Patient clarified he has not required any physician's office visit, emergency room visit, or hospitalization relative to these events. For the first week after he was administered the Pfizer Covid-19 Vaccine he had no problem. He works out every day, cycles 50 miles daily, is in good health, had no problems. Because he has had 2 weeks of that so far. He also reported now because of lying in bed eating comfort food. But it's not a huge pain. The reason he got the Pfizer Covid-19 Vaccine was because he couldn't work out at his gym unless he had the 2 shots of Pfizer Covid-19 Vaccine. Patient verified that there has been no testing/ investigations/ treatment or medical interventions performed relative to these events. Administered at health office, which he described as a very high quality place. Second dose was scheduled for 08Dec2021; which he believes was 3 weeks after first dose administered but can't verify that for sure.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
