Clinical information: Reporter mentions that her husband has to report that he had a serious reaction to the second booster shot from Pfizer. Has mentioned this to many different doctors and has had problems since Oct2021 when he had the booster. 48 hours after, almost exactly, he was walking with his wife, jogged maybe 100 yards, a slow jog, which he had been doing for many years. It was like someone strapped a rope around his chest and couldn't breathe, squeezing horribly. Draped himself over a barrier of the trail rail to keep from falling. Eventually, got his breath back, which took about 5 or 10 minutes and walked back to the house. Met with the doctor, who made appointment for stress test, which he failed and was well documented. Did a heart cath and he had no blockage. They were seeing that he had AFIB and tachy on bradycardia on the treadmill. There was no implementation other than that incident to even indicate that he had any problems. They did the heart cath, which showed there was a problem. Doctor was going to do heart ablation 15Feb2022 and he was on beta blocker Metoprolol. Clarified that he was put on that because of the stress test and had not been on it before. Went off the beta blocker and was supposed to be off it for 5 days. Went off that 12Feb2022 and 13Feb2022, the next day, he didn't take it and had stroke 13Feb2022. Survived that and they attributed it to the fact that it must have been clot. He did not have any neurological damage, thank goodness. Was in the hospital for that, for one day and they put him on the blood thinner, Eliquis, which they sent him home with and he is still taking now. Clarified that he was admitted to hospital admitted in hospital 13Feb2022 and went home 14Feb2022. Stroke started at 9:30am and he got to the hospital that afternoon. Went to the emergency room and was then sent to Hospital that afternoon. In the mean time, he has been struggling with all this stuff going on in his body. Developed floater in his right eye after the stroke: Saw that doctor again, who sent him to see an ophthalmologist. This was within a short period of time after the stroke. Was walking and doing the same things he had been doing, as he was told to do. Was not debilitated.  When the ophthalmologist looked at his right eye, he said it looked like someone stuck something in his eye. They did surgery with laser to correct the hole that materialized in the retina. That was not painful, just a little painful. Went home and has been ok. Was just another manifestation of all this. Was amazing to be so healthy and have all these things happen to him. They put him on a heart monitor for 30 days. The result what they found out his heart rate dropped to 30 and would some times go up to 167, which was the highest. Was from not running or training or anything. Then, they put a pacemaker in him, which was about 2 month ago and now, he has a pacemaker. His heart rate drops to 60 all the time with no symptoms, so this is kind of frightening. To be sitting here and to take his blood pressure, it is sometimes very normal but now has Afib. When he went in for a check up, at 6 weeks, they said he had been in Afib 5 times before. They told him was 36% daily and then they put him on another medicine. 15Apr2022 was when they put the pacemaker in. The other medication they put him on, in addition to Eliquis was Sotalol and he is taking that now, also. From a person who would almost refuse to take aspirin for a headache, he is now taking 6 different pills and 4 of which, he has been taking since the booster. Unfortunate all of this has happened to him. Almost exactly 48 hours after that booster, on that Monday, all this happened on the trail rail the following Wednesday. Had the previous 3 Pfizer shots that Feb2021. Was about 6 months from then to to the booster. His world came crashing down when he found out he had cancer. Then ended up in the emergency room and they didn't let him go home. Clarified that patient was diagnosed with prostate cancer after receiving booster shot.
