On January 21 I received my first dose of Moderna vaccine on my left arm. After the vaccine I had a red lump that was hot and a bruise that only lasted 2 days. Everything was fine until the January 28th when I developed a large red lump during the day while at work that was severely itchy and hot. When I got home from work I had a low grade fever. I made an appointment with my primary care for the next day which was Friday the 29th. My doctor told me she believes I had cellulitis. I was given an antibiotic 2x a day for 7 days. She drew a purple circle around the area and told me that if it goes outside the marked area or I feel any new symptoms, to go to the emergency room. Saturday morning on the 30th  i woke up to my entire arm red and hot. I felt like I had a huge sunburn. I couldn?t put my sweatshirt on because it was so hot. The emergency room doctor told me I was fine and to keep taking the antibiotics that were given to me yesterday from my primary care doctor. After the emergency room I went to work and started to feel dizzy and nauseous. My hands became sweaty but the rest of my body was cold. I started having a butterfly feeling in my chest. My Apple Watch alerted me that my heart rate was over 100 bpm. That night before bed I had another low grade fever. On Sunday the 31st I noticed the red area was gone but instead it was a dark purple. I felt okay Sunday besides a rapid pulse. Monday February 1st I woke up out of a dead sleep sweating, butterfly feeling in my chest and dizzy. I tried to take my pulse while laying down but it was so fast I couldn?t keep up with it. I put my Apple Watch on which alerted me immediately that my pulse was 152 bpm. I slowly got up but then I passed out falling off of my bed. I couldn?t get any words out because my heart was beating so fast that I couldn?t breathe. I was sweating horribly and had a hard time walking. Had absolutely no strength in my left hand, my arm was purple/red, cold and numb. My arm felt like someone punched me repeatedly and gave me a dead arm. I called my primary doctors office and they were able to get me in that afternoon. All morning my pulse was spiking and then drastically dropping. About an hour and a half before I went to the doctor everything was fine. I was able to talk but still struggled with breathing while talking. The doctor ordered an EKG which came back clear. My pulse and blood pressure was also fine. The doctor told me she believed all of the symptoms I had were from the medication I take at night (doxazosin-to relax my muscles and help with sleep.) She also told me she believed some of it was my mental health issues taking over. She told me the cellulitis looked fine and sent me home. Later that day I felt exhausted and when I woke up from a nap, I had a fever of 100.5. Took Tylenol and it dropped to 99.5 but wouldn?t go any lower. February 2nd  I woke up to a large red ring outside of the purple marker, numb finger tips and butterfly feeling in my chest. All day I received alerts that my pulse was falling and spiking. I sent my primary doctor an email and she told me she didn?t think it was cellulitis anymore, maybe a hematoma but she wasn?t sure. Since January 28th I still struggle everyday with the butterfly feeling in my chest, blurry vision, low grade temps, alerts of pulse, dizziness and breathing difficulties. My arm is always hot, my finger tips are numb and sometimes the strength in my hand is gone. The top of my arm is always a dark purple with red blotches and other times my entire arm is red and hot. When my pulse is very fast, I have a hard time talking, remembering what I was going to say and focusing. I?ve had multiple coworkers ask me if I?m okay because I?ll randomly stop talking and stare off and then I?m alerted that my pulse has either spiked or dropped drastically after spiking. My pulse is never consistent. It is always ranging from 57-155bpm. I realized at first I may have what they call ?COVID arm? but my symptoms haven?t gotten any better. No answers have been given to me or a diagnosis. The first diagnosis that they thought was cellulitis. Then it was ?in my head and behavioral.? Then it was a hematoma. Now it?s an ?I don?t know.? I have tried Benadryl for the itching, ice packs for the days that I?m swollen, Tylenol for the fevers and pain but I never have any relief.
