A 73-years-old female patient received bnt162b2 (BNT162B2, formulation: solution for injection, lot number: not reported), via an unspecified route of administration, administered in Arm Left on 24Mar2021 16:00 (at the age of 73 years) as dose 1, single for covid-19 immunization.

The patient's concomitant medications were not reported. She declined to provide concomitant products; but mentioned she does take medications for chronic pain in her neck and back because of some herniated discs and she has a couple of implants, but they are not pain implants. She had 2 ablations done on the nerves on her neck, the right part of her neck about 2 weeks prior to getting Pfizer COVID-19 Vaccine injection and her neck hurts worse now. She has not taken any pain medications for these events, she has just taken Tylenol and used Cortisone 10 cream she is putting on it for the itching. Her mother in 70s had myasthenia gravis; father had pancreatic cancer and died of it at age 81 years but that's the only problems they really had. The patient previously took flagyl [metronidazole benzoate] and experienced drug hypersensitivity, shingrix for immunization, pneumococcal vaccine for immunization. On 25Mar2021, the patient experienced big lump swelled up on her arm (big lump the size of a hen egg at the injection site), it as becoming red, irritated and itched like fire, left arm hurt, was sore, temperature, neck pain, couple of little red marks and scratches on her left arm where the lump is. She explained the day after the injection, she had a terrible reaction, where a big lump swelled up on her arm. She further described it as becoming red, irritated and itched like fire. She had a lot of itching up until yesterday. She added the lump had gone down and was small, but you can still feel it. She felt fine that day, but her left arm hurt, was sore starting on 25Mar2021. She couldn't even lift her arm and there was a big lump the size of a hen egg at the injection site, the injection site of left arm is itching, whole left arm was real red and fiery and left arm hurts really bad. She might had a temperature the first day, on 24Mar2021 after the Pfizer COVID-19 Vaccine was administered, but she had temperature starting 25Mar2021, which was at least 100 degrees, but no higher than 100 degrees. She took Tylenol for temperature and temperature only lasted a day, before abated. She was putting ice and 70% rubbing alcohol on her left arm. She can't lay on her left side because of the pain. She normally sleeps on right side and stated that it's a good thing because it hurts so bad that she can't even lay on her left side due to the pain in her arm. She turned over onto the left side and had to turn back really quick because it hurt. She had a couple of little red marks and scratches on her left arm on the sides where the lump is and its probably from where she scratches through the night. Ever since this has happened she puts ice on her arm and heating pad on her neck. She was scheduled to get the next shot on the 21Apr2021 at 14:30 at Walgreens and was asking whether she should get the next one, or not.  The lump's getting smaller; lump was much better. The Pfizer COVID-19 Vaccine injection had even made her neck hurt where she had that done up her arm into her neck, it's really sore-She later mentioned she is not sure if it was from the Pfizer COVID-19 Vaccine. Her neck hadn't hurt before the Pfizer COVID-19 Vaccine after the ablations, but after the Pfizer COVID-19 Vaccine her whole neck where she had those injections in her neck it started hurting. She had Covid back in December, it was a bad case but pulse ox never went under 91 so she was ok there; and she had a fever for several days and her temperature usually runs about 97 so anything over 100 was pretty bad for her. She was terrified of fevers, she hates that because it makes her feel so bad and she was wondering if she needs to take the next shot that she was supposed to take on 21Apr2021 since she has already had Covid. She had a really bad reaction and she did not want that to happen again if she did not need to have the shot. Patient stated she might have too many COVID antibodies since she was positive for COVID already before she got the Pfizer COVID-19 Vaccine. Also she was tired and wants to sleep a lot. She had longhauler's syndrome since she had COVID in Dec2020. Her doctor described it as still kind of like a hangover from COVID and sometimes it lasts 6 months. She went out to smell the Christmas trees must have gotten sick then because within a few days she couldn't smell anything. Clinical outcome of the event scratch, temperature, left arm hurt, was sore, it as becoming "red, irritated and itched" like fire (erythema) was reported as unknown, big lump swelled on her arm was reported as recovering and not recovered for rest of the events.
