She said her joints hurt so bad compared to when she had the covid virus. Last night, she noticed some red blotches on her ankle but nothing on injection site and took some Advil and compressions - she said some side effects are subsiding now. She knew these side effects could probably related to the vaccine and that she wanted to know if she could get the 2nd dose. Told her that a certain percentage of the clinical trial participants also reported what she was experiencing right now after their first dose. Advised her to seek her HCP's guidance on whether it was safe for her to get the 2nd dose of the vaccine. Stated that she was just starting to feel better in Dec2021. She thought that she might have had some side effects from the infusion she received for Covid19. The infusion was called Regen-Cov (Casirivimab and imdevimab). She received the infusion on 20Oct2021; she did not have the Lot/NDC/Expiry to provide. Stated that she was calling to report her side effects after getting her Comirnaty vaccine and to ask if she should get the 2nd dose of the vaccine. It started with a sore arm on Friday at 5pm. Then she had chills all night long. Then into Saturday the joint pain set in, and it progressed to the point where she could hardly walk because her ankles and her knees hurt so bad. Stated that this was her first day that she could get out of bed. She had a rash on her left side on Saturday, but it went away over night. Then yesterday she woke up with ankle pain, and a rash on her ankle and both her feet swelled up. Clarified that it was the top of her feet by the ankle joint that swelled up. Stated that she also has rash spots all over her body, which had been there all along; mentioned they were on her leg and hip. The rash spots didn't  itch and they didn't look like hives. The joint pain in her ankles was pretty bad; it was like someone glued her ankles and she couldn't bend them. Clarified that the joint pain was in both of her ankles, but the right one was worse. Saturday night was the worst with the ankle pain and all night long she couldn't move because of the pain. Yesterday she took Ibuprofen and put on compression socks and laid down and kept her feet up. She was told to take Tylenol if she got a fever, but she never got a fever. Stated that this morning the pain in her ankles was much better. Stated that she did have weird stuff all over, including on her knees. Clarified that she was talking about the rash, or the redness.
