She describes it as her arm goes numb, it almost feels like her arm gets electrical shock in it. It's been there for over a year. The reported stated "I still feel my arm super tender. I know the pain is from that because I don't work with my hands or arms. I do have this sensation there and it bothers me every day. It's very painful." The reporter stated she got the vaccine and had never been that sick. The patient has had it for over a year now. Her arm goes to sleep and she has a lot of nerve problems now. She can't go to sleep her arm goes numb and constantly feels like she got poked in that one spot. It is always feels tender like she just got the shot that day. This is just concentrated in the arm area. She had lab work and other stuff done and she was told she has arthritis in her lower body area but her arm pain has been getting worse. States she got Covid. She couldn't sleep at night. Attempted clarification and caller states her arm was dead, like it was numb or asleep, felt dead. She couldn't tell she had an arm. It was tingling. States she doesn't remember if she told her doctor all of this, but she was scared. Caller also states she had pixelvision. Attempted clarification and caller confirms that the pixelvision was before getting the COVID Vaccine. She that the pixel vision when she had covid. Attempted clarification again and caller confirms she had covid before she got the COVID vaccine. She had covid in Jan2021. The pixelvision lingered on and off. She had a lot of inflammation when she had covid. She waited to get the vaccine. They were not giving them to everyone right away. She still has the sensation right where she got poked. It is very tender and hot. She feels like she is going crazy. Like there is a little hole or something super tender.  And her arm feel really weak on that side.  She can't sleep, the tingling feels like electricity going down to fingers. States she is not a conspiracy person. She got the vaccine and had never been that sick before. It wore her out. She is not an antivaxer. She is up to date on all her vaccines. She recently got her tetanus vaccine. She was scared and was waiting for the symptoms to wear off and they never did. When she does to sleep her arms go numb and start to tingle. She considered getting the second shot but wants to be cautious. There were no additional Vaccines Administered on Same Date of BNT162B2. There were no Prior Vaccinations within 4 weeks. She can't remember the date she went to her doctor but she did call her because of the sensation and feelings she was having in her arm. She wasn't thinking it was the vaccine. Her doctor did run some tests for numbness and checked her back. That is how she found arthritis in her lower back, she had an x-ray of her back done. Attempted clarification if caller was having numbness in her back as well and caller states no, just her arm.  Adds that when she goes to sleep it happens in both arms but the one she had the shot in feels like little waves of electricity it's not tingly she doesn't know what it is. She doesn't want to touch her phone because it makes her feel like a microwave. The patient underwent the following laboratory tests and procedures: lab: arthritis in her lower back; X-ray: Unknown results.
