Clinical narrative: On Sept 26, 2021, I received my 2nd dose of the Pfizer COVID-19 vaccine at a Pharmacy.  I noticed after my shot that I had more bleeding than after my first dose.  I specifically remember the pharmacist removing the needle from my arm, and then wiping away oozing blood several times before applying a bandage.  The next day after I removed the bandage, I noticed that the bandage pad was saturated with blood in contrast to when I received my first dose that made only a small dot of blood on the bandage pad.  A few days after my second dose, I developed an approximately 1-inch diameter sized bruise at the injection site compared to after my first dose when I had no bruising at all on my arm.  A week after my second dose, during the week of Oct 3, I noticed sensations of "muscle burning" over my body, especially in my arms and legs.  The muscle burning sensations were not painful, but were noticeable, and to clarify, they did not feel like body aches.  Near the end of the week and into the week of Oct 10, I noticed sensations of flurries and slight pressure in my chest, especially when sitting and relaxing.  These sensations were not painful, but they were unique and not like anything I had ever felt before.  On Oct 15, I started having heart palpitations that occurred every few minutes.  The palpitations lasted continually until Oct 17.  On Oct 19, while walking at work, at approximately 1:00 PM, I started having deep chest pain.  While having the pain, I started sweating heavily and became clammy and light-headed.  I also started feeling extreme fatigue.  While walking, the chest pain became more intense.  Overall, the pain in my chest lasted for approximately 30 minutes.  The pain eventually turned into chest achiness and feelings of mild pressure in my chest.  At approximately 3:00 PM, I arrived at the ER.  Labs were ordered and my first troponin read was 0.38 ng/mL.   Due to my elevated troponin, I was flagged as critical and moved into an ER room.  Later that day I was admitted to the hospital where I was put on heparin and aspirin.  My WBC (white blood count), preliminary abs neut, neutrophils %, lymphocytes %, absolute neutrophils, and IG were high and out of ref range on Oct 19.  My WBC, preliminary abs neut, absolute neutrophils, lymphocytes, and monocytes continued to be out of ref range on Oct 20.  My troponin eventually peaked to approximately 1.14 ng/mL.  On Oct 20, my attending cardiologist, performed a coronary angiogram ? all coronary arteries were found to be completely normal.  My last troponin read prior to my angiogram was 0.64 ng/mL.  On Oct 21, I had an echocardiogram ? my heart was found to be completely normal.  At approximately 2:00 PM, on Oct 21, I was released from the hospital.  I do not take medications, drugs, or herbals of any kind.  I exercise regularly, eat a balanced diet, only have occasional glasses of wine and no other types of alcohol, have never smoked, and have never taken any kind of illicit drugs.    As I write this summary, I continue to have sensations of flurries and slight pressure in my chest.  I believe I experienced an adverse response to the Pfizer COVID-19 vaccine and wanted to share my experience.
