The patient received the Pfizer Covid 19 vaccine three weeks ago and experienced sleepiness, heart racing, fever, dizziness and her feet felt really heavy where it was hard for her to move her feet. The patient had high blood pressure. The patient stated that her first dose was scheduled at 8AM and she had to wait closer to 9 to receive it. The patient was so tired so she laid down for 30 minutes and got up and her heart was racing. The patient had no high blood pressure and eats right and takes medication. The patient felt dizzy and went to her friend's house in case and she had to lay down and didn't look good, pale with a red face. By 4pm she was in bed with a fever and her husband struggled to wake her up later and she had not taken anything. The patient felt clammy and burning up and had to hold water for her to drink. The next morning her bed was soaking wet from her fever and she was dragging her feet, her brain tells her feet to pick up but she cannot do it and she couldn't do hardly anything the next day. The patient was supposed to take the second shot this Friday, but she was concerned about the reaction with her heart. She knows people have a reaction to the second shot because the body says it recognizes this and fights it and to her this is an extreme reaction. The patient was afraid to get the second dose and wanted to speak with someone. No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
