What do you mean added an injection?
I am 53, muscle troubles for many years (vitamin D significantly helps reduce the pain, cramping, weakness, and shaking). I have high cholesterol, intermittent high BP, a heart arrhythmia, hypothyroid, usually low or low normal iron and various red blood cell counts. B12 runs low side of normal without supplements.
When I received my Moderna within two minutes I felt “it” go down my left arm into my hand then over into my left upper chest then up the left side of my neck across my mouth and it tasted like the numbing agent dentists use. That whole process took about 5 minutes I think and lingered for about 30. I “know” a few other people who had the same thing happen. People in my local COVID Facebook group and one was one of their adult children. Knowing that put me at ease. Before I described what happened to me, I had never heard of that reaction. Actually, it was a woman in that group that described the taste perfectly before I had come up with the description of the taste.
I was worried it was causing inflammation, but now I think it was a nervous system reaction maybe. For the next 24 hours my arm was sore.
After the second shot I had all of that, but the feeling immediately after the shot was less pronounced, but the next day I was achy all over. It did not feel like fever ache, it was a muscle tight ache. Not like after exercising either.
I was experimented on too being a dependent treated in military facilities. I always knew it was experimental though and we could say no. I actually had a drug given to me in college that I didn’t realize I was in a trial until later.
