A 54-year-old male patient received bnt162b2 (Pfizer-BioNTech Covid-19 Vaccine, Solution for injection, /Lot number was not reported, Expiry date: unknown, at the age of 54 years), dose 1 via an unspecified route of administration on 20Mar2021 as dose 1, single for covid-19 immunisation. Medical history included diabetes mellitus and car accident (he has never experienced neck pain like this, even after car accident he was in many years ago). The concomitant medications were not reported. The patient experienced pain in the back of his head and neck and reported that his head was locked and could not turn it either way. He described it as having a crick in the neck. He would like to know if this could be from the vaccine. He also reported that he had headaches since the vaccination, felt really sleepy and tiredness, and flu like symptoms. He developed neck pain on 21Mar2021. On Monday, 22Mar2021, he could not move his head. He was told that the Pfizer has joint type pain. He did not have pain anywhere else, no joint pain anywhere but his neck. He could not turn his head. He went to his primary care physician again. He was still experiencing neck pain, that he hadn't done anything to cause the neck pain, and that he could not do much. The neck pain was weird, it went from the back of his skull down to between his shoulders. When he turns, he felt the muscles tightening up in his shoulders. He could open his mouth only so far and he could not open his mouth wide. He had pain in his jaw back to the back of his head. Monday night he got scared because it felt like his throat was closing. He became very tired and sleepy the same day that he received the Covid-19 vaccine, 20Mar2021. The sleepiness began almost immediately after receiving the Covid-19 vaccine, before leaving the parking lot. He had headaches galore since Saturday night, 20Mar2021. The neck pain came in hard, and it was keeping his head locked up. He did not sleep funny, did not even use a pillow. Terrible pain could not take it. Mentioned he was kind of confused when providing dates for this report. When he tried to open his mouth wide, it hurt his jaw by his ears. His throat felt like it was swelling. Monday night, the throat swelling was not as bad Tuesday, 23Mar2021, that it was like it was alleviated. It seemed like at night the throat swelling acted different. He felt the throat swelling when he layed down and was experiencing the throat swelling slightly now. He was super tired and out of energy or something. He still felt a little drained at time of call on 24Mar2021 and that he tried to keep active. On Saturday, 20Mar2021, he had a headache pretty good Saturday night. On Sunday, 21Mar2021 the headache was kind of bad. He thinks the headache was from neck pain, that the headache was in the side of his temples and head. When he bended over, he felt a lot of pain in his neck, and it was hard to hold his head up. The outcome of the events pain in the back of his head and neck, headaches and could not open mouth wide was not recovered, for events really sleepy, tiredness and throat felt like it was closing up was recovering and for rest of the events was unknown.
