He got the Pfizer shot twice, first shot was in mid-June and the second shot was around Sep2021. He ended up with some type of hives or raised bumps on his arms and front chest after both doses. These bumps are turning into hard skin cells, does not know how to explain them. He went to the dermatologist, and they took biopsies of the ones on his arms. He does not know if it was covid vaccine related but both times it happened within a couple of days of getting the shots. It first started as being itches/itching shortly after each dose and now his skin cells are all hardening up on his arm. He went to urgent care to ask for something to stop the itches and he was given a prescription for Triamcinolone Cream. After second shot the bumps/itching/hives came back with a vengeance. His skin was turning hard. It looks like he has cancer things growing all over him, they are white hard skin lesions which are in the proximity of where the hives/itching/ red pimple like things are. He stopped at a dermatologist, and they are dumbfounded as to what it was and are concerned about the lumps. He asked if there was any connection with the bumps and the covid shot and dermatologist states she had not seen that before. However, he talked to the pharmacist when he went to pick up the ointment and they told him that they have heard of this happening. He was now on a tapered dose of prednisone, and he would try different ointments, he thinks one was called clobetasol. He just took his last prednisone. He was talking to pharmacist and was told to report this. First dose: He did not have his first card with him at time of second vaccination. So, he received a card only for his second dose. First dose was in Jun2021 around noon to 1300. He does not know the exact date and does not have lot, ndc, or expiration date for the first dose. He was left-handed. Vaccination facility type was pharmacy. Vaccine was not administered at private facility. Additional vaccines administered on same date of the Pfizer suspect was none. He may have gone to ER after the first dose since he was opening up his bill and it said he was in the ER in June. Confirms he was not admitted. He only goes to ER for kidney stone or something else and he was not having a kidney stone in June. Physician office was yes, dermatologist and urgent care. The patient was not hospitalized. Prior vaccinations (within 4 weeks) were none. Adverse events following prior vaccinations was none. Family medical history relevant to adverse events was no. Relevant tests were none. Does he have to worry about these hard skin lesions, states he was probably not using the correct term by calling them lesions, but his skin was scaly and hard and growing up and down his arm and are now up to his shoulder.   Follow-up attempts are completed. No further information is expected.
