The patient clinical course was reported as follows: About 12 hours later almost to the hour, he had symptoms including: fever, real bad headache, chills, and the fever ran somewhere 100 or a little over he guesses. This lasted most of that morning on Wednesday on the 24Feb2021. He took his temperature with an oral digital thermometer. He reports his temperature usually ranges 97.7-97.6 somewhere around there. And he couldn't get warm. He had a mattress heater turned up and he felt weak and since he's by himself he has to get up to get water and he put his heavy robe on then he got back in bed. He never went to sleep, he couldn't fall asleep, his arm really hurt where he got the shot. There was a little ache with the first one but this one here really, really was bothering him. When he first got the second shot, he hates needles, it was a little sore and then when this started it really started to hurt and it was warm. That went on to the morning, then it started letting up a bit. His daughter came by and made him chicken soup and he felt a little better, still weakfish. His fever went down kind of far and he laid down the rest of the day. Towards dinner time or so he felt warm but didn't have fever, he went the opposite from being chilled to being warm but his temperature was around 98. Then later on he was taking some pain medicine, called his doctor and asked what he should take for the headache. Take whatever he has there is what he was told. Acetaminophen-aspirin/pain reliever/caffeine/pain reliever he thought he said it was 250 a pill. 250mg of aspirin 2 at one time by mouth. 65 mg of caffeine. Took 2 about every 5-6 hours. It says Headache relief, caller states he is just about blind, acetaminophen-aspirin/pain reliever/caffeine/pain reliever he thought he said it was 250 a pill. 250mg of aspirin 2 at one time by mouth. 65 mg of caffeine. Took 2 about every 5-6 hours. It got rid of whatever he had. Patient stated he needs to change the thingy on his CCTV. Clarified he uses a CCTV magnifying system, it's a camera system with the 24 inch monitor. He felt better then he fell asleep around 10 that night and he woke up around 4:00AM on the 25Feb2021. He reports whatever fever he had, he was soaked but he felt really ok then from then on. He finally got up around 7-730 AM and he's feeling ok now. If he had a fever it broke. He reported it seems to be improved on the 25Feb2021. He was feeling pretty good he started making coffee so he didn't feel bad and he hasn't had anything since. He reports his arm is not bothering him unless he pokes it. It's the same thing with the flu shot, if he pushes on it in a certain place he knows he got the shot.
