nurse was putting it in the wrong spot because it hurt so bad; pain in left arm; This is a spontaneous report received from a contactable consumer (patient). A 78-year-old female patient received second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, solution for injection, Batch/Lot Number: EM9809; Expiration Date: 30Jun2021), via an unspecified route of administration on Left arm on 07Feb2021 14:10 as 0.3 mL, single for COVID-19 immunisation. Medical history included rotator cuff surgery from 2013; Back problems, had brain surgery when she was 39 and she still has ongoing disability from that. Patient stated that born with the disability in her right hand and a cyst, they just didn't find the cyst until she was 39 and that's when she had the surgery. Family history was reported as none. The patient's concomitant medication was unspecified allergy shots, once a week and ongoing. The patient historical vaccine included first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; Lot number: EL1283, Expiry date: 30Apr2021) on 17Jan2021 for COVID-19 immunisation. It was reported that, the patient has gotten both shots and she didn't have any problems with the medication, but she had a problem with the 2nd shot, so she was calling for advice. States that she got her 2nd shot on Sunday, and the nurse either stuck it into a nerve or into the muscle because she felt like her arm was going to fall off before the nurse even pushed in the medicine; states that she wanted to scream. Now she was still having pain in that arm, but it's not exactly where the shot was, it's running down her arm and it's not constant, it comes and goes. States that she did have rotator cuff surgery in 2013, and that's kind of what the pain feels like now. This is in her left arm, which was the only arm that she can really use, because she had brain surgery when she was 39 and she still has a disability from that. Clarifies that she was born with the disability with her right hand and a cyst, they just didn't find the cyst until she was 39 and that's when she had the surgery. States that it scares her because she only has the use of one arm already. She had no problem with the medication in the vaccine either time. States that the second time she got the vaccine, she knew that the nurse was putting it in the wrong spot because it hurt so bad, like so bad that she wanted to slap her. States that the pain is nowhere near like it was on Monday, but she didn't know who to call. She gives herself allergy shots, so she knows how to give herself injections. States that the vaccine was perfect, she had no side effects from that. The first shot, she didn't even know that she had gotten a shot. States that yesterday her arm didn't feel as bad as it does today. It's more aggravating. Again, states that the pain was like what she had after her rotator cuff surgery. States that she hasn't felt that pain since her surgery, then on Sunday when she got the shot the pain has kind of started back up. States that it has definitely improved. On Monday and Tuesday, she would feel a little twinge of pain about every 3-4 hours, but today it's every 10-15 minutes. The patient not visited emergency room and not visited physician office. The outcome of the event pain in left arm was recovering and was unknown for another event.
