Initially, my only symptom was a burning sensation up and down my right arm. After the 15 minute observation period, I left the clinic and drove to my office.   As I drove to my office I started experiencing minor "numbness" in my left arm, left shoulder, and left side of my chest. Within a few minutes of arriving in my office, I had to leave and walk to a meeting.  As I was outside walking to the meeting I started feeling chest pain, fatigue, a pounding in my chest, and breathing felt "heavy." I arrived a little out of sort to my meeting and was advised to go back to the clinic.   While sitting at the meeting my symptoms lessened.   When walking back to my office the symptoms became stronger. I was asked if I was okay to drive and I was; I quite literally felt 100% conscious and able.   Upon returning to the clinic, I asked to speak with a doctor about my side effects. The doctor checked my vitals and asked how I was feeling. By this point I had commenced feeling a numbness in my extremities, walking felt heavy--like I had to consciously think about picking up my feet--walking felt laborious. Thus, even though all I wanted to do at the moment was lie down?as my fatigue had significantly increased?I answered the doctor?s questions and fully planned on returning to work after she checked me. My vitals were within normal range and so after the doctor told me severe allergic reactions to lookout for and reasons I?d need to go to an ER, she advised me to go home and rest. She worried that I didn?t have anyone that could drive me home, or another adult in the home to observe me for the next few days.   I assured her I would figure out a plan. Leaving the clinic and walking to my car I was short of breath, and still experiencing the other symptoms. As I drove back to my office from the clinic, I started feeling a swelling on the left side of my throat. As I touched my throat I could tell it was swollen and felt the glands swollen. I touched the right side of my throat and it felt normal. I communicated these symptoms to my leadership at work and was dismissed for the day. My boss offered to drive me home but I felt bad asking this of her since I live an hour away. Even though I was experiencing all these symptoms I felt completely conscious and able.  Of course, I wasn?t at my prime but I felt strong/aware enough to sit in a car and steer/push the pedals/react. It?s important to note I?m a single mother.  My son only has me.  My getting sick/being hospitalized/etc., are not options.  I willed myself to get it together and overcome these symptoms.? Of course, at the time I wasn?t aware I was having an allergic reaction to the vaccine.  I simply thought this was my immune system?s response to some component of the vaccine and that it would be over soon.   Another symptom that I experienced intermittently throughout the day was pain on the left side of my uterus.  I do not experience cramping/menstrual pains, and thus this was out of the norm for me. Regardless, I made it home to my son that night and rested. Resting decreased the symptoms. The only new symptom I experienced that night was a burning sensation at the heel of my hand when I leaned on my desk, and rested weight on my hand. The swelling of the left side of my throat and glands went away within 2 hours of onset.  This was quite abnormal for me.  Sunday morning I woke up with the same feeling of a weight on my chest, chest pain, shortness of breath when doing any activity?even blow-drying my hair. I contacted a cardiologist and he suggested I go to an ER and get a full evaluation and documentation. Which I did. When I initially arrived at the ER I was out of breath from simply walking from my car to the ER. I had to catch my breath continuously to answer all the questions asked during the registration process. I was out of breath and feeling chest pains as I sat on the bed at the ER. I opened up a breathing exercise video and focused on my breathing, and regaining control of my body. My breathing returned to normal within 2 hours of sitting on the bed at the ER. The ?final? EKG at the ER looked great according to the doctor and I was discharged after 4 hours. I was given specific instructions of signs to look for/reasons to return to the ER.  To this day I continue to experience minor chest pain and shortness of breath/feeling of fatigue, which increases when walking around and doing normal activities.     My plan is to work with a doctor to figure out which component of the vaccine I?m allergic to.  I will also continue to get evaluated if these symptoms don?t go away.  I?m really hoping they do though.
