. The patient takes lorazepam just because of her life, she doesn't have a happy life. Since she is totally immune deficient, she has a high regimen of vitamins and minerals because she has deathly hypokalemia. The patient has received her first dose of the Pfizer vaccine, her second dose is scheduled this upcoming Saturday. The day after (30Jan2021), the patient developed 30 to 40 bumps on her left breast and red lines connecting to each one. It lasted for about 2 weeks. As of today, it is very light. Although, she received the vaccine in her right arm. The doctor told the patient it could be her supplements which she takes for her history of deadly hypokalemia, high doses of potassium chloride, lorazepam, atorvastatin, and valaciclovir along with other vitamins and minerals. The patient also took a mammogram 18 days before. She is immunodeficient so effects from the mammogram might have lasted longer. The patient would like to know if her side effects could be a reaction to the vaccine. It was further reported that the patient was looking online and explained that nobody seems to have the same reaction to the injection as she has had. The patient explained it was going to be 3 weeks on Friday that she received her vaccine. The patient going to be receiving her next injection this upcoming Saturday.  On 30Jan2021 (also reported as about 2-3 days after receiving the vaccine; it could have been before, she doesn't know), the patient was itching and noticed her left breast had a rash. She saw there was about 30 to 40 little red bumps just on that one breast. It was very itchy. It still itches now. Over two weeks or about the day before the 2-week mark, she saw red lines almost connecting to every single dot or bump. It's bizarre. The patient's partner thought it was dog that scratched her, but the lines are connecting to every single dot (bump). Today, it does look better. The lines are getting lighter and lighter. The patient explained that she took the vaccine on Friday and the thinks that already by Sunday, she actually started feeling the itch. It was a pretty horrific itch and she looked down and saw she had little, tiny bright red bumps on her breast. It wasn't like pustules that are opened up and gooey. It almost looked like measles, where she has these tiny, bright red bumps. The lines started going through them, almost like the lines were connecting the bumps. The patient again explained that her partner thought it looked like the dog scratched her with his nails. However, she has a tiny puppy and his nails had to be 1 inch apart to make that kind of scratch and they are not. For some reason, after a certain length of time, there were red lines that connected the dots. The lines were long, it was like a 3-4-inch stripes. The lines are much lighter now. She thinks that within 4 days, it would be gone. It will probably be gone the same day she receives her shot.  However, the patient was not seeing anything about anyone else having this kind of reaction. Somebody said they had little red bumps on their feet, but nothing has been reported like she has. The patient a little nervous about receiving the vaccine. However, she does have lots of things happening in her life and there has been bad weather for days which could be affecting her and making her nervous. The patient did take a mammogram and she asked her doctor how long she needs to wait to have the vaccine after getting the mammogram. The doctor told her she was fine to have it done within 3 days before the vaccine. She confirms she took the mammogram 18 days before inoculation. The patient happened to have a doctor's appointment via telephone that following Monday. She noticed the rash on Sunday and had the telephonic doctor's appointment on Monday. She told him about the rash. He asked about when she got the mammogram because he didn't know if it was because of that. The doctor believed it wasn't supposed to be done within the week of having the vaccine, but she had it 18 days before the vaccine. The doctor also didn't know if it was because she is on a number of herbals and supplements because she releases vitamins and minerals all day long through her urine. She supplements with vitamins and minerals that she takes morning and evening. Although she looks great for her age, she has issues. The patient makes the comment they never did studies for people who have immune deficiencies. The patient underwent laboratory tests and procedures which included mammogram (18 days before; 2021) and blood test (November, unspecified year); unknown results. The patient would like to know how long she must wait to take a dose of another COVID-19 vaccine if she is unable to get the second dose of the Pfizer COVID-19 vaccine. The patient would like to know if people still get the vaccine if they experience the same side effect. The action taken in response to the events for atorvastatin calcium, lorazepam, valaciclovir, and potassium chloride was unknown. The patient had not recovered from "Itching". The patient was recovering from the other events.  Pfizer is a marketing authorization holder of atorvastatin calcium in the country of incidence. This may be a duplicate report if another marketing authorization holder of atorvastatin calcium has submitted the same report to the regulatory authorities.  No follow-up attempts are possible. No further information is expected.
