It felt like the flu shot, tender but not bothersome. Close to the 15 minutes I started feeling like  a pulling string feeling from my upper shoulder going up towards my neck. I let them know about it and they said to move it around. I was already moving it and massaging my arm. They told me to apply ice on it. They checked on me later and I stayed there for a little over an hour. Then I don't know if its because I was nervous or what but I felt hyper. The whole time before getting the vaccine I was talking a lot and after getting the vaccine I continued to talk a lot instead of feeling down. I continued to ice it. It felt like I was on caffeine. Finally I felt fine. I did not really have any pain or discomfort for the rest of the day. At 3 am in the morning I noticed the pain but I thought it was a dream. I was moaning and turning until I realized it was not a dream. I was having really severe aches and pain deep in my armpit. I did not take any medication so I went back to sleep. The first day I took Tylenol.  After the 3 am episode I was good for pretty much until early afternoon. When I got home I was eating my food and it felt like I was starting to get the pain again. I just iced it again and I was fine. Then, when the vsafe check in came in at around 2:30 that's when things changed. I went to the bathroom and I looked in the mirror and I noticed a little bulge in between my chest and arm. As I raised my arm I noticed a pulling sensation and it was hard to stretch. At this point I would be on the 24 hour mark. I freaked out. Its kind of a significant swelling. Earlier that day I did not notice any swelling. There was some discoloration in my skin. It was like an oval rectangular shape. The tissue was really soft and squishy. At that point I did take Ibuprofen. I just continued to iced it because I continued with the discomfort. The second day, the injection site did feel tender and sore as well. By the 4th day I did not feel anything. No pain. It was absolutely gone. The discoloration was gone. A week later after getting the vaccine its when I first had an episode when my heart was doing something weird, like palpitations and I had an anxiety attack. I breathe through it. I felt like I got through it. My blood pressure and pulse were high. 3 or 4 days after the second week I had another situation, worse than the first time. I was asleep and I woke up out of my sleep and I was feeling weird, my heart was doing the same weird thing. It reminded me when I got Covid. I started feeling shortness of breath. I immediately checked my blood pressure and oxygen. The readings were super high. I was feeling like I was going to go unconscious. I called 911 because I was by myself and my daughter. They came home and they evaluated me. My blood pressure had come down. They said they did not see any heart situation going on but that does not mean there is not something going on. They wanted me to go to the hospital but I could not go because I had to take care of my daughter. I told them I would call if necessary. I tried to calm myself with teas and meditations. Currently I find myself tired and wanting to sleep a lot. I am still dealing with anxiety. A week and a half after I called the doctor because I was outside and I had a feeling of a stabbing needle. I looked at my arm and there was no bump or anything but my vein was bulged out. I felt like all my veins were popping out. They said it was like a spasm.
