After the first dose, my arm hurts/aching left arm; I can't hold my left arm up holding onto the wheel because of the ache\It is right in the muscle where they gave me the shot; This is a spontaneous report from a contactable consumer or other non HCP (Patient herself). A 62-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Batch/Lot Number: ER8727) via an unspecified route of administration, administered in Arm Left on 27Mar2021 (at the age of 62-year-old) as 1st dose, single dose for COVID-19 immunization. The patient medical history included ongoing asthma Diagnosed about 10 years ago, nasal polyps, auto immune disorder, really sensitive she gets sick very easily, Samter's triad (Genetic disease. Diagnosed 12 years ago) and hoshimottos. The patient's concomitant medication included dupilumab (DUPIXENT) 300; self injection every 2 weeks2x/week taken for asthma and nasal polyps. The patient previously took ciprofloxacin hydrochloride (CIPRO) (From: Unspecified To: Unspecified) cipro disabled the caller. Cipro took the patient's livelihood away. The patient took it 9 years ago (3rd of November. Lot, NDC, and expiration date unknown for the product). The patient didn't thought she would walk again. The patient previously took shingles shot. She mentioned that her shingles shot was much worse than this (Shingles shot- lot, NDC, and expiration date unknown). It took the caller 2 years to go get the second dose of the shingles shot because her arm hurt so bad but then it cleared up. The patient stated that, she has talked to her doctor about this, and they do not have any answers so she thought that she have got to clear this out. She got her Pfizer second dose she got the Pfizer vaccine and after the first dose her arm hurts (on 28Mar2021) and that was okay because she expected that. Now she got her second dose and her arm ache again but her arm has got breaking (not clear) and it has been a month now and she was literally concerned, and it was right in there where they gave her the shot. Sometimes it was worse than normal like it aches to the point where like during driving her car she can't hold her left arm upholding onto the wheel because of the ache and it was right in the muscle where they gave me the shot (in 2021). It was so bad and sometimes it hurts without me touching or moving or anything and other times it was like okay but then she move it and it literally stops me and she didn't know who else to call but Pfizer because she don't know what to thought and she don't know what to do. Other than that, she has no ill effects. She hasn't been shake, she haven't been weak, none of that. She has been doing good. Her doctor still thought maybe they hit a nerve but she just does not know. The patient was calling about the covid vaccine. The patient had her first one in 27Mar2021 and the only thing she had was an aching arm in the left arm (On 28Mar2021). On 17Apr2021 the caller got her second covid shot. The caller had never bled during a shot, but she bled probably 3-4 drops of blood at the injection site. After the shot, the caller's arm hurt, and it has been 1 month and 10 days and her arm was still aching. She asked this normal or natural. She asked has anyone else complained about this. The patient's doctor said they could have hit the nerve and he could see the scab where the vaccine was given, this was two weeks ago. The patient's arm doesn't always hurt but when it hurts, it really freaking hurts. The pain radiates down into the front of the arm. Now the pain goes into the shoulder and into the collar bone area. The pain was so bad the caller couldn't even keep that arm on the steering wheel while she was driving. The pain that the caller was experiencing was the same ache as when she got the shot. It was slowly getting better but when it hurts it really freaking hurts. The patient's doctor doesn't seem to be bothered by this happening to the patient. First Dose: aching arm it hurt for 3 days max. The patient thought it started early morning the day after she received the covid vaccine. Second dose: left arm hurt- this started the day after the patient received the covid vaccine, she thought. It got worse until about a week and a half ago. Now the caller can hold on to the steering wheel with the left arm. The pain starts slowly creeping in like a contraction and intensifies and then soothes out and goes away. The caller's left arm always hurts when she lifts her arm, no matter which direction. It was painful reaching out and up. Usually, this pain was not triggered by anything. Second dose: Received 17Apr2021, lot EW0161, NDC and expiration date unknown. The caller received both doses of the covid vaccine in her left arm. The patient doctor said it may take time to heal, but she was a little scared because she doesn't know what is going on. The outcome of the event was unknown.   Information on batch/lot number was obtained. Further information has been requested.
