A 59-year-old male patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection), dose 1 via an unspecified route of administration, administered in Arm Right at the age of 59-year-old on 07Aug2021 11:15 (Lot Number: FC3180; Expiration Date: Mar2022) as single dose for COVID-19 immunisation.  Medical history included ongoing low testosterone, trouble sleeping at night. Concomitant medications included testosterone taken for low testosterone from an unspecified start date and ongoing; clonazepam (KLONOPIN) taken for trouble sleeping at night/ help him sleep from an unspecified start date and ongoing.  The patient previously took steroids and experienced respiratory distress.  The caller states he just called the people he had gotten the shot from and they recommended him to call Pfizer. He states what happened was Saturday morning around 11am, he received the first vaccination shot from Pfizer. He states about midnight, he was watching TV, and then all of a sudden, at first it felt like gas then he ended up having a hard time being able to breathe, it was almost every 10 seconds , like a wave on 08Aug2021. He states it was more than gas, he had pain in the chest area on 08Aug2021. Any position he put himself into it didn't help. He states he took Phazyme, the max dose, and it didn't touch it, he didn't know what to do. He had considered going to the emergency room because his pressure went up (Aug2021) and at one point he was just thinking he had to go to the emergency room. He had seen a doctor and he said the emergency room is filled with Covid patients, and he doesn't need to expose himself so he stopped himself from going. He states it lasted for 3 hours, it was non-stop, but it finally subsided. He doesn't know exactly what happened but about 0330, he was finally able to drift off to sleep. It felt like he was having a heart attack (Aug2021). He states he's had a reaction before that was very similar when he had a steriod shot years ago, he told the doctor and the doctor told him that he should never take a steriod shot again because it gave him some kind of respiratory distress. He does not know what happened, he just needed to report this. The person that he spoke with said according to guidelines, only if he went to the emergency room is when they say not to get the second shot and he would have had he known COVID patient were not there. He states he did go to the urologist Monday, he thought he was coming down with a bladder infection within an hour of getting the shot on 07Aug2021, he felt pressure in his prostate on 07Aug2021, he started having spasms on 09Aug2021 morning about 5:00. He states the urologist said he's gone through a patient who was in pain and having pressure in the prostate and he did lots of labs and tests (Aug2021) and nothing showed up. The doctor said the best guess is its a side effect of the Covid shot, and there is nothing to do but time and it will wear off. Started feeling pressure down there: He states that Saturday morning, within the hour, he started feeling pressure down there, it subsided, then it would come and go. He states he woke up Monday (09Aug2021) morning about 5:00 and it started spasming and that's when he called the urologist and he was diagnosed with prostatitis and the doctor said it would go away with time. He doesn't have prostate problems. Prostatitis: diagnosed 09Aug2021, ongoing, persisting. He states it has subsided, not enough even to mention. Monday was the worst and then that afternoon he felt like he wasn't spasming. It may happen once or twice during the day but it subsides quickly. He states he doesn't even know, he is scared to take the second shot. It was asked if the call handler recommend taking the second shot. States it's probably not a good time right now to be transferred, he will call them later. He states he went to see doctor about another reason and he thought he had COVID, he was coming down with a sinus infection (Aug2021), and the doctor said go ahead and get him tested (Aug2021) with everything going on so they ruled him out and they gave him a Covid swab (Aug2021) and that came back negative and the doctor started telling him what was going on and the doctor scared him to the point where he said he was going to get the injection.The patient underwent lab tests and procedures which included blood pressure measurement: went up   in Aug2021, laboratory test: nothing showed up in Aug2021, investigation: they ruled him out in Aug2021, sars-cov-2 test: negative in Aug2021.  Therapeutic measures were taken as a result of events (Treatment: Over the counter Phazyme 250 mg, 12 gel capsules, took 2, box says only allowed to have 2 within a 24 hour period). Not visit to Emergency Room. AE(s) require a visit to Physician Office (on Monday, but he diagnosed with prostatitis, he went to the urologist).
