Anatomical Location of dose 2 was reported as arm Left, shoulder. He actually had Covid in Mar2020 and believes it was a near experience, near hospitalization experience. After taking the first dosage, he had symptoms like fever and chills. He just took the second dose last Thursday and was feeling a little more fever and chills, things he thought were natural. And asked whether it was normal to feel these symptoms. Event Details: Fever and chills: They occurred in almost the same time frame with both the first and second shots. It was within 12 hours. With the first shot, it lasted about 12-16 hours. With the second shot, it lasted a little longer, about 24 hours. He took Tylenol for both occurrences. Actually, before the second dose, he had gotten an EKG on his heart because he wanted to make sure he was healthy. When he got the shot, it felt like the first shot, like his body was getting all of these symptoms again, which was fine. It was unexpected a little with the second shot. He had joint pain, muscle pain and aches, fever, chills and headaches. It was the same thing with the second dose. It was the same time frame as the fever and the chills. He always got them about 12 hours after the shot was administered. This was why on the second dose he went earlier in the day, so he could get the symptoms earlier and into the night and until the morning. Then, he would be good to go the next day. Outcome: With the second dose, he does not know if this caused it, the shot but, he read up on it and saw that it was a rare side effect. He had insomnia for 2 days. It started on Sunday, or not it was Saturday, 2 days after the shot. States that it could also be due to anxiety. He has had anxiety after having Covid in 2020. His main concern was the insomnia. It was really weird. He does not know if it was anxiety or the shot. He does not really want to speculate at this time. It was all really emotional stuff and uncertainty as it was. insomnia, he can't sleep because his arms go kind of numb and his chest feels tingly and he gets a sensation like butterflies. Below the chest and in the stomach area, in the gut area, it goes into his arms and is like tingly. It was almost like circulation cuts off. When going into a deeper sleep, then he wakes up. It started yesterday, last night, it was Saturday evening, more like Saturday evening around early morning, Sunday. He would say it was probably about 3:00 or 4:00 in the morning. At the same time, the doctor had actually prescribed before the shot, some anxiety medication. He was anxious with the first dose. He took the medicine today, for the first time. Which was odd and that the medication did not help that feeling. He was prescribed 2 of them and he has only taken one, the Propranolol 10mg was prescribed to take regularly as needed when he does not get sleep and has really bad anxiety. He was also prescribed Escitalopram 10mg, to take regular, one daily. He has not taken it yet. He really has been weighing this shot out. He was not feeling this was as bad as he is now. Before he got the shot, his anxiety was kind of under control and he was able to sleep perfectly fine. NDC, LOT, EXP of Propranolol and Escitalopram unknown. These are both in prescription pharmacy bottles.  No follow-up attempts are possible. No further information is expected.
