On Wednesday 24Mar2021, mid afternoon, he had purple splotches all over his body, in arms and legs, like discoloration, his head felt like it had been dipped in cement and he couldn't think. States he felt cloudy, dizzy and woozy, nauseous, had a headache and feeling awful. States this occurred like 48 hours after the shot. He contacted a life long friend who is a doctor and works in a covid ward and he told him he was having a reaction and to take some Benadryl and Advil or Tylenol, and the friend told the patient to lay down and rest. He still didn't feel great but splotches went away and head felt a little bit clearer and he didn't feel like he was in slow motion or dizzy anymore by Wednesday evening, so he went to bed. On Thursday, the patient went into work but didn't feel great, not feeling 100%, and about noon on Thursday 25Mar2021, the symptoms started coming back, the purple splotches, his head felt just as bad, he had a headache, slow motion and not himself.

Patient states he was admitted into the ER and the ER staff said he was having more than likely an allergic reaction to the vaccine. They gave him steroids and an IV but he is not sure what it is and he was given, he thinks, Prednisone over the next couple days to help with side effects, he believes it was Prednisone, he knows it was a steroid. States he is not a fan of it and he doesn't like it at all. Patient states that he thought it was a pretty standard reaction and was not worried about it. Patient states he still gets headaches and maybe it's something else that is unrelated. States he stopped feeling tired and sluggish maybe the 29Mar2021, a week afterwards. Patient states that he has recovered with lasting effects as he's been getting migraines since then, states maybe it's unrelated but didn't happen a whole lot before. He has severe headaches and nothing he takes seems to help, has to turn lights off and works from home and patient reports that he had one yesterday. Patient states the purple splotches went away after he went to the ER and got on the medicine, the steroids.
