2nd Pfizer Vaccine shot

So I got my 2nd vaccination shot 2 days ago on Wednesday (4/21). It is true, though the first shot made me feel like I'm from Krypton as there was only a slight sore on the left arm where the shot was applied, the second shot had the same effect and more. I didn't feel much the first day, but on the second day (Yesterday) I did feel "Almost" feverish and felt some light ghost sores all over, left chest close to the heart, in the head, sometimes in both arms and thighs, etc. They are so light I do wonder if they are related to the vaccination or if it's just a coincidence form bad sleeping postures which occur to me often or gas in the body or something else completely. Of course, if I were to guess, I would say it's Pfizer, because of the statistics of 2nd shot effects on others.
