Pfizer. First shot I didn't even feel it, 2nd shot hurt like hell. I personally think the pain from the 2nd shot was because of the technique the nurses had to use, it was like they were throwing a dart into my shoulder.
First day after the 2nd shot, I felt crappy but I couldn't tell if it was the usual first day off aches and pains(I work at a physical job and 5 days straight wears you down) or if it was the shot.
3 days later, that Monday evening I felt some pain in collar bone, a lymph node on my left collar bone had started to swell up and become rock hard. I had it checked out, they did an FNA(kinda like a biopsy for lymph nodes) and all it showed that it wasn't cancer and they think it was a reaction to the 2nd shot. About a week later, after the damn lymph node had somehow bigger, I ended up with a fever. Afterwards, the lymph node started shrinking.
Currently the lymph node is much smaller and soft to boot so I think I have turned the corner on my reaction.
