he felt drowsiness.; it hurts to turn his head and he cannot drive safely; muscle pain went over to the other shoulder and basically spread out all over his upper body; he's been having muscle pains; This is a spontaneous report from a contactable patient. A 79-years-old male patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection, lot number: EL8982 and Expiration date not reported), via intramuscular route of administration in the left arm on 28Jan2021 07:30 as single dose for COVID-19 immunization. Medical history and concomitant medications were not reported. Patient was not allergic to anything. It was reported that patient was generally in good health in 79. He knows there may be some adverse effects. Last Thursday (on 28Jan2021) he got his first dose of the Pfizer covid vaccine and he's been having muscle pains. The only thing that has happened to him was a lot of muscle pain, quite a bit. Through the day he started to feel the muscle pain and through the night he felt some stuff (referring to the muscle pain), very lightly enough to be a nuisance. States from the waste up he felt drowsiness. The first night he slept some but not much since he could not get in a position where he could sleep very much. The next morning the muscle pain was much more severe, more pronounced on his left-side, which is the side he had the shot, particularly in several areas like right underneath his armpit and between his arm and elbow. By the end of 2nd day, the pain had spread to the right hand and the day after that, it was concentrated on the left arm on the injection site. The next morning the muscle pain went over to the other shoulder and basically spread out all over his upper body. It has since worsened by then. He broke down last night and he took two Advil, and he got a really good night sleep. This morning he got up and the muscle pain gradually came back but not quite a s bad, states maybe the Advil was slowly wearing off. States it was a funny sensation, a lot of them. Patient feels it on the bottom of the side of his rib cage and neck. He was asking how long the muscle pain will go on. He hates to combine anything he will experience from the second dose with what he was currently experiencing. Patients understanding was that the second dose will worse. Patient ask can he take the 2nd dose on his opposite arm (right), he do not want to feel pain on the same side again. He has a card that states when he was supposed to get his second dose. States it hurts, it hurts to turn his head and he cannot drive safely. States his wife got her vaccine two days before him. He puts his glasses on to read the con-tact details from his hcp card. When querying outcome of drowsiness, he reports it occurred a few times off and on and it comes and goes, it does not stay around.
