Clinical course: Dates when patient was in hospital for Probably had pericarditis was unspecified. Calling in regards to his last Pfizer Covid-19 booster that he received on 21Oct2022. Lot: GH9697. Decided he had to call. Tried to fill out a form as a result of the first booster and decided the heck with it because the form was too complicated, so he never reported anything. But, the second booster in October has set off and triggered some horrendous itching. After the first booster, he was itching just on his back and was given gaba and the itching phased off towards end of year. With the second booster, within 2 weeks, he had horrendous itching. Found out there were a couple people who said they itched as well. The itching is all over his body. The itching can be constant and then stop, and it can also flare up in little patches. It is more comprehensive itching this time. Itching moved to his chest, and more bodily itchy. After the first booster, itching was just his back. Now, itching is practically everywhere on his body. Explodes with itching throughout his body at times, but there is always a constant itch present. Itching will travel as well. Itching is so bad he has to implement certain interventions to make sure he doesn't scratch. Since the itching started, it has now reached the point of being terrible. Itching is at it's worst right now. The itching was bad from the beginning. He is at his frustration point right now. The itching is not subsiding like it did the first time. Took several months for the first time to settle down, but it did stop. Was prescribed gaba and then reduced the amount of gaba pills and went down to almost none and the itching started faded away. Itching was at a point where he could barely feel the itching, but came back within two weeks of the next booster. The itching is on more parents of his body now as well. All of his vaccines were Pfizer vaccines, and they were all given in his left arm. Did not receive any other vaccines that same day. Nothing that he is aware of that could be associated with this itching. Went in and had a complete review and the doctor couldn't find anything that could have excited this or done this or triggered this. His underlying feeling is it is either something brand new or the itching is  something he already had going on in his body that the vaccine triggered or set off. Has not been to the emergency room for the itching. Did see the allergist the first time it happened with the first booster.  Allergist said no, its not an allergic reaction and prescribed the gaba at first. Allergist thought it was a neurological issue. Just recently, he had a trip to the emergency room because he has an enlarged aorta and thought he was having an attack. Surgeon found there was no blockage and said he probably had pericarditis. The membrane around the heart may have been inflamed and presented itself as a heart attack. Caller did catch Covid about 2-4 weeks ago and went to the hospital and they gave him an antiviral pill. Because of the medication he was on, they didn't want to give him the antiviral that started with the P, so they gave him a different antiviral. Can not recall the name of either of the antivirals. With the suspected heart attack they started prepping him for surgery immediately and he was admitted. They ended up not having to do the surgery and found the suspected pericarditis instead which is a good thing. Just felt the itching was so intense this time. The sister of a friends of his was going crazy with the itching as well. She was also experiencing this significant itching. So, he thought is was time to make Pfizer aware. Friend mentioned that her sister at times feels like shooting herself because the itching is so bad. That's a hyperbole for sure, but it gets bad. He uses things like pressure, cold packs, and tries to keep himself from itching. Has to be careful because he once bruised himself from itching.  The information on the batch/lot number for BNT162b2, BNT162b2 omi ba.4-5 has been requested and will be submitted if and when received.
