12/29/2020- Received the Moderna Vaccine - no pain or problems until 01/04/2021 01/04/2021- Before bedtime my injection site from the Moderna Vaccine became itchy.  01/05/2020- Woke up to a swollen arm (about 3 times the size of my right arm) and the start of a rash (the size of a softball) Was in significant pain and unable to lift my arm. I called the nurse hotline where I received the vaccine. I was told to go to the ER immediately. The ER doctor informed me that they had been seeing this and that their personal vaccine location swelled up as well but went away a few days later. ER doctor gave me Benadryl cream (I can not ingest Benadryl due to an opposite reaction, I become extremely anxious.) The ER doctor informed me that the Benadryl cream wouldn't cause the same reaction. I was sent home with the cream and a wrap. Upon arriving home my rash grew exponentially over the following days. The site became hot (even after icing it) It remained itchy and painful.  01/11/2021- Went to primary care doctor. The rash and swelling had decreased although you could still see the ring of the rash. At this point, my hand was becoming numb after doing daily activities including typing. My palm and thumb area started to turn purplish/blueish when I would type for less than 20 seconds. The doctor told me they would start to reach out to other providers and figure out how to best move forward. In the meantime, there wasn't much to do besides wait and see what happens.  01/13/2021- Woke up throughout the night due to continued pain at the injection site. Called the primary care doctor who wasn't in the office, waited for a call back from their nurse but due delayed call back and  increased pain and numbness went to urgent care (which is under the same practice as primary care). The urgent care doctor performed tests regarding pinched nerve shoulder (as they believed I had a pinched nerve in my shoulder) and ordered an x-ray. The x-ray showed tissue damage but nothing else. I was not experiencing shoulder pain, although during one of the shoulder tests I found more discomfort in my left should (injection arm) than my right arm. Therefore, the primary care doctor thought I was experiencing a pinched nerve in my shoulder.  01/14/2021 - Primary care doctor called and informed me they had spoken with the infectious disease doctor in the area who informed them that they have been seeing a similar reaction amongst other people. (7 days after inject, swelling and rash) The infectious disease doctor reported they hadn't seen numbness. The primary care doctor advised me to wait 2 weeks to see how symptoms change before performing additional tests. The primary care doctor also advised me after speaking with the infectious disease doctor to not take the second shot.  01/16/2021- still experiencing issues with daily functioning. Still experiencing numbness in hand and arm. Still experiencing redness around the injection site (although much better still flairs up at moments)   Side note: 01/03/2021 - Went cross country skiing, did fall backwards but did NOT fall on arm.  Also confusion remains if  I was supposed to report this or if the primary care doctor/ER doctor reported this, therefore, urgent care doctor told me to report this reaction.
