I had a very strong immune reaction with the first COVID-19 vaccine that I received. I had an immediate cardiac arrhythmia response, but I had weeks of achiness and inflammation after. With the second dose, the same thing happened, and I had months of a great inflammatory response where I had inflammation in most if not all of my joints. I saw multiple doctors and tried natural methods as well as pharmaceutical methods. I finally got all of this under control and felt comfortable going forward with my first booster. Almost immediately, I felt that same strange warm tingly sensation, but it felt stronger, and I was experiencing a stronger irregular heartbeat and pressure on my chest. They insisted that I be monitored for some time until that calmed down. I don't remember exactly what my heartrate and blood pressure were. I came home after close to an hour of monitoring. I continued to have more cardiac events. There were a few points that I came close to calling 911, but I am hesitant to do that. I just kept doing what I know how to do to manage irregular heartbeat. I did contact my primary care physician at some point and tried to get in touch with my cardiologist. I was also experiencing headache and extreme fatigue. It got more and more difficult, and I felt like someone was sitting on my chest and it just kept increasing over time. I was trying to be seen by a cardiologist but was having trouble getting in to see them. I tried really hard to turn things around. After around two months, around December or January, I starting to get intermittent pain under my left arm that was shooting into my breast. I didn't connect that to this at all, but it was happening around the same time. In March, I started to try to exercise again, and I couldn't do more than a maximum of 10 minutes of very mild exercise without feeling like I was going to drop. The pain that was shooting into my breast was increasing so in April, I tried to get into physical therapy again to attempt to build up my stamina again. I finally got an appointment set up with my cardiologist in May. I had a mammogram, ultrasound and a biopsy in April. In the ultrasound they discovered an enlarged lymph node in the left axilla and after they biopsy, I was diagnosed with Non-Hodgkin's Lymphoma. When I saw my cardiologist in May, he scheduled an echocardiogram for June. I tried to talk to him about this and express my concerns about the cardiac events I was experiencing. His response was to warn me against having any more vaccines. He stated that he had not had any and urged me to report this issue. During this time, I also started to experience Peripheral Neuropathy and I've had some blood pooling in my feet. We have not yet determined what is causing those two issues. I had the scheduled echocardiogram, and it did show that there have been changes. I expected some changes as I got older, but I was kind of surprised at the number of changes in such a short time as I have been in pretty good health before this, and I had an echocardiogram a few years prior to this one. I wanted to talk with my cardiologist about my questions and concerns over the results of my echocardiogram but was unable to really communicate with him about that. He basically said that yes there are changes, but nothing to raise any red flags at this point. Looking back, after doing my research and speaking with doctors, my symptoms seem to be that of cardiac myopathy, but I have no predisposition to any sort of heart issue. My cardiologist did express that the CDC is researching development of Non-Hodgkin's Lymphoma being caused by inflammatory reactions to COVID-19 vaccines. I do not think that my vaccine caused my diagnosis, but I do feel that there is some kind of connection there. In addition to all of this, I have been experiencing brain fog to the point where I thought I might be having a stroke. I have also experienced numbness and swelling on the right side of my tongue, and it will also turn white. None of the doctors I have been seeing have been able to diagnose that issue.
