He was going to look up his prescription because there is a specific dosage in each pump. Each pump was 20.25 mg, and he uses 2 pumps once daily, 40.5 mg once daily total. He says he had a question; he was having a side effect and he was not sure if it was related to the vaccine. He had the first one, he hadn't had the second one, but he had the first 04 Mar and he felt sick, he felt real weak the next day. He was fine after that, that Friday his right arm was sore and that was sore for a couple days but that subsided, it was fine and then a week later 11Mar, he was trembling, his whole-body trembles and he had hot flashes as well and he does not know if it was related to the vaccine, but he had not been able to stop shaking since last Thursday. He was trying to see if that was associated with product. He confirms he had the first dose 04 Mar and the next day 05 Mar he had weakness. His arm was sore a couple days. He says all of that was recovered completely now. He says the trembling began 11Mar. He says hadn't had a fever, he was trying to explain, it feels like if he was fighting off an infection or something, there was constant shaking as if he did have the chills, but he doesn't. He had hot flashes like he will get hot then he will get cold, but he doesn't run a fever at all, there was constant shaking. Caller was a 44-year-old male who received his first dose of the Pfizer BioNTech COVID-19 vaccine on 4MAR2021 and reports that his arm was sore for a couple of days after. He then states that the next day he began to experience "feeling real weak and tired" but states that passed. He also mentions that that Saturday, his arm was no longer sore. However, the following week on a Thursday, he reports he was trembling and "shaking like he had a chill" but reports not having a fever. He states that it had been "constant shaking" since last week that will "ease up some" but does not fully go away. He also reports hot flashes where he will get cold and then get "real hot" but again reports no fever. Caller states that the only medication he tooks was testosterone gel once a day in the morning and had been taking this for about a year.
