I received the first dose of the Moderna COVID vaccine on Wednesday, 8/18/21.  I began to experience the extremely sore arm about 6 hours after the injection.  The next evening, Thursday, 8/19, my arm was still extremely sore and it was beginning to itch at the injection site.  The next evening, Friday 8/20, my arm was still extremely sore and I had developed a very small itchy rash.  I used a topical steroid cream on the rash through the weekend (8/21-8/22) and it cleared up.  The soreness in my arm had subsidized by the end of the weekend as well.  I woke up at 2:30 am on Monday, 8/23, not feeling well.  I was achy all over, had abdominal pain and felt nauseous.  I stayed home from work and slept all day, I was exhausted and had no energy.  My left armpit had been hurting all day so I checked it and realized the lymph node was very swollen?about the size of an egg.  By that evening, I noticed the area around my left collarbone was also swollen and tender.  The next morning, Tuesday, 8/24, I woke up with very sore and swollen glands in my neck.  The glands in my left armpit and collarbone were still swollen and sore.  I went to work and continued to be very tired.  During the day, my left hand began to feel tingly and numb.  The next morning, Wednesday, 8/25, I woke up still feeling tired and my lymph nodes were still swollen along with the tingly/numbness in left hand.  My left arm was slightly swollen and was beginning to feel itchy at the injection site. I went to work and called my doctor and scheduled an appointment for 1:00 pm that day.  When I saw my doctor, she noted the swollen lymph nodes and the slight swelling/rash on my left arm.  She felt all the symptoms I had been experiencing were a result of the vaccine.  I was curious about the tingling/numbness in my left arm and she thought that was inflammation as a result of the vaccine.  She told me to use an ice pack and topical steroid cream on my arm, a warm compress on my lymph nodes and Tylenol for pain.  I had put an ice pack on my arm that afternoon but the swelling continued to get worse.  By that evening the swelling in my arm had gotten much worse and the area was extremely itchy and was breaking out in hives.  I woke up at 1:30 am on Thursday, 8/26, with severe pain in my upper left arm and numbness in my hand.  I got up to check it and the hives had gotten worse and I couldn?t feel my hand.  I put the ice pack on my arm and took more Tylenol.  I went to work that day and continued to feel worse and the swelling/itching on my arm continued to get worse.  By that evening my arm was extremely swollen and I had a patch of hives that measured 5 inches tall and 4 inches wide on my upper left arm.  I continued to use the ice pack, topical steroid cream, calamine lotion, Tylenol and Benadryl for my arm.  The next day, Friday, 8/27, I felt exhausted again so I stayed home from work.  The swelling/pain/hives on my arm were the same and I continued to treat it with ice, Tylenol, antihistamine, steroid cream and calamine lotion.  The lymph nodes in my armpit and collar bone were still swollen and my left hand was still tingly/numb.  I sent an online message to my doctor telling her that I had gotten worse since she saw me on Wednesday explaining my issues and provided her with pictures of my arm.  She called me that evening and discussed my situation.  The next day, Saturday, 8/28, I still felt tired but had more energy.  It was also the first day that I didn?t wake up with new or worsening symptoms.  I continued to treat my arm with  ice, antihistamine and creams.  The next day, Sunday, 8/29, I woke up feeling better.  My hives were starting to fade out and the swelling was going down.  I woke up on Monday, 8/30, feeling about 80% normal and the hives were faded out and swelling of my arm was minimal.  Today is Thursday, 9/2, and my left arm is completely back to normal. I continue to have swollen lymph nodes in my left armpit and collarbone areas but appear to be a little smaller.  I continue to have tingling/numbness in my left hand that comes and goes but seems to be getting better.    I have celiac disease and the other side effect I experienced from 8/23 ? 8/30 was feeling like I had ingested gluten when I had not.  I experienced my normal tell-tale symptoms of being ?glutened? so I wonder if in response to the vaccine my body was producing antibodies to fight gluten even though I hadn?t ingested any.  That has cleared up now.
