Caller definitely wants to report his side effects after the vaccine. The agent believes the caller received both doses of the COVID vaccine. He was got CRPS and said that he had terrifying pain in his body where he received a parasympathetic nerve injection somewhere in his lumbar region, it varies between L2 and L5. The caller clarifies the injection was a mixture of lidocaine and a steroid, but the caller was not sure what the steroid was. The agent explains the caller said quite a lot but basically was asking what Pfizer did to him and why was his life ruined. He had a heart condition and was told he needed the vaccine. The caller wanted to report the severe pain he experienced. The USMI agent did inform him of statistics from the clinical trial and post-trial results. He states he still had the pain that is normally addressed by the nerve injections and he just had a total loss and it put him back to zero. The caller clarifies he experience severe pain each time he had the shot, which he had the shot twice. The pain lasted about 3-4 days each time. He clarifies his entire body was in pain, specifically where he has neural issues on the left side. He verifies he had Complex Regional Pain Syndrome (CRPS) and he gets a nerve injection every 6 weeks. He had his most recent injection last Monday. For 3 days, the injection was slightly debilitating. He received his COVID-19 vaccine in his left arm both times. It started with a sharp pain, generally in the spot where he received his nerve injection and the pain dissipated after about 2-3 days. He received one of these nerve injections a day or two before getting his first COVID-19 vaccine and the COVID-19 vaccine totally wiped out all the relief he normally gets from receiving those nerve injections. He states he still had the pain that was normally addressed by the nerve injections and he just had a total loss and it put him back to zero. As far as injection pain, he experienced pain for 3 or 4 days in the left arm directly from the injection. The benefit he normally gets from the nerve injections that last for 6 weeks was totally wiped away. He was engulfed with pain from that and also was engulfed with pain from the COVID-19 vaccine. Caller states he will be discussing these nerve injections with his HCP next Monday. He clarifies he had no name, ndc, lot and expiry date for the nerve injections he received. He stated it was basically like a certain cocktail. He switched doctors and his new doctor was aware of his situation. He had not really been diagnosed but he has seasonal allergies. He clarifies he takes Flonase and a prescription strength, Cetirizine. He mentioned the Flonase he had been taking 3-4 years, on and off. The Cetirizine he started taking about a month ago. He confirmed he took it once daily, but he was not sure of the dose. He believeed it was the lowest dose, like 10mg or something. He mentioned he was using like a saline pump thing to clean his nasal passages, but he has gone back and forth as far as it being effective. As he got older, his problem got a little worse. Caller confirms he does not have any of these products available to provide ndc/upc, lot and expiry dates from. He had the nerve injection prior to the vaccine. The caller states the pain from the injection was unfortunately a very straight line, it was undeniable. He states he also had a tetanus shot 2 weeks prior to the COVID-19 vaccine and there was no interaction he can recollect in between this Tetanus shot and the COVID-19 vaccine. Caller states maybe when he was younger, he had a little soreness but nothing worth mentioning. Caller clarifies maybe like with polio or all of his other childhood immunization, he remembers getting some of these immunizations, but he doesn't remember having an adverse reaction at all. Caller verifies he has no ndc, lot or expiry date for any of these immunizations. The outcome for all events was unknown.  Information about lot/batch number has been requested.
