Received call from consumer regarding the Pfizer COVID vaccine. She is a (Withheld) woman and will be 72 in (dob withheld). She received second vaccine on Monday. These are what she wanted to say. With the first one, the only symptom was soreness in arm for a day and a half. She later stated she had a coldness that was in her veins after the first dose as well. With the second one, like the first one, she had this coldness and chilling effect in her body. It did not last long. Now in second one, it is almost like she could feel the same chillness go through her body hours after she got the injection. Almost kind of like when you eat ice cream and it goes down cold, except it is in your veins and goes down. It went into the left elbow, which is the same arm that she had it in. There was no prescriber. The next day after receiving the first dose, she could only raise left arm half up because her muscle was sore. By the third day, it was much better and by 4th day, she had no problem. It got her muscle pretty good and inflamed it and nothing more unusual than a flu and shingles shot. She had not had the shingles shot, but she knows it is a big needle and her arm would be sore. She had the flu shot this last year 2020. She did have arm soreness with that in her left arm. She did not have a manufacturer, lot or expiration for the flu shot. After second dose, she felt coldness and it subsided and went away and two days later on Wednesday, she got real chilled at night and is still having chills. Everyday since, she has gotten a headache. She took 2 Tylenol because she has a stent in her heart and they prefer no ibuprofen, because the medication she is on is already thinning her blood. The stent was in 2017, which was prior to getting vaccine. The headache comes and goes but is not any more intense, just irritating. She was basically fine and this started Wednesday. Then she started having chills again last night kind of like when you have the flu. She has not had any fever. She just had a headache and now has nausea. She woke up while she was sleeping and thought she did not feel well. She wanted to know if it was unusual to be fine and then 3rd day out get symptoms. She was under the impression that you should not be having symptoms this far out 48-72 hours and wanted to know if was normal to have them 3 days out.
