The patient had rash and itching on his chest, back, upper arms and legs for many months since receiving the Pfizer COVID-19 vaccine. He had itchiness over his chest, his back and his upper legs. The patient had serious rashes ever since. He had itching on his chest, back, and arms, that were not part of the rash. A week or so after his second COVID shot he began having chills, he was itchy and now he had serious rashes ever since then he went to his doctor and he also went to a dermatologist and they didn't know what it was or how to treat it. He had been ruled out for everything by dermatologist and regular doctor. He had been to so many doctors, they had given up. He has had all kinds of blood test, they even took a piece of the rash to biopsy it and they come back with nothing there, but here he was months later with chills and itching every day and a rash which responds to no sav that he used. He went to his dermatologist and his primary care doctor and had multiple blood test and biopsies and the doctors were unable to pinpoint any other condition. The patient had been seeing doctors since Feb2021 and no one had a solution for him. He had been in constant communication with his primary doctor and his doctor had no solution because all of the patient's tests had come back normal. The patient went to his regular doctor he was unable to give him all kinds of blood test and was unable to come up with anything, he had been to two different Dermatologist one did biopsy and could find nothing and his regular dermatologist gave him a 0.1 percent Cortisone (Unspecified Medication) which did not work. The patient wanted to know if it was a side effect of the vaccine and if anyone else had reported these effects and if there was any treatment or solution for it.
