arm hurts; pain is in the left arm, also where she received her shot; This is a spontaneous report from a contactable consumer or other non-health care professional (patient herself). A 66-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Batch/Lot Number: EW0180), via an unspecified route of administration, in left arm on 11Jul2021 (at the age of 66-years-old) as dose 1, single for covid-19 immunization. The patients medical history included heart patient, this started in 1989 when she had her first heart attack on 04May1989, diabetic (for about 20 years at least), atrial fibrillation (A-fib) since 01May2019 when she had a perforated ulcer and had surgery and developed this, restless leg syndrome (she has had for 3 years), fibromyalgia (she has had 20 plus years), osteoarthritis (she has had 20 plus years), rheumatoid arthritis diagnosed Jun2019 and Covid in Jan2021. The patient had no family medical history relevant to adverse event. The patient's concomitant medication included insulin. No other products reported. The patient had no history of previous immunization with the Pfizer vaccine. No additional vaccines administered on same date of the Pfizer Suspect. Prior Vaccinations (within 4 weeks) no other vaccinations within four weeks prior to the first administration date of the suspect vaccine. No adverse events following prior vaccinations. The patient previously had a shingles vaccine and as best she can remember no reaction to those. The patient mentioned after the first dose on 11JUL2021 she experienced soreness of her arm and pain. Patient stated it was not as much soreness, it just hurts. She can hardly lift, and it has never stopped. It was continuous. She has tried Tylenol and everything and it makes no difference because it was the muscle. She was in medical centre in with heart related problems and it required she needed a vaccine. She had Covid in the first part of January which was really rough. She confirms that the hospitalization was prior to receiving her vaccine. She was in the hospital and decided she would go ahead and do it. The doctors suggested it would be a good idea with all of her health issues. She has many health issues. The doctor advised her that the overall risk of taking the vaccine certainly outweighs having Covid. The arm hurts started the first day of her vaccine. The second day has been worse and she has hardly been able to lift her arm with her right. She states the injection was in the left arm, pain is in the right. It seems to be she cannot raise her left arm without using her right arm. To pick up stuff and whatever, she cannot do much of anything where she had the injection. She clarifies statement as she previously mentioned different arms. She confirms the pain is in the left arm, also where she received her shot. She confirmed her left arm was hurting. She took Tylenol but it never phased it. She knows it was Extra Strength 500 mg Tylenol. They had been giving her 1000 mg in the hospital, so she took 4. She also took Oxycodone 7.5 mg, and it has not done anything either. She states it was the same thing as Percocet, but she does not have any information on this. She received the vaccine at 2 pm. She had been in the hospital a couple of weeks. She was there back in Mar2021 and inquired about it then to the doctor and they told her to take Johnson and Johnson, or actually, take Pfizer because Johnson and Johnson talked about blood clots which she was prone to. The Pfizer was chosen for her. Caller has no additional information regarding her statement on Johnson and Johnson but states she heard it causes blood clots. She was on a ton of medications and they have all changed since then. She has about 25 of 30 different diagnoses, but she cannot remember them all. The adverse event not required visit to emergency room and physician office. She was a patient in the hospital when she inquired about getting the vaccine. She had been in the hospital from 09Jul2021 to 11Jul2021 prior to receiving the vaccine. She asked if there anything she can do for herself or maybe get some sort of relief like heat or ice. Caller was advised Pfizer does not provide medical advice. Caller declined transfer or further transfer and states she will contact her physician and see how it feels in the morning. Caller confirms the pain is in the left arm, also where she received her shot. No relevant tests were done. Outcome of events was recovered.  Information on Lot/Batch number was available. Additional information has been requested.
