A 74-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot number: EN6205), via an unspecified route of administration, administered in the left arm on 03Mar2021 (at the age of 74 years old) at a single dose for COVID-19 immunization. Medical history included lumbar spine infusion (operations on spinal cord) from an unknown date and unknown if ongoing. There were no concomitant medications. It was reported that the patient needed the call handler to speak slowly, she doesn't feel that well. She had the first dose of BNT162B2 last 03Mar2021 and the second dose will be on 23Mar2021. She said something was happening to her arm but it was not where the needle went in, that is not where it is. It hurt there at where the needle went in, in the beginning but now it hurts down toward the elbow and it penetrates through the epidermis, endodermis and the muscle and feels like it's at the bone. She hopes it was not a blood clot. She has been looking at the website and they say people could have blood clots and she does not know if this was a blood clot, she can't hardly lift her arm, it was the left side that the shot was in because her right side is partially paralyzed due to effect of lumbar spine infusion and so when she tried to get up sometimes she can hardly lift that arm and so she didn't know what to do if she should call the primary care doctor to see if she has a clot but she read it and it says to call this number if you are having compactions and she been on hold over and hour and a half. It was hurting and the feeling like she couldn't hardly raise the arm or get any kind of strength in it. She knew in Europe they have had few people who have had blood clots, and she thought could that be a sign of a blood, like blood not moving through her veins like it is supposed to. It is not moving it has not made it to her heart yet. She says it is associated with the product, this is the only thing she has had in her arm she knows it is the product. She said her birthday just passed. She turned 75 years old but when the issue started in her arm she was 74 years old. It did not start the first week, the first week it was just sore around where the shot went in but then last week it started happening where it was hurting down her arm and she was getting close to the second shot which she doubts she will have but it is the 23rd which is next week. She used to be 5'2" but the operations on her spinal cord, she guesses she might be 4''10 now. She does not know because she can't hold her head up straight because the doctor that fused it, she indented it instead of it being more out and because of that her head is forward and down. It was also reported that she hasn't been to the doctor she only goes to pain management for him to check out her body and everything and renew prescriptions. The outcome of the events was unknown.
